打印机常见故障处理办法

pr2e打印机的简单故障处理

pr2e打印机不进纸时的简单故障处理

1，打开顶盖，把打印头拨到最左边，按住面板三个键开机，听到响声后，将顶盖盖上。

2.连续按两下ST1键，等听到蜂鸣声的时候，将A4纸放进去，按ST2键一下，A4纸进取后，又出来。

3.等A4纸出来后，再重新放入机器，此时，打印机就会打印一组参数出来。

4.重新启动PR2E存折打印机。

日常用的打印机常见故障及排除方法：

一、打印机常见日常故障之打印效果与预览不同

一般这种情况是在文本编辑器下发生的，常见的如word或wps2000等，在预览时明明是格式整齐，但是打印出来去发现部分字体是重叠的。这种情况一般都是由于在编辑时设置不当适成的，其解决的方法是改变一下文件“页面属性”中的纸张大小、纸张类型、每行字数等，一般可以解决。

二、打印机常见日常故障之打印字迹不清晰

这种问题在平时使用打印机中非常的常见，一般来说这种情况主要和硬件的故障有关，遇到这种问题一般都应当注意打印机的一些关键部位。我们在这里就以喷墨打印机为例，遇到打印品颜色模糊、字体不清晰的情况，可以将故障锁定在喷头，先对打印头进行机器自动清洗，如果没有成功可以用柔软的吸水性较强的纸擦拭*近打印头的地方;如果上面的方法仍然不能解决的话，就只有重新安装打印机的驱动程序了。

三、打印机常见日常故障之无法打印大文件

这种情况在激光打印机中发生的较多，可能在打印小文件时还是正常的，但是打印大文件时就会死机，这种问题主要是软件故障，你可以查看硬盘上的剩余空间，删除一些无用文件，或者查询打印机内存数量，是否可以扩

容。

四、打印机常见日常故障之选择打印后打印机无反应

一般遇到这种情况时，系统通常会提示“请检查打印机是否联机及电缆连接是否正常”。一般原因可能是打印机电源线未插好;打印电缆未正确连接;接触不良;计算机并口损坏等情况。解决的方法主要有以下几种：1、如果按下打印电源开关后打印机能正常启动，就进bios设置里面去看一下并口设置。一般的打印机用的是ecp模式，也有些打印机不支持ecp 模式，此时可用ecp+epp，或“normal”方式。

2、如果上述的两种方法均无效，就需要着重检查打印电缆，先把电脑关掉，把打印电缆的两头拔下来重新插一下，注意不要带电拔插。果问题还不能解决的话，换个打印电缆试试，或者用替代法。

五、打印机常见日常故障之打印不完全

如果您遇到这样的问题，可以肯定地说是由软件故障引起的，可以在windows95/98内更改打印接口设置，依次选择“开始→设置→控制面板→系统→设备管理→端口→打印机端口→驱动程序→更改驱动程序→显示所有设备”，将“ecp打印端口”改成“打印机端口”后确认。

打印机常见硬件故障及处理方法：

症状一：打印机不装纸，. 装纸后还出现缺纸报警声，装一张纸胶辊不拉纸，需要装两张以上的纸胶辊才可以拉纸。原因分析一般针式或喷墨式打印机的字辊下都装有一个光电传感器，来检测是否缺纸。在正常的情况下，装纸后光电传感器感触到纸张的存

在，产生一个电讯号返回，控制面板上就给出一个有纸的信号。如果光电传感器长时间没有清洁，光电传感器表面就会附有纸屑、灰尘等，使传感器表面脏污，不能正确地感光，就会出现误报。以上这几种现象基本是同一问题，光电传感器表面脏污所致。

处理办法拔掉电源，打开机盖。对于大多数针式打印机(如epson lq- 1600k、star-3200等)，拿掉上盖板后，要先把与打印头平行*在打印头下部的一块小盖板拿掉(大约有20多厘米长1厘米宽)，把打印头推至这中间( 喷墨式打印机一般没有此小盖板)，这样可以拿掉上盖，否则是拿不下来的。卸掉打印机周边的螺丝(大多数在打印机底部)，慢慢活动就可以将外壳拆开，然后卸下黑色的进纸胶辊，要注意进纸辊两边是由一个切槽通过两个铁片卡住，只要用力推它，使它绕纸辊旋转，就可以拿下纸辊。此时能看见纸辊下有一小光电传感器，清除周围灰尘，用酒精棉轻拭光头，擦掉脏污，重新安装好纸辊、机盖等，通电开机，问题解决。

症状二：打印时字迹一边清晰，而另一边不清晰。原因分析此现象一般也是出现在针式打印机上，喷墨打印机也可能出现，不过几率较小，主要是打印头导轨与打印辊不平行，导致两者距离有远有近所致。处理办法可以调节打印头导轨与打印辊的间距，使其平行。具体做法是：分别拧松打印头导轨两边的螺母，在左右两边螺母下有一调节片，移动两边的调节片，逆时针转动调节片使间隙减小，顺时针可使间隙增大，最后把打印头导轨与打印辊调节平行就可解决问题。要注意调节时找准方向，可以逐渐调节，多试打几次。症状三：打印时感觉打印头受阻力，打印一会就停下发出长鸣或在原处震动。原因分析打印头导轨长时间滑动会变得干涩，打印头移动时就会受阻，到一定程度就可以使打印停止，严重时可以烧坏驱动电路。

处理办法在打印导轨上涂几滴仪表油，来回移动打印头，使其均匀。重新开机，如果还有此现象，那有可能是驱动电路烧坏，需要拿到维修部了。症状四：打印字符残缺不全，并且字符不清晰。原因分析对于喷墨打印机，可能有两方面原因：1. 墨盒墨尽;2. 打印机长时间不用或受日光直射，墨嘴堵塞。对于针式打印机，可能是以下几方面原因：1. 打印色带用得时间过长;2. 打印头长时间没有清洁，脏污太多;3. 打印头有断针;4. 打印头驱动电路有故障。

处理办法对于喷墨打印机，可以换新墨盒或注墨水，如果墨盒未用完，可以断定是墨嘴堵塞：拿下墨盒(对于墨盒喷嘴非一体的打印机，需要拿下喷嘴，但需要仔细)，把喷嘴放在温水中浸泡一会，注意，一定不要把电路板部分也浸在水中，否则后果不堪设想，用吸水纸吸走沾有的水滴，装上后再清洗几次喷嘴就可以了。对于针式打印机，可以调节一下打印头与打印辊间的间距(在打印头移动线的周围可以找到)，如果不行，可以换新色带，如果还不行，就需要清洁打印头了，方法是：卸掉打印头上的两个固定螺钉，拿下打印头，用针或小钩清除打印头前、后夹杂的脏污，一般都是长时间积累的色带纤维等，再在打印头的后部看得见针的地方滴几滴仪表油，以清除一些顽污，不装色带空打几张纸，再装上色带，这样问题基本就可以解决，如果是打印头断针或是驱动电路的问题，那只好拿到维修部去了。

