复印机维修资料大全

第一、复印机出现故障后的检查与维修步骤:复印机出现故障后,总有一种是主要的故障,抓住这个主要的故障进行分析,即可找到故障原因和排除的方法,我们一般可通过以下几条途径来查出故障的原因并排除之。
检修时应遵循先易后难的原则并逐步缩小范围,最后集中于某一点上。
一、了解情况维修机器前首先应认真询问操作者有关情况,如机器使用了多久,上次维修(保养)是在什么时间,维修(保养)效果如何,此次是什么情况下出现的故障。
还要认真翻阅机器有关维修记录,注意近期更换过哪些部件和消耗材料,有哪些到了使用期限而仍未更换过的零部件。
二、检查机器情况了解清楚以后,即可对机器进行全面检查,除了机内短路、打火等故障外,都可接通机器电源,复印几张,以便根据其效果进行进一步分析。
对于操作者提供的故障现象应特别注意,并在试机时细心观察。
三、准备工具在对机器进行检查的基础上,一般可对故障现象有个大致的了解,即可知道维修时需要哪些常用的专用工具,准备好将要使用的工具和材料后即可进行检查维修工作。
四、机器故障自检目前绝大多数复印机都装有彩色液晶显示面板,并设有卡纸等故障自检功能,一旦机器某一部件失灵或损坏,都能以字母数字告诉操作者。
比较常见的是故障代码,如NP系列复印机的故障代码为“E0~E8等,理光系列则以”U“加数字为代码,这些代码一出现分别表示印刷电路板,传感器、开关、接插件等工作状态异常,需要进行调整或更换。
作为机器的使用者,见到这些故障代码,应立即停机,关掉电源,请维修人员进行检修。
如果是自己修理,则必须找到与所使用机器型号相同的维修手册或维修说明书,在书中查到故障代码所表示的内容,再检查相应的零部件、电路板或电子元件。
第二、常见“共性”故障的检修由于复印机的种类和型号繁多,各制造厂生产的复印机各不相同,即使是同一个生产厂家生产的不同型号复印机也不完全一样。
因而在使用中所出现的故障现象还是有一些差别,这里仅对共性的、一般常见的故障及其成因和排除方法加以介绍。

分享复印机维修资料(Share copier maintenance materials)Share copier maintenance materialsAnalysis of common troubles in copying machine1 fault fault phenomenon: a Ricoh FT-4495 copier toner, recently because, replace the toner, soon no powder lights still bright, suggesting that toner is not enough, the main motor idling stop, can not copy.Fault analysis and Troubleshooting: according to the fault phenomenon, it is estimated that the toner cartridge is not installed in place, resulting in reloading toner cartridges, and check the toner amount is correct, the boot to try again, the failure is still. Open the front cover and observe the transmission of the powder feeding mechanism. It is found that the rotating powder feeding roller gear can drive the driving wheel and the stirring gear to rotate, indicating that the fault appears on the driving part of the stirring gear to the toner box. Remove the toner cartridge, toner cartridge between found gear broken and powder stirring gear, resulting in the toner powder stirring roller does not rotate, the toner cartridge for powder, the machine does not work, no powder toner cartridge to retrieve the original, will pour into the original toner cartridge, ink cartridge reloading, troubleshooting.Summary: when you change the toner cartridge, you must first gently shake the new box, so that toner distribution evenly, and turn the powder roller, so that it is flexible rotation, no dead center, you can install. Otherwise, will cause a stir roller gear broken phenomenon, causing unnecessary losses. Theworking process of the copierThe working process of the copier mainly consists of the following parts: (in the order of copying)Charging parts (high voltage generator, electrode rack, motor wire)Bring a uniform charge onto the surface of the drum.Exposure unit (scanning exposure lamp, reflector, lens)A reversal potential image is formed on the surface of the photosensitive drum according to the original image. (the previous chapter has already explained)Developing parts (developing device, high voltage generator)The latent latent image of the drum surface is converted into a toner image. (the previous chapter has already explained)Feeding parts (motors, paper wheels)The motor drives the paper wheel to feed the copy paper into the machine and prepares the ink transfer on the surface of the drum to the paper for the next step.Transfer parts (high voltage generator, electrode rack, motor wire)By transferring the electrode, the surface of the copy paperis uniformly charged with the charge of the toner, and the toner image on the photosensitive drum is transferred to the copy paper.Separation unit (high voltage generator, electrode rack, motor wire)Because the surface of the copy paper and the photosensitive drum are all charged and the polarity is reversed, the copy paper is difficult to separate from the photosensitive drum during the copying process. Therefore, separate measures should be taken to separate the copy paper from the drum. Earlier copiers were mechanically separated but easy to jam; current copiers were electrically separated. The separation current contains high frequency AC and fixed DC components.Cleaning parts (cleaner)Clean the residual toner on the surface of the sensitive drum and prepare for the next copy. It is impossible for all copiers to transfer the toner on the drum surface to the copy paper by transfer. Therefore, the drum surface has residual toner, not clean, it will affect the quality of the copy later.Fixing parts (fixing heat sticks, pressure bars, heaters)The toner image on the copy paper is fixed on the copy paper by fixing,So as to keep it. If the image is not touched, the image on the copy paper falls