症状五：打印机开机后没有任何反应，根本就不通电。原因分析打印机都有过电保护装置，当电流过大时就会引起过电保护，此现象出现基本是打印机保险管烧坏。处理办法打开机壳，在打印机内部电源部分找到保险管(内部电源部分在打印机的外接电源附近可以找到)，看其是否发黑，或用万用表测量一下是否烧坏，如果烧坏，换一个与其基本相符的保险管就可以了(保险管上都标有额定电流)。

症状六：打印时纸上出现一条条粗细不匀的黑线，严重时整张纸都是如此效果。原因分析此种现象一般出现在针式打印机上，原因是打印头过脏或者是打印头与打印辊的间距过小或打印纸张过厚引起。处理办法卸下打印头，清洗一下打印头，或是调节一下打

印头与打印辊间的间距。

给喷打加墨的应知事项1、如果墨盒与打印喷头是集成在一起的，那么在给墨盒加墨时，一定要注意保护墨盒上的喷嘴不受伤害，不然的话喷嘴一旦被堵塞或者损伤，墨盒就不能被反复利用了。另外由于墨盒在频繁的使用过程中，喷头可能会被溅回的纸张纤维堵塞，而导致喷头的输出效果变差，因此定期对喷头进行清洗也是非常有必要的;清洗喷头时，应尽量使用湿纸巾和无棉纸巾轻轻清洗喷嘴的边缘，而不要碰到喷嘴，接着再利用喷墨打印机控制面板上的清洗键来对喷头执行清洁动作，直到打印输出效果清晰为止。2、由于有的墨盒有专门的注墨孔，给这些墨盒注墨之前，一般都必须将墨盒注墨孔中的塞子先移开，然后按照正确的步骤填充完墨盒后，还必须将注墨孔的塞子重新盖回，不然的话，喷墨打印机重新工作时会发生甩墨现象，从而玷污喷墨打印机的内部面板。3、许多用户在给喷墨墨盒加墨时，一般都会选择在墨水指示灯提示墨水耗尽的情况下进行;但是对那些没有墨水指示灯的旧式喷墨打印机来说，就不能根据打印机提示来进行换墨了，不过这些没有墨水指示灯的喷墨墨盒大部分都是透明的，因此大家可以通过眼睛观察的方法来更换墨水，具体地说就是用眼睛观察墨水在墨盒中的剩余量来判断什么时候加墨，通常在墨水还有10%剩余量时对墨盒进行填充;要是连墨水的剩余量都无法观察到的话，只能观察最后的打印效果了，只要在打印页面中发现有断线现象就应该给墨盒加墨水了。

4、不少初次给喷打墨盒罐装墨水的用户，常常错误认为墨盒中的墨水应该罐满为止，这样可以延长墨盒的使用时间，其实我们在每次填充墨水时，最好将墨水罐装到整个墨盒容量的90%左右，如果超过这个容量的话，墨盒内部的海绵体可能无法吸收太多的墨水而产生墨水溢出的现象，从而污染喷墨打印机。

5、在给墨盒罐装好墨水后，最好不要立即将墨盒放回到墨盒架中，因为许多墨盒中都包含有吸收墨水用的海绵垫，而海绵垫吸收墨水速度比较缓慢，这样墨水罐进墨盒后，无法均匀地被海绵垫所吸收，所以在将墨盒放回到墨盒架之前，最好让墨盒先静置几分钟时间，以便让墨水慢慢渗透到海绵垫的各个角落，从而确保最终的打印质量。

打印机使用注意事项

由于打印机内部的部件比较精密，即使是普通的擦拭或者加润滑油都有可能会对打印质量产生不可低估的影像，所以内部的清理一定要谨慎小心，根据我的经验，列出以下可以清洗的部件，供大家参考。

1.墨粉保护装置

打印机的墨盒都会有一些衬垫，它们的作用是在传输纸张的滚筒系统中吸收过剩的墨粉。用户可以把它从机器中取出，用手工的方式进行清理。一般在新的墨盒中也会包含一个新的衬垫。

2.送纸滚筒

它们是打印机的传送部分，将纸张从纸槽拖曳到打印机的内部，但在这个过程中，纸张上玷污的油和灰尘也会在滚筒上沉淀，长时间不清洗就会导致卡纸和送纸错误，这也是打印机最容易出现的故障。在这里，我们可以用酒精泡过的棉花团或湿布清洗这些沉积物。此外，在一些办公设备专业用品商店有专门的滚筒清洁器。

3.冠状电线

它们是在打印机内部用来传送静电的专门电线。静电是用来将墨粉吸引到纸张的，但是灰尘的沉淀会影响静电的使用效率(特别是对于一些老式的激光打印机影响尤其严重)。用户可以使用棉布将灰尘轻轻擦去，但是请不要使用酒精或者其它溶剂，它们会影响打印机的效果，一般在老式激光打印机当中，冠状电线在打印机内部是裸露的。如果找不到，打印机手册中会指明它们的位置。

4.通风口

与计算机内部相似，许多激光打印机内部也有内部风扇，常年的工作会被灰尘和污物阻塞。我们必须保证定期清理通风口和风扇的页片，保持打印机内部的空气流动。

以上是激光打印机内部可以清洗的部件，但我们一定要注意：由于激光打印机都是使用高热的方法将墨粉吸附到纸张上。所以切记在刚刚完成打印机任务时进行打印机的清洗工作，并且注意所有带有温度警告标志的部件。在一些办公用品商店我们还可以看到一些专门的激光打印机的“清洁纸”出售，它们表面覆盖有特殊的纸张，可以吸附打印机纸张通路中的灰尘和过剩的墨粉，同时因为它们会经过完整的打印过程，所以对于打印机内部的清洗也是最彻底的。

打印机外部的清洗

与清洗内部比较起来，打印机的外部清洗总的来说是比较容易和安全的。一般用户在清理计算机硬件的外表面时可以使用清洗汽车内部时使用的清洁/保护喷雾剂，这种产品可以帮助减少静电，对于塑料的表面比较安全。可以将清洁剂喷在柔软的布上，然后用它擦拭设备的外壳(注意不要将喷雾剂喷入机器内部)，同时，在清洗打印机外部的时候，我们也可以通过空气出口，风扇通道和纸槽中吹入压缩空气，来清除灰尘和污物。

打印机虽然算不上是娇贵的产品，但由于长期处于高温的环境下，定期的清洗与维护可以有效的延长它的寿命。一般一月对外部进行一次清洗，两个月对内部进行一次内部清洗，可以大大提高打印机的工作效率，何乐而不为呢?

Printer common trouble processing method

Simple troubleshooting of pr2e printer

Simple troubleshooting pr2e printer paper at

1, open the top cover, the print head to the left, press and hold the three keys on the panel, after hearing the sound, the lid cover.

2. Continuous press the two button ST1, hear beep, put into a A4 paper, press ST2 type, A4 paper and enterprising, and came out.

3 A

4 out, again into the machine, then, will the printer to print a set of parameters.

4 restart PR2E passbook printer.

Common malfunction and troubleshooting method for daily use of printer:

One, the print effect and preview of printer common daily breakdown is different

This is usually the case in the text editor, such as word or WPS2000, etc., in the preview is clearly a neat format, but the print came out to find that some of the fonts are overlapping. This situation is generally due to improper settings when editing, the method is to change the file "page surface properties" in the paper size, paper type, the number of words per line, generally can be resolved.

Two, the printer is not clear the common daily breakdown of the print

This problem is usually used in the printer is very common, in general, this situation is mainly related to the failure of the hard part, encountered this problem should pay attention to some of the key parts of the printer. We are here to ink jet printer as an example, the color of the print product color, the font is not clear, can be locked in the nozzle, the first print head machine automatic cleaning, if not successful can use a soft absorbent paper wipe near the print head, if the above method still can not solve the case, only to re install the printer driver.

Three, printer common daily failure can not print large files

This is more likely to occur in the laser printer, it is possible to print a small file is normal, but when the print file will crash, this problem is mainly software failure, you can view the remaining space on the hard disk, delete some useless files, or check the number of printer memory, whether it can expand

V olume.

Four, the printer is common in the daily failure of the printer to print the printer no response In this case, the system will usually be prompted, "please check if the printer is connected to the cable and whether it is normal or not". General may be due to the printer is not plugged the power cord; print cable is not properly connected; poor contact; damage to the computer parallel port and other conditions. To solve the method mainly has the following several: 1, if the printing press the power switch the printer to normal after the launch, enter BIOS Setup to look at the parallel port settings. General printers use the ECP mode, and some printers do not support ECP mode, this time can be used ecp+epp, or "normal".

2, if the above two methods are invalid, you need to check on the print cable, put off the computer, print cable two pull down the re inserted, careful not to live plug. If the problem can not be solved, the replacement of a print cable to try, or replace.

Five, the printer is not complete, common daily breakdown of printing

If you encounter such problems, it can be sure that the software fault, you can change the print interface in windows95/98 settings, select the start - > Settings > > Control Panel > system > system > > Device Management > > port > driver > display all settings, the "ECP print port" to "printer port".

Printer common hardware failure and processing method:

Symptoms: printer paper. Paper also appeared after the paper shortage alarm sound, installed a piece of paper rollers do not pull paper and need to hold more than two pieces of paper rollers before they can pull the paper. Cause analysis of the general pin type or inkjet printer with a photoelectric sensor is equipped with a photoelectric sensor to detect whether the lack of paper. In normal circumstances, when the paper is loaded with paper, the photoelectric sensor is touched by the paper. If the photoelectric sensor for a long time not clean, photoelectric sensor surface will be attached to the scraps of paper, dust, etc., makes the sensor surface dirty, not photosensitive correctly, there will be false positives. Several of the above phenomenon is basically the same problem, the photoelectric sensor surface caused by dirt.

Handling method to unplug the power, open the machine cover. For most of the needle type printer (such as lq- 1600K Epson, star-3200, etc.), to remove the upper cover, and the print head parallel to the top of the print head of a small cover (about 20 cm long 1 cm wide), the print head pushed to the middle (inkjet printers generally do not have this small cover), so you can remove the cover, otherwise it can not get down. Unload printer peripheral screw (most) at the bottom of the printer and slowly activities can the shell open, and remove the black under the paper feed roller, attention should be paid to the feed roller on both sides by a cutting groove by two iron stuck, just push it and make it rotate around the roller, can get the paper and. At the same time the paper and saw a small photoelectric sensor, remove dirt around, with alcohol cotton swab head and rub off the stain, re install paper roller, a machine cover, start, solve the problem.

Symptoms two: when the print is clear, while the other side is not clear. Reason analysis of this phenomenon is generally appear in the needle type printer, ink jet printer may also occur, but the probability is small, mainly print head guide rail and print roller is not parallel, resulting in both of the distance is far from near. The processing method can adjust the distance between the print head guide rail and the printing roller, making it parallel. Specific approach is: the first two side of the print head guide rails on both sides of the nut, the left and right sides of the nut has a regulation, the adjustment of the two sides of the film, the counter clockwise rotation adjustment piece to reduce the gap, the last to print head guide rail parallel with the printing roller can solve the problem. Should pay attention to adjust the direction of the right direction, can be gradually adjusted, more than a few times to fight. Three symptoms: print the feeling when the print head resistance, print will stop ringing or vibration issued in place. Cause analysis of print head long rail sliding time will become dry, moves the print head will be blocked, to a certain extent can stop the printing, serious can burn the driving circuit.

Processing method in the printing of a few drops of oil on the print, back and forth to move the print head, so that it is uniform. Re boot, if there is this phenomenon, it may be the driver needs to get burned, repair department. Four symptoms: print characters and incomplete, character is not clear. Reasons for the analysis of ink jet printers, there may be two reasons: 1 ink cartridges, 2 long time without or subject to direct sunlight, ink nozzle blockage. For needle type printer may be the following reasons: 1. Print ribbon used when too long; 2. Print head for a long time not

clean, dirty too much; 3. Print head broken needle; 4. Print head driving circuit fault.

Approach for an inkjet printer, can change new cartridges or injecting ink. When the ink cartridge is unused, it can be concluded that is ink nozzle clogging: take cartridges (for cartridge of the nozzle is one of the printer, you need to get under the nozzle, but need to be carefully), put the nozzle in the warm water soak for a while. Note that must not be the portion of the circuit board is also immersed in the water, otherwise the consequences could be disastrous, with absorbent paper suck dip some water, installed after washing several times nozzle can be. For the printer, can adjust the distance between the printing head and printing roller (around the print head moving line can be found), if not, can change the new ribbon, if not, you need to clean the print head, the method is: remove the print head of the two fixing screws, with the print head, with a clear print head, needle or hooks after inclusion of dirt, is generally a long time accumulation of ribbon fiber, the rear visible print head needle in place a few drops of oil to remove the instrument, some stubborn dirt, do not install the ribbon playing a few sheets of paper, and then put on a ribbon, this problem can be resolved, if the print head is broken needle or drive circuit, it had to get to the repair department.

Symptoms five: the printer does not have any response after the boot, simply do not work. Analysis of the causes of printers have overcurrent protection device, when the current is too large will lead to electrical protection, this phenomenon is basically printer insurance pipe burn. Approach to open the cabinet, inside the printer power supply part find an insurance tube (internal power supply part in playing the printing machine is connected with a power supply near can be found), to see whether it is black, or with a multimeter measuring about whether the burn. If burned, insurance and consistent exchange tube can be (insurance tube are marked with rated current).

Six symptoms: printing paper sanritusone of uneven thickness of the black line, serious when the entire piece of paper is like this effect. Reason analysis this phenomenon is generally appear in the needle type printer, the reason is that the print head is too dirty or print head and the printing roller spacing is too small or too thick to print paper. Processing method to remove the print head, clean the print head, or to adjust the print head and the spacing between the printing roller.