off. (so fixing requires a certain amount oftemperature and pressure.)The process of copying also involves many auxiliary processes:Power out unit (full exposure light)Remove the residual potential on the surface of the photosensitive drum and prepare for subsequent copying. Otherwise, the copy will contain a residual image or bottom ash.Edge deleting parts (such as inter image side lights)The copy has the front, front and rear sides, back ends, or narrow portions of the blank, so the surface potential of the unnecessary photosensitive drum needs to be removed by using an image like edge elimination lamp.Copier daily usage skillsDigital copier, compound machine office in small and medium-sized enterprises, are used frequently, and sometimes need to purchase the machine or buy supplies, which is a problem we procurement staff, how to choose the suitable company machine, how to buy genuine supplies and so on. Today, I give you the whole is a more comprehensive information, there are daily use skills, but also how to buy supplies and machines of some experts point of view inside. We hope to have some help to the daily office.Troubleshooting and analysis troubleshooting experience for copiersCopier occasional jam is not a fault, but if the frequent jam, you need to check and repair. First of all, it should be clear where the paper jam is for paper parts, paper parts, or fixing parts, of course, the three parts such as parts are obviously damaged, can be replaced. But in many cases, the entire transmission mechanism without any obvious damage to the parts, but also without any obstacles, but frequently jam paper, not only affect the efficiency of work, but also affect the working mood of the operator. For maintenance personnel, sometimes several factors are often intertwined to influence diagnosis.Copier1., paper for paper jam: this part of the cardboard, involving many aspects, first of all should check whether the used paper is standard (such as paper weight, size, dry degree), test machine use standard paper. Cartons are irregular and cause paper jams. You can try to put only a few sheets of paper box, then paper, if not rub or not in place, it can determine a paper rubbing wheel or a paper rubbing clutch problem; if a paper rubbing paper in place, but can't move on, it is estimated on roll sliding or para clutch failure caused by. For some models, the paper appears askew and may be caused by unequal clamping forces on both sides of the carton. In addition, many operators in the carton box, the force is too large, resulting in a few cartons of paper from the claws, it will inevitably cause cardboard.The 2. part: such as cardboard paper in this area often jams and should aid in the door switch plate (a tool), carefullyobserve the site operation, excluding factors are in round conveyor belt and guide, should check the separation mechanism. Because of the different types of copiers, the separation methods should be differentiated. At present, there are three kinds of separation models in China, such as vacuum separation, separation, separation and charge separation. Specific inspection and maintenance methods will not be repeated here.3. fixing parts cardboard: when the fixing roller separation claw for a long time after use,The end of its blunt or small spring fatigue failure, will cause cardboard. For some models, the paper feed roller after a long time to use serious wear and tear, will also frequently jam. As for the fixing roll, the jam caused by serious scaling is common in the general machine type.Buy Copiers how to strengthen the authenticity of supplies?Don't pay attention to the price to buy the copier, some informal copier dealers, in order to earn greater profits, even the machine modification or replacement of fake supplies, this not only affects the service life of the copier, copier will also increase the failure rate. Now we will provide you with several items to buy Copiers attention:First, see if the copier has been opened or sealed, and the original machines are sealed by single channel.Second, the original copier toner cartridges are wrapped in zinc skin, the packaging is neat.Third, buy fake toner copier, copy effect, black and white depth and ordinary copiers, the effect is much worse.Fourth, the use of false toner, there will be a special smell.Fifth copier copy number, and technical parameters are different, this is the customer is not easy to note, but also the most important way of identification.Several problems should be paid attention to when buying copiersNowadays, there are many kinds of brands in the copier market, and the functions are more and more. What brand of copiers should a small and medium-sized enterprise choose?This is also from several points of view: first, according to the use of customers, divided into low, medium, high-speed copiers. Each month load capacity is different, generally 10 thousand within the choice of low speed machine; 2--5 million to select medium speed copier, even if the user dosage is larger, also can meet the needs. 