To penda and Mexico should know matters 1, if the print cartridges and nozzle is integrated together, then for the ink cartridge with ink, be sure to pay attention to protect the cartridge nozzle from harm, otherwise nozzle when a blocked or damaged, the ink can not be repeated use of the. Also due to the use of ink cartridges in the process of frequent use, the nozzle may be splashed back into the paper fiber, resulting in poor output effect, so it is necessary to clean the nozzle is also very necessary; cleaning nozzle, should try to use wet paper towels and no cotton towel gently clean the nozzle, and do not touch the nozzle, and then use the ink jet printer control panel on the cleaning action, until the print output effect is clear. 2, because some cartridges have a special ink filling hole, to these cartridges Zhumo before, the general must be the ink in the ink injection hole plug first remove the, then in accordance with the correct procedure finished filling ink cartridge, must also be refilling hole plug to the back of the cover, otherwise, ink-jet printing machine to work will happen to jilt ink phenomenon to smear inkjet printer inside the panel. 3, many users in the ink jet ink, the general will choose to ink indicator light ink, but for the old ink

jet printer, the ink can not be based on the printer to change ink, but these are not ink indicator of ink jet cartridges are transparent, so we can observe the method through the eyes 4, many for the first time to penda cartridge canned ink users, often wrong that the ink cartridges in the tank is full now, so you can extend the use time of the cartridge, in fact, we each filled with ink, it is best to ink cans to about 90% of the capacity of the cartridge, such as fruit more than the capacity, inside the cartridge in the corpus cavernosum may can not absorb too much ink ink overflow phenomenon, thereby causing the pollution to the ink jet printer.

5, in the ink cartridge can be good ink, it is best not to put the cartridge back into the box, because many of the cartridges are contained in the use of ink sponge pad, and sponge pad ink absorption, so that the ink can be absorbed by the sponge pad, so that the ink cartridge is placed in a few minutes, so that the ink slowly penetrate into every corner of the sponge pad, so as to ensure the final print quality.

Printer usage notes

Due to the internal components of the printer is more sophisticated, even if it is common to wipe or add oil are likely to produce an image of the print quality can not be underestimated, so the internal clean-up must be careful, according to my experience, the following can be cleaned parts, for large reference.

1 toner protection device

Printer cartridges will have some pads, their role is excess toner absorption in the system of the paper transmission drum. The user can remove it from the machine, use the manual way to clean up. General in the new ink cartridge also contains a new liner.

2 paper roller

They are the transmission portion of the printer, the paper from the paper groove drag to the printer, but in the process, paper was stained with the grease and dirt will precipitate in the roller, a long time without cleaning will lead to cardboard and paper feed error, which is printers are most prone to failure. Here, we can use the alcohol soaked cotton or cloth to clean these sediments. In addition, there are special roller cleaner in some professional office equipment stores.

3 coronary wire

They are specialized wires that are used to transmit electricity within the printer. Static electricity is used to toner attracted to the paper, but dust precipitation will static electricity use efficiency (especially for some old-fashioned laser printer influence especially). Users can use cotton cloth to gently wipe the dust, but please do not use alcohol or other solvents, they will affect the effect of the printer, the general in the old-fashioned laser printer, the printer is exposed to the.

Similar to the computer internal, many laser printers have internal fans, the perennial work will be dust and dirt blocking. We must ensure that regular cleaning of air vents and leaf fan, keep the air flow inside the printer.

Printer external cleaning

Compared with the internal cleaning, the external cleaning of the printer is relatively easy and safe. General users can use the cleaning / protection spray when cleaning the outside surface of the computer hardware, which can help reduce the static electricity, the surface of the plastic is relatively safe. Can the cleaning agents are sprayed on the soft cloth, and then use it to wipe the equipment shell (be careful not to the spray is injected into the interior of the machine, at the same time, when cleaning the outside of the printer, we can also through the air outlet, fan channel and paper slot blowing compressed air, to remove dust and dirt.

Printer is delicate products, although not, but because of a long time in the environment of high temperature, regular cleaning and maintenance can prolong its life. January in general outside a cleaning and two months of internal to an internal cleaning, can greatly improve the working efficiency of the printer, why not do it?

打印机的几种常见故障和处理方法

打印机的几种常见故障和处理方法 https://www.360docs.net/doc/4916571503.html,2006-3-10 一、打印大文件死机：有的激光打印机在打印小的文件时正常，但打印大文件时会死机。处理方法是：查看硬盘上的剩余空间。删除一些无用文件，或者查询打印机内存数量，是否可以扩容？二、打印时出现一个红叉：一般用EPSON－MJ1500打印机，经常发生打印时出现一个红叉的现象。处理方法是：看进纸是否顺利，使用的纸张是否符合要求。因为一些打印机要80克或75克纸。而有的打印纸的正反面放反了也会造成进纸不畅而出现红叉。如果是水平进纸，应使光滑面朝下；如果是垂直方向进纸，应使光滑面朝前。三、不定时的不打印： EPSON 440打印机在驻留VRV杀毒软件时不一定什么时候就不能打印。处理方法：依次将频幕右下角任务栏上的图标挂起，看结果如何。多可以使用鼠标右键单击图标，选择“挂起”功能即可。如KILL 98 的实时监测软件，可以选择“挂起实施监控器”，但若选择“关闭实施监控器”则可能使KILL 98 很难恢复，即使重装KILL 98 。四、打印机信号不同步：有的电脑使用EPSON打印机可以正常输出，但使用HP LASER JET 1100就不正常了，打印测试页异常：标题右偏，打印的文件少几个。HP打印机自检是正常使用。使用Windows 98 的 HP LASER JET 驱动可以正常打印测试页，但字的质量不高。处理方法：尝试安装 Windows 9X 光盘上的HP LASER JET 打印驱动程序，然后再改回 HP LASER JET 打印驱动程序，然后再改回 HP LASER JET 1100 的打印驱动。

SS6B型机车常见故障应急处理

SS6B型机车常见故障应急处理（一）受电弓升不起处理： 1.有门联锁的撞击声；（1）换弓运行；（2）检查52调压阀（风压不低于500KPA）。 2.无门联锁的撞击声（1) 检查602QA、570QS电钥匙，570QS虚接则换另一端电钥匙；（2）287YV不吸合则检查入库开关20QP、50QP及车顶门开关297QP是否吸合。（二）主断路器故障处理： 1、合主断不闭合，确认调速手柄是否在“0”位，劈相机扳键是否断开，主断扳钮是否正常，断开自动过分相装置； 2、确认受电弓降下，人为顶合闸电磁铁，闭合主断，继续运行； 3、主断断不开，运行中密切注意显示屏，如有故障或需断主断时，可采用降弓的方法。（过分相时必须关闭所有辅助机组）。（三）劈相机不能正常启动处理： 1、观察辅压是否接近390V，若电压过低，重新分、合主断； 2、检查三相自动开关215QA、216QA和辅机电源开关605QA，动作则恢复重启（先扳到最下方，再向上扳到位）； 3、将第一劈相机隔离开关置“故障位”启动第二劈相机，仍不能启动，恢复第一劈相机故障开关； 4、劈相机I启动3秒后启动电阻甩不开，人为按压Ⅰ低压柜566KA。（过分相时必须重复此操作）； 5、劈相机启动电阻263R烧断，将296QS打至故障位，换另一组劈相机启动电阻。（四）压缩机不打风处理： 1、用强泵打风维持运行； 2、将I低压柜I压缩机隔离开关579QS置“故障位”，用第II压缩机维持运行（闭合副台备用压缩机扳钮）； 3、检查压缩机三相自动开关是否动作（先扳到最下方，再向上扳到位）。（五）牵引通风机不起处理： 1、检查故障显示屏的故障显示，检查对应通风机三相空气开关（先扳到最下方，再向上扳到位）； 2、将相应故障风机隔离开关置“故障”位，切除相应牵引电机。（六）两位置转换开关不转换处理： 1、换副台操纵； 2、人为转换开关上两个电空阀均得电，则为窜电（多发生在换室或副台操纵后换主台操纵），确认各主、副台司控器是否在零位，否则使其回零位；

打印机常见硬件故障及解决方法

打印机常见硬件故障及解决方法症状一：打印机不装纸，装纸后还出现缺纸报警声，装一张纸胶辊不拉纸，需要装两张以上的纸胶辊才可以拉纸。原因分析：一般针式或喷墨式打印机的字辊下都装有一个光电传感器，来检测是否缺纸。在正常的情况下，装纸后光电传感器感触到纸张的存在，产生一个电讯号返回，控制面板上就给出一个有纸的信号。如果光电传感器长时间没有清洁，光电传感器表面就会附有纸屑、灰尘等，使传感器表面脏污，不能正确地感光，就会出现误报。以上这几种现象基本是同一问题，光电传感器表面脏污所致。解决方法：拔掉电源，打开机盖。对于大多数针式打印机（如EPSON LQ- 1600K、STAR-3200等），拿掉上盖板后，要先把与打印头平行靠在打印头下部的一块小盖板拿掉（大约有20多厘米长1厘米宽），把打印头推至这中间（喷墨式打印机一般没有此小盖板），这样可以拿掉上盖，否则是拿不下来的。卸掉打印机周边的螺丝（大多数在打印机底部），慢慢活动就可以将外壳拆开，然后卸下黑色的进纸胶辊，

要注意进纸辊两边是由一个切槽通过两个铁片卡住，只要用力推它，使它绕纸辊旋转，就可以拿下纸辊。此时能看见纸辊下有一小光电传感器，清除周围灰尘，用酒精棉轻拭光头，擦掉脏污，重新安装好纸辊、机盖等，通电开机，问题解决。症状二：打印时字迹一边清晰，而另一边不清晰。原因分析此现象一般也是出现在针式打印机上，喷墨打印机也可能出现，不过几率较小，主要是打印头导轨与打印辊不平行，导致两者距离有远有近所致。解决方法：可以调节打印头导轨与打印辊的间距，使其平行。具体做法是：分别拧松打印头导轨两边的螺母，在左右两边螺母下有一调节片，移动两边的调节片，逆时针转动调节片使间隙减小，顺时针可使间隙增大，最后把打印头导轨与打印辊调节平行就可解决问题。要注意调节时找准方向，可以逐渐调节，多试打几次。症状三：打印时感觉打印头受阻力，打印一会就停下发出长鸣或在原处震动。原因分析打印头导轨长时间滑动会变得干涩，打印头移动时就会受阻，到一定程度就可以使打印停止，严重时可以烧坏驱

常见仪表常见故障及处理办法

仪表常见故障检查及分析处理一、磁翻板液位计： 1、故障现象：a、中控远传液位和现场液位对不上或者进液排液时液位无变化；b、现场液位计和中控远传均没有问题的情况下，中控和现场液位对不上； 2、故障分析：a、在确定远传液位准确的情况下，一般怀疑为液位计液相堵塞造成磁浮子卡住，b、现场液位变送器不是线性； 3、处理办法：a、关闭气相和液相一次阀，打开排液阀把内部液体和气体全部排干净，然后再慢慢打开液相一次阀和气相一次阀，如果液位还是对不上，就进行多次重复的冲洗，直到液位恢复正常为止；b、对液位计变送器进行线性校验。二、3051压力变送器：压力变送器的常见故障及排除 1)3051压力变送器输出信号不稳出现这种情况应考虑A.压力源本身是一个不稳定的压力B.仪表或压力传感器抗干扰能力不强C.传感器接线不牢D.传感器本身振动很厉害E.传感器故障 2)加压变送器输出不变化，再加压变送器输出突然变化，泄压变送器零位回不去,检查传感器器密封圈，一般是因为密封圈规格原因(太软或太厚)，传感器拧紧时，密封圈被压缩到传感器引压口里面堵塞传感器，加压时压力介质进不去，但是压力很大时突然冲开密封圈，压力传感器受到压力而变化，而压力再次降低时，密封圈又回位堵住引压口，残存的压力释放不出，因此传感器零位又下不来。排除此原

因方法是将传感器卸下看零位是否正常，如果正常更换密封圈再试。 3)3051压力变送器接电无输出 a)接错线(仪表和传感器都要检查) b)导线本身的断路或短路 c)电源无输出或电源不匹配 d)仪表损坏或仪表不匹配 e)传感器损坏总体来说对3051压力变送器在使用过程中出现的一些故障分析和处理主要由以下几种方法。 a)替换法：准备一块正常使用的3051压力变送器直接替换怀疑有故障的这样可以简单快捷的判定是3051压力变送器本身的故障还是管路或其他设备的故障。 b)断路法：将怀疑有故障的部分与其它部分分开来，查看故障是否消失，如果消失，则确定故障所在，否则可进行下一步查找，如：智能差压变送器不能正常Hart远程通讯，可将电源从仪表本体上断开，用现场另加电源的方法为变送器通电进行通讯，以查看是否电缆是否叠加约2kHz的电磁信号而干扰通讯。 c)短路检测：在保证安全的情况下，将相关部分回路直接短接，如：差变送器输出值偏小，可将导压管断开，从一次取压阀外直接将差压信号直接引到差压变送器双侧，观察变送器输出，以判断导压管路的堵、漏的连通性三、雷达液位计：

交换机常见的故障类型及分析排查

交换机常见的故障类型及分析排查交换机运行中出现故障是不可避免的，但出现故障后应当迅速地进行处理，尽快查出故障点，排除故障，这是网管人员应尽的职责。但是要做到这一点，就必须了解交换机故障的类型及具备对故障进行分析和处理的能力。为此，本文就交换机常出现的故障类型及分析排查的方法进行简要的介绍。电源故障由于外部供电不稳定，电源线路老化或者雷击等原因导致电源损坏或者风扇停转，以致不能正常工作。或者由于电源缘故导致机内其他部件的损坏都会使交换机出现问题。假如交换机面板上的POWER指示灯是绿色的，就表示是正常的;假如该指示灯灭了，则说明交换机没有正常供电。这类问题很轻易发现，也很轻易解决，同时也是最轻易预防的。针对这类故障，首先应该做好外部电源的供给工作，一般通过引入独立的电力线来提供独立的电源，并添加稳压器来避免瞬间高压或低压现象。假如条件答应，可以添加UPS(不间断电源)来保证交换机的正常供电，有的UPS提供稳压功能，而有的没有，选择时要注重。在机房内设置专业的避雷措施，来避免雷电对交换机的伤害。现在有很多做避雷工程的专业公司，实施网络布线时可以考虑。