5-10 must buy high-speed machines. Second, function, choose a copier, must look at the copier function is not able to meet your use, such as now can add, print, scan, fax and other functions. Copier life expectancy of 5-8 years on average, but also consider the future increase in workload can meet, or provincial level and so on. Third, the copier consumables are satisfactory to you? Some copiers exist machines, cheap, but the latter use cost is amazing, this is generally based on the actual use of customers.About customer service service these big brands are similar, Canon, SHARP, Toshiba Ricoh, is a year of free home repair, but KYOCERA copier is three years free on-site maintenance, so once again remind you, buy Copiers to ask the copier warranty time.Method for resetting special fault code of SHARP copierSpecial fault code 700/800 series of SHARP copiers are mainly HX (H1 H8, heat roller fixing device fault), Lx (L1-L6, micro switch / photoelectric switch fault, Ux (U1U2), low battery voltage or data transmission fault) and Pl (exposure lamp temperature fuse abnormal). Among them, U1 used the command "13" reset, other special instructions for fault code "14" reset.SHARP 1000/2000 series copier special fault code, mainly HX (H2-H4, hot roller fuser fault) and U2 (memory read and write failure), which U2 with instructions "16" reset,Other special fault codes are reset by instruction 14.SHARP 7000/8000 series copier special fault code, mainly HX (H3, H4, hot roller fuser fault) and U1 (battery voltage is low). The U1 is reset by the instruction "13", and the H3 H4 is reset by instruction "14". The sequence of the reset operation is shown in the figureIn addition, a special fault code for SHARP Z60 copier with U (motherboard battery low), L (micro switch fault) and H (failure of hot roll fuser (F), fixing the lamp or temperaturefuse) said, with "1" reset command. Reset, in order to press the clear key, duplicate keys, (addend key), (digital subtraction key) key "1" and the copy button:(1) the key should be pressed within 5 seconds:(2) SHARP, 750, 770, 771, 780, 781, 825 and other copiers press duplicate keys, other copiers press the pause button;(3) at this time all the display on the operating board disappears, the main motor stops rotating, the copier is ready to receive instructions (when the main motor rotates, copy)The machine does not accept instructions;(4) SHARP 1000/2000 series 1016, 1020, SHARP copier includes 1025, 1116, 2014, 2020, 2022, 2027, 2040, 2114, 2214 SHARP 7000/8000 series copiers copiers; including SHARP 7320, 7370, 7700, 7750, 7800, 7850, 8570, 8870 copiers.Inspection and maintenance of paper jam in copierIt is believed that every person who has used the copier will experience the problem of paper jam. It should be said that the occasional paper jam is unavoidable in the process of copying, but if the paper is often jammed, it shows that the machine is out of order and needs to be repaired. Factors causing jamA lot of, mainly has following several factors;1. carton cardboard: (1) carton (2) paper rubbed parts2. paper road paperboard: (1) aligning roll; (2) separating mechanism; (3) paper path sensor; (4) separating claw; (5) fixing roller;3. automatic pagination causes jamThe 4. scan component causes jam5. machine short circuit causes jam6. improper handling, resulting in cardboardInspection and maintenance of concrete jam:The L. card in the transmission fault causes and elimination methods in the paper:(1) the paper feed clutch is out of control. Adjust and change the paper feed clutch;(2) there is a foreign matter in the feeder. Foreign body removal;(3) the paper is partial to block cold. Clear the blocked paper;2. cards in reason and elimination method of fault separator:(1) separation, loosening, falling or breaking, or air suction and separation, and insufficient suction force, so that the paper sticks on the drum or enters the cleaning box, and theseparation belt is replaced. Adjust the air quantity and position;(2) the paper goes astray. Trouble out of paper offset.3. causes and