端口故障这是最常见的硬件故障，无论是光纤端口还是双绞线的RJ-45端口，在插拔接头时一定要小心。假如不小心把光纤插头弄脏，可能导致光纤端口污染而不能正常通信。我们经常看到很多人喜欢带电插拔接头，理论上讲是可以的，但是这样也无意中增加了端口的故障发生率。在搬运时不小心，也可能导致端口物理损坏。假如购买的水晶头尺寸偏大，插入交换机时，也轻易破坏端口。此外，假如接在端口上的双绞线有一段暴露在室外，万一这根电缆被雷电击中，就会导致所连交换机端口被击坏，或者造成更加不可预料的损伤。一般情况下，端口故障是某一个或者几个端口损坏。所以，在排除了端口所连计算机的故障后，可以通过更换所连端口，来判定其是否损坏。碰到此类故障，可以在电源关闭后，用酒精棉球清洗端口。假如端口确实被损坏，那就只能更换端口了。模块故障交换机是由很多模块组成，比如：堆叠模块、治理模块(也叫控制模块)、扩展模块等。这些模块发生故障的几率很小，不过一旦出现问题，就会遭受巨大的经济损失。假如插拔模块时不小心，或者搬运交换机时受到碰撞，或者电源不稳定等情况，都可能导致此类故障的发生。当然上面提到的这3个模块都有外部接口，比较轻易辨认，有的还可以通过模块上的指示灯来辨别故障。比如：堆叠模块上有一个扁平的

常见打印机故障及解决的方法

1.故障现象：发出打印命令后，打印机无反应，系统提示打印机是否联机及电缆连接是否正常。分析与维修：这可能是打印机电源线末插好、打印电缆未正确连接或接触不良、计算机并口损坏等原因造成的。先按打印机开关，看打印机能不能启动。如不能启动(电源灯不亮)，先检查打印机电源线是否与电源及打印机后的电源插孔正确连接。在关机状态下把电源线重插一遍，并换一个电源插座试一下，看能否解决问题。如果按下电源开关后，打印机能正常启动，就进CMOS设置里看一下并口设置是否设置正确。一般的打印机用的是ECP模式，也有些打印机不支持ECP模式，此时可用ECP+EPP，或NORMAL。如问题还未解决，则着重检查打印电缆。先把电脑关掉，把打印电缆从主机的并口上拔下，并重新插好，再把打印电缆的另一端从打印机后的并口上拔下再重新插好。注意，一定要把主机关掉，不要带电拔插，否则可能损坏打印机！如果问题还不能解决，就换根打印电缆试试。再不行，那就是主板并口有问题了。 2.故障现象：使用网络打印机时，无法打印或出现找不到网络打印机的提示。分析与维修：先检查连接打印机的电脑上的打印机设置是否正确，并且确定该打印机已共享。然后检查远程使用网络打印机的电脑上的打印机设置是否正确。注意，设置都正确但是仍然无法打印这种情况经常可能碰到，一般我们在使用网络打印机的电脑上，把正确的打印机驱动程序重装一遍，问题就可以解决。 3.故障现象：打印机不能检测墨水类型或打印出的字符模糊不清。分析与维修：先对打印头进行清洗(很多打印机的驱动程序里提供了清洗打印头命令，直接使用该命令即可)。如果长时间没使用打印机，就要多清洗几次。如果你对拆卸和安装墨盒比较熟悉，最好把墨盒拆下来，在靠近打印头的地方用柔软的、吸水性较强的纸擦千净。如果还不能解决，那可能就是打印机驱动程序有问题，把与打印机对应的打印机驱动程序重新安装一遍，一般都能解决问题。 4.故障现象：用Word等字处理软件编辑好的文件，在打印预览时排列得整整齐齐，但用打印机打印出来后，纸上有部分文字重叠。分析与维修：这一般是由于编辑时设置不当造成的，改变一下文件页面属性中的纸张大小、纸张类型，每行字数等选项，大部分问题可以解决。

交换机常见故障和排障方法交换机的优越性能和价钱的大幅度降落，促使了交换机的迅速普及。网络管理员在工作中经常会遇到各种各样的交换机故障，如何迅速、正确地查出故障并消除故障呢？本文就常见的故障类型和排障步骤做一个简略的介绍。由于交换机在公司网络中利用范畴非常普遍，从低端到中端，从中端到咼端，几乎涉及每个级别的产品，所以交换机I产生故障的机率比路由器，硬件防火墙等要高很多，这也是为什么我们首先讨论交换机故障的分类与消除故障步骤的原因。 ,交换机故障分类: 交换机故障一般可以分为硬件故障和软件故障两大类。硬件故障重要指交换机电源、背板、模块、端口等部件的故障，可以分为以下几类。 (1)电源故障: 由于外部供电不稳定，或者电源线路老化或者雷击等原因导致电源毁坏或者风扇停滞，从而不能正常工作。由于电源缘故而导致机内其他部件毁坏的事情也经常产生。如果面板上的POWE指点灯是绿色的，就表示是正常的；如果该指点灯灭了，则解释交换机没有正常供电。这类问题很容易发现，也很容易解决，同时也是最容易预防的。针对这类故障，首先应该做好外部电源的供应工作，一般通过引入独立的电力线来供应独立的电源，并添加稳压器来避免瞬间高压或低压现象。如果条件允许，可以添加UPS(不间断电源)来保证交换机的正常供电，有的UPS供应稳压功效，而有的没有，选择时要注意。在机房内设置专业的避雷方法，来避免雷电对交换机的伤害。现在有很多做避雷工程的专业公司，履行网络布线时可以斟酌。 (2)端口故障: 这是最常见的硬件故障，无论是光纤端口还是双绞线的RJ-45端口，在插拔接头时必定要当心。如果不当心把光纤插头弄脏，可能导致光纤端口污染而不能正常通讯。我们经常看到很多人喜欢带电插拔接头，理论上讲是可以的，但是这样也无意中增加了端口的故障产生率。在搬运时不当心，也可能导致端口物理毁坏。如果购置的水晶头尺寸偏大，插入交换机时，也容易毁坏端口。此外，如果接在端口上的双绞线有一段暴露在室外,万一这根电缆被雷电击中，就会导致所连交换机端口被击坏，或者造成更加不可预见的损伤。一般情况下，端口故障是某一个或者几个端口毁坏。所以，在消除了端口所连计算机的故障后，可以通过更换所连端口，来断定其是否毁坏。遇到此类故障，

打印机常见故障解决方法 1、现在打印机已经成为了在人们的工作和生活中经常用到的电脑产品了，而由于是经常使用的产品，所以人们经常会遇到这样或者那样一些问题，而这些问题如果请维修人员修理不仅要花一些钱，更重要的耽误工作。其实打印机的内部并不复杂，一般的问题用户完全可以自己动手解决，下面我就向大家介绍一些简单的维修方法。维修打印机之前需要对打印机的问题作出一些了解。打印机出现问题后，首先是利用打印机自检系统来进行检测，可能通过打印机自带的指示灯或者是蜂鸣器的声音来加以判断，其中指示灯可以指示出最基本的故障，包括缺纸、缺墨、没有电源等情况。蜂呜器的判断主要是依*你的听觉，比如大多数打印机蜂鸣器以一声长鸣来表示准备就绪可以开始打印了，以短促的声音来表示打印机有故障等。其次，可以进行线路观察，从检测打印机电缆开始(包括端口、通道、打印线的检测)，再分析打印机的内部结构(包括托纸架、进纸口、打印头等)，看部件是否正确工作，针对不同的故障情况锁定相关的部件，再确定存在问题的部件。再次，可以使用测试法，进行测试页打印或者局部测试打印机内部件，看故障原因。当然打印机的另一个故障是软件故障，类似的故障就需要通过升级驱动程序或者访问其官方网站得到解决。下面我们就针对一些打印机的故障来进行一下说明。

一、打印效果与预览不同一般这种情况是在文本编辑器下发生的，常见的如Word或WPS2000等，在预览时明明是格式整齐，但是打印出来去发现部分字体是重叠的。这种情况一般都是由于在编辑时设置不当适成的，其解决的方法是改变一下文件“页面属性”中的纸张大小、纸张类型、每行字数等，一般可以解决。二、打印字迹不清晰这种问题在平时使用打印机中非常的常见，一般来说这种情况主要和硬件的故障有关，遇到这种问题一般都应当注意打印机的一些关键部位。我们在这里就以喷墨打印机为例，遇到打印品颜色模糊、字体不清晰的情况，可以将故障锁定在喷头，先对打印头进行机器自动清洗，如果没有成功可以用柔软的吸水性较强的纸擦拭*近打印头的地方；如果上面的方法仍然不能解决的话，就只有重新安装打印机的驱动程序了。三、无法打印大文件这种情况在激光打印机中发生的较多，可能在打印小文件时还是正常的，但是打印大文件时就会死机，这种问题主要是软件故障，你可以查看硬盘上的剩余空间，删除一些无用文件，或者查询打印机内存数量，是否可以扩容。

几种典型交换机常见的故障以及解决办法

几种典型交换机常见的故障以及解决办法计算机中有很多的部件都是随着计算机的运行时刻在工作，交换机、路由器这样的网络设备，在没有断电的情况下也时刻处于工作状态，无论一台交换机的性能有多好，时间工作长，难免不会出现故障，尽管交换机的故障多种多样，而且经常出现的也就这么几种。下面为大家归纳了交换机的几类典型的故障及其解决方法。 1.端口故障故障现象：整个网络的运作正常，但个别的机器不能正常通信。故障原因：这是交换机故障中最常见的，如果光纤插头或RJ-45端口脏了，可能导致端口污染而不能正常通信。还有，平常很多人都喜欢带电插拔接头，在理论上说似乎并没有不妥，但实际上经常这样的话就无意中增加了端口的故障发生率;在搬运时的不小心，也可能导致端口物理损坏;购买的水晶头尺寸偏大，插入交换机时，也很容易破坏端口。此外，如果接在端口上的双绞线有一段暴露在室外，万一这根电缆被雷电击中，就会导致所连交换机端口被击坏。解决方法：一般情况下，端口故障是个别的端口损坏，先检查出现问题的计算机，在排除了端口所连计算机的故障后，可以通过更换所连端口，来判断其是否端口问题，若更换端口后问题能解决的话，再进一步判断是端口的何种缘故。关闭电源后，用酒精棉球清洗端口，如果端口确实被损坏，那就只能更换端口了。此外，无论是光纤端口还是双绞线的RJ-45端口，在插拔接头时一定要小心，建议插拔时最好不要带电操作。 2.电路板故障故障现象：有一个电脑室经常出现一部分电脑不能访问服务器的现象。故障原因：交换机一般是由主电路板和供电电路板组成，造成这种故障一般都是这两个部分出现了问题。而造成电路板不能正常工作的主要因素有：电路板上的元器件受损或基板不良，硬件工注不合适和硬件更新后以及由于兼容问题而造成的电路板块类型不合适等。解决方法：首先确定究竟是主电路板还是供电电路板出现问题，先从电源部分开始检查，用万能表在去掉主电路板负载的情况下通电测量，看测量出的指标是否正常，若不正常，则换用一个AT电源，输入电源到主电路板，交换机前面板的指示灯恢复正常的亮度和颜色，而所连接这台交换机的电脑正常互访，就说明是供电电路板出现了问题。若以上操作无效的话，问题就应该是出现在主电路板上了。 3.电源故障故障现象：开启交换机后，交换机没有正常运作，而且发现面板上的POWER指示灯并没有亮，而且风扇也不转动。故障原因：这种故障通常是由于外部供电环境的不稳定，或者是电源线路老化，又或者是由于遭受雷击等而导致电源损坏或者风扇停止，从而导致交换机不能正常工作。还有可能是由于电源缘故而导致交换机机内的其他部件坏的损坏。解决方法：这类问题很容易发现也很容易解决，当发生这种故障时，首先检查电源系统，看看供电插座有没有电流，电压是否正常。要是供电正常的话，那就要检查电源线是否有所损坏，有没有松动等，若电源线损坏的话就更换一条，松动了的话就重新插好。如果问题还没有解决，那问题就应该落在交换机的电源或者是机内的其他部件损坏了。预防方法也比较简单，首先要做的就是保证外部供电环境的稳定，这可以通过引入独立的电力线来提供独立的电源，并添加稳压器来避免瞬间高压或低压象。可能的话，建议最好配置UPS系统。还有的就是采取必要的避雷措施，以防雷电对交换机造成的损害。连接电缆和配线架跳线、配置不当、系统数据的问题也时有发生，此外，局数据错误也会对整个交换局造成影响，而用户数据被错误设置，则会对某个用户产生影响，还有的就是

总结交换机常见故障的分类和排障步骤

总结交换机常见故障的一般分类和排障步骤交换机的优越性能和价格的大幅度下降，促使了交换机的迅速普及。网络管理员在工作中经常会遇到各种各样的交换机故障，如何迅速、准确地查出故障并排除故障呢?本文就常见的故障类型和排障步骤做一个简单的介绍。由于交换机在公司网络中应用范围非常广泛，从低端到中端，从中端到高端，几乎涉及每个级别的产品，所以交换机发生故障的机率比路由器，硬件防火墙等要高很多，这也是为什么我们首先讨论交换机故障的分类与排除故障步骤的原因。一，交换机故障分类: 交换机故障一般可以分为硬件故障和软件故障两大类。硬件故障主要指交换机电源、背板、模块、端口等部件的故障，可以分为以下几类。 (1)电源故障: 由于外部供电不稳定，或者电源线路老化或者雷击等原因导致电源损坏或者风扇停止，从而不能正常工作。由于电源缘故而导致机内其他部件损坏的事情也经常发生。如果面板上的POWER指示灯是绿色的，就表示是正常的;如果该指示灯灭了，则说明交换机没有正常供电。这类问题很容易发现，也很容易解决，同时也是最容易预防的。针对这类故障，首先应该做好外部电源的供应工作，一般通过引入独立的电力线来提供独立的电源，并添加稳压器来避免瞬间高压或低压现象。如果条件允许，可以添加UPS(不间断电源)来保证交换机的正常供电，有的UPS提供稳压功能，而有的没有，选择时要注意。在机房内设置专业的避雷措施，来避免雷电对交换机的伤害。现在有很多做避雷工程的专业公司，实施网络布线时可以考虑。 (2)端口故障: 这是最常见的硬件故障，无论是光纤端口还是双绞线的RJ-45端口，在插拔接头时一定要小心。如果不小心把光纤插头弄脏，可能导致光纤端口污染而不能正常通信。我们经常看到很多人喜欢带电插拔接头，理论上讲是可以的，但是这样也无意中增加了端口的故障发生率。在搬运时不小心，也可能导致端口物理损坏。如果购买的水晶头尺寸偏大，插入交换机时，也容易破坏端口。此外，如果接在端口上的双绞线有一段暴露在室外，万一这根电缆被雷电击中，就会导致所连交换机端口被击坏，或者造成更加不可预料的损伤。