troubleshooting of frequently jammed paper cleaner:Some contact with the cleaner copier drum part is provided with a grid, it is made of plastics, and prevent the copy paper into the role of cleaner, normal copy, even if there are cards in this part, the paper is also very easy to remove,But the gate is damaged, the paper will enter the cleaner, tight to remove. The cleaner shall then be removed from the photosensitive drum and removed from the machine as necessary and removed from the cardboard for repair or replacement of the grid bar,Ability to continue.Laser printer maintenance manualThe widespread application of laser printers in enterprises and companies is accompanied by the maintenance problems of printers when they are in trouble. This paper mainly aims at the common faults of EPSON laser printers. Including maintenance essentials, common models of the fault code, specific printer failures, etc., hoping to maintain the laser printer when you help.Quick laser printer maintenance and fault codeLaser printer is a kind of highly automatic computer output equipment integrating light, machine and electricity. It is mainly composed of laser scanning system, mechanical drive system and imaging medium with the toner and cartridge, as well as the circuit part, the conversion part and heating part. Its working principle is the first charging unit inside the machine to the cartridge plus negative charge, then the board according to the laser laser emission from the host signal transmitted over the control, the laser shines on the cartridge surface will leave an electrostatic image in the toner in the toner chamber surface, the toner is adsorbed to the toner image formed on the surface of the electrostatic toner image, when the toner cartridge the surface and send the paper contact image transfer to the paper, by the end of the paper is heated so that the image permanently stored in paper. The printing process can be divided into 7 steps: charging, exposure, imaging, transfer, separation, fixing and cleaning.When a fault occurs, to the exclusion of other improper operation and material is not suitable for the problem, do not rush to the dismantling of printer, first turn off the power switch, such as printer temperature down after a reboot, to observe whether the fault is cleared if the fault phenomenon still into maintenance. Also note that many components of the laser printer, such as the drum assembly, the fixing assembly, and the paper rubbing wheel, are part of the consumer and need to be replaced regularly.Laser printer repair failure: no electricity output, output,cardboard, blank black, pale and output when writing vertical stripes, Liby printing paper, printing paper on the black side repeated dirt1, laser printer preheating more than 2min or amorphous, text fall off.One is to consider whether the indoor temperature above 20 degrees celsius;The two is to check if the thermistor is out of contact or invalid;Three is to see whether the voltage reaches 220V;Four is to see the paper, toner is too dampWet, etc..2, cardboardFirst, check the size of the paper is appropriate, the paper is too thick, too thin, paper wet or volumeSong, will produce jam phenomenon;Two is coated paper can not be used for ordinary laser printers;The three is to check the separation of the laser printer claw is worn, need to change.3, such as printed on the part or all of the word is not clear, toner uneven uneven and so on.The reason for this failure is the amount of toner cartridge is insufficient, need to supplement.4, appear on the print black or underworld, and change paper still appear in the same position.The cause of the malfunction is the damage of the OPC drum.5. If there is a horizontal stripe on the print, it will appear in the same position after changing paper,It shows the need to change the squeegee6. If there is a longitudinal stripe on the print, it will appear in the same position after changing the paper,The magnetic roller on the powder storage box is damaged and needs to be replaced.7, in the printing piece, the big character has the zigzag shape, the writing appears a straight line, lacks the pen to delimit,Note that the six corner mirror or F theta objective has dust to be cleaned(this problem should be dealt with by professional and technical personnel).Note 8, replacement of toner:First, the powder feeding bin and powder storage bin should be cleaned;Two, after the toner, the powder in the toner warehouse parallel shake, clockwise rotation of the teeth by handThe number of rings, so that toner