打印机常见问题及解决方法

打印机无法打印解决方法：一、使打印机处于联机状态。如果打印机没有处于联机状态，自然是无法打印了。二、重新开启打印机。如果打印机处于联机状态仍无法打印文档，此时你可以重新开启打印机，不仅清除了打印机内存，还能解决不少的打印故障。三、将打印机设置为默认打印机。步骤如下: 1.单击Windows“开始”菜单，指向“设置”，单击“打印机”，打开“打印机”窗口。 2.右键单击打印机图标，系统弹出快捷菜单，单击其中的“设为默认值”。四、取消暂停打印。方法是:在“打印机”窗口，右键单击在用的打印机图标，然后单击以清除“暂停打印”选项前的对号“√”。五、使硬盘上的可用空间不低于10MB。如果可用硬盘空间小于10MB，必须释放更多的空间系统才能完成打印任务。这时，请单击“磁盘清理”按钮，然后在“要删除的文件”列表框中，选中要删除的文件类型，单击“确定”按钮。六、增加打印机的超时设置。检查或更改超时设置，步骤如下: 1.在“打印机”窗口，右键单击打印机图标，再单击“属性”。 2.单击“详细资料”选项卡，在“超时设置”下增加各项超时设置。“未选定”项是指定Window s 等待打印机进入联机状态的时间，超过指定时间之后就将显示错误消息。七、确保打印到合适的本地打印机端口。步骤如下:

1.在“打印机”窗口，右键单击打印机图标，再单击“属性”。 2.单击“详细资料”选项卡，在“打印到以下端口”框中，确保已将打印机设置到适当的端口。最常用的端口设置为“LPT1”，也有打印机使用USB端口。八、程序生成的输出不正确。要确定程序生成的输出是否正确，可以采用通过其他程序打印文档的方法验证。我们以“记事本”打印测试文档，步骤如下: 1.单击“开始”，指向“程序”，指向“附件”，单击“记事本”，打开“记事本”窗口。 2.键入几行文字，然后在“文件”菜单中，单击“打印”命令。如果能够打印测试文档，就是原来你使用进行打印的程序有问题，请重新安装程序。九、重新安装打印机驱动程序。有时，打印机驱动程序可能被损坏，从而引发无法打印文档的错误。我们可以重新安装合适的驱动程序，然后再打印。 1.在“打印机”窗口，右键单击打印机图标，再单击“删除”，然后单击“是”按钮。如果系统提示“删除这台打印机的专用文件”，请单击“是”按钮。如果系统提示删除默认打印机，请单击“确定”按钮。 2.在“打印机”窗口，双击“添加打印机”图标，打开“添加打印机向导”，单击“下一步”按钮，然后执行屏幕指令。十、确保端口与打印机电缆工作正常。进行了上述九项工作之后，以下的方法能够帮助你进一步发现问题之所在: 1.打印机电缆连接是否牢靠如果计算机直接与打印机相连，要确保连接计算机和打印机的电缆两端都插对插牢。如果使用打印切换设备，请先绕过切换设备，将打印机直接与计算机相连，然后尝试进行打印。 2.测试端口连接将打印机连接到另一个可用端口，重试打印文档，如果能够打印则表明原端口损坏。 3.测试打印机电缆换上另一根打印机电缆，然后重试打印文档，如果能够打印则表明原电缆

监控设备常见故障解决办法

1、云台的故障一个云台在使用后不久就运转不灵或根本不能转动，是云台常见故障。这种情况的出现除去产品质量的因素外，一般是以下各种原因造成的： (1)只允许将摄像机正装的云台，在使用时采用了吊装的方式。在这种情况下，吊装方式导致了云台运转负荷加大，故使用不久就会导致云台的传动机构损坏，甚至烧毁电机。 (2)摄像机及其防护罩等总重量超过云台的承重。特别是室外使用的云台，往往防护罩的重量过大，常会出现云台转不动(特别是垂直方向转不动)的问题。 (3)室外云台因环境温度过高、过低、防水、防冻措施不良而出现故障甚至损坏。 (4)距离过远时，操作键盘无法通过解码器对摄像机(包括镜头)和云台进行遥控。这主要是因为距离过远时，控制信号衰减太大，解码器接受到的控制信号太弱引起的。这时应该在一定的距离上加装中继盒以放大整形控制信号。 2、监视器的图像对比度太小，图像淡。这种现象如不是控制主机及监视器本身的问题，就是传输距离过远或视频传输线衰减太大。在这种情况下，应加入线路放大和补偿的装置。 3、图像清晰度不高、细节部分丢失、严重时会出现彩色信号丢失或色饱和度过小。这是由于图像信号的高频端损失过大，以3MHz以上频率的信号基本丢失造成的。这种情况或因传输距离过远，而中间又无放大补偿装置；或因视频传输电缆分布电容过大；或因传输环节中在传输线的芯线与屏蔽线间出现了集中分布的等效电容造成的。 4、色调失真。这是在远距离的视频基带传输方式下容易出现的故障现象。主要原因是由传输线引起的信号高频段移过大而造成的。这种情况应加相位补偿器。 5、操作键盘失灵。这种现象在检查连线无问题时，基本上可确定为操作键盘"死机"造成的。键盘的操作使用说明上，一般都有解决"死机"的方法，便如"整机复位"等方式，可用此方法解决。如无法解决，就可能是键盘本身损坏了。 6、主机对图像的切换不干净。这种故障现象的表现是在选切后的画面上，叠加有其它画面的干扰，或有其它图像的行同步信号的干扰。这是因为主机制矩阵切换开关质量不良，达到图像之间隔离度的要求所造成的。如果采用的是射频传输系统，也可能是系统的交扰调制和相互调制过大而造成的。一个大型的、与防盗报警联动运行的电视监控系统，是一个技术含量高、构成复杂的系统。各种故障现象虽然都有可能出现，但只要把好所选用的设备和器材的质量关，严格按标准和规范施工，一般是不会出现大问题的。即使出现了，只要冷静分析和思考，不盲目地大拆大卸，是会较快解决问题的。 7、视频传输中，最常见的故障现象表现在监视器的画面上出现一条黑杠或白杠，并且或向上或向下慢慢滚动。要分清是电源的问题还是地环路的问题，一种简易的方法是，在控制主机上，就近只接入一台电源没有问题的摄像机输出信号，如果在监视器上没有出现上述的干扰现象，则说明控制主机无问题。接下来可用一台便携式监视器就近接在前端摄像机的视频输出端，并逐个检查每台摄像机。如有，则进行处理。如无，则干扰是由地环路等其它原因造成的。二是在没有报警接口箱的情况时，可自行设计加工信号扩展设备或驱动设备。 8、监视器上出现木纹状的干扰。这种干扰的出现，轻微时不会淹没正常图像，而严重时图像就无法观看了(甚至破坏同步)。这种故障现象产生的原因较多也较复杂。大致有如下几种原因：