evenly attached to the magnetic roller, to ensure uniform toner.9, if the replacement toner after writing ink irregularity or powder leakage phenomenon, print a few after theBarrier or unresolved, at this time we must first consider whether the wet toner, followed by considering powder deliveryIs the toner in the bin too full?.10, laser printer in the process of hair sample, if the host's monitor appears "laser printer"When the word "power off" and "peripheral equipment is not ready" is mainly connected from the signal lineFind solution.11, if the laser printer self-test, the pattern is all black, no self-test lines. HostThe monitor appears "IACK", which indicates that the videointerface card is out of order.EPSON laser printer maintenance EssentialsFault diagnosis program EPSON laser printer will be built according to different types of machine fault code is displayed in a different way when a fault occurs, the maintenance engineer can estimate the fault code meaning of fault location, refer to the corresponding solution models according to the maintenance manual manual maintenance.EPSON laser printer fault code display is divided into the following 3 types:1. screen display type, its fault code through the printer control panel on the LCD screen display. Representative models are EPL-N1610, EPL-N2120 and so on;The 2. indicator display type, its fault code, is displayed by the indicator light on the printer control panel or different combinations of flashes or lights. Representative models are: EPL-5900, EPL-6100 and so on;3. computer screen display type, when the fault occurs, by pressing the key combination on the keyboard, the fault code will be displayed on the computer screen associated with the printer. Representative models are: EPL-6100L, EPL-1220 and so on.Printer stepping motor maintenanceThe manufacturing accuracy of printer stepping motor is higher, and the main fault is non feed. The following methods can be used to judge whether the motor is damaged or not.(1) measure the resistance according to the resistance value on the step motor. The stepper motor is divided into two winding, two winding structure is the same as that of the other end of each winding center symmetric resistance are equal, and consistent with the marked resistance, different order of different motor wire.When measuring the first use of multimeter will be divided into two groups (each lead wire connected to a group), and then find out the method to measure the resistance center tap end of each group, the center end to the other ends of resistance and resistance value consistent annotation. If the resistance is asymmetric or different from the indicated resistance, the motor may be damaged.(2) test the power supply voltage on the stepper motor (or the working voltage of the motor in the circuit). If the motor is not marked, start using a lower voltage,Then gradually increase the voltage to test. One end of the power supply (both positive and negative) connected to a winding center end, the other end of the power supply at both ends of the winding alternately touching (note the touch time not too long), the step motor step by step rotation, and each step should be equally powerful, or that the motor is damaged. Inspection should be noted that if the stepper motor winding serious short-circuit test must not be, otherwise it will burnout power.(3) some stepper motors have two identical windings, but there is no center tap end. When measuring, you can measure whether the two winding resistance is equal, and should be consistent with the motor tagging, and then use the power supply test. During the test, the power poles are alternately touching each end of each winding. At this point, the stepper motor should be rotated step by step and equally powerful, otherwise the motor will be damaged. It should be pointed out that when the stepper motor is damaged, the stepper motor drive circuit should be checked for damage.。

复印机维修技术资料(全面)

第一章复印机的工作原理一、复印机的种类1.根据复印机工作原理的不同,复印机可分为模拟复印机和数码复印机两种。
2.根据复印的速度不同,复印机可分为低速、中速和高速三种(每分钟复印A4幅面的张数来决定)。
复印机每分钟可复印A4幅面的文件10-30份,中速复印机每分钟可复印30-60份,高速复印机每分钟可复印60份以上。
3.根据复印的幅面不同,复印机可分为普及型和工程复印机两种。
一般我们在普通的办公场所看到的复印机均为普及型,也就是复印的幅面大小为A3-A5。
如果需要复印更大幅面的文档(如:工程图纸等),则需使用工程复印机进行复印机,这些工程复印机复印的幅面大小为A2-A0,甚至更大,不过其价格也非常昂贵。
4.根据复印机使用纸张,复印机可分为特殊纸复印机及普通纸复印机。
特殊纸一般指可感光的感光纸,而普通纸是指普遍使用的复印机。
5.根据复印机显影方式不同,复印机可分为单组份和双组份两种。
6.根据复印机复印的颜色不同,复印机可分为单色、多色及彩色复印机三种一、根据复印机工作原理的不同,复印机可分为模拟复印机和数码复印机两种。
1、模拟复印机的工作原理模拟复印机的工作原理是:通过曝光、扫描方式将原稿的光学模拟图像通过光学系统(如:镜头、镜子)直接投射到已被充电的感光鼓上,产生静电潜像,再经过显影、转印、定影等步骤,完成整个复印过程。
2、数码复印机的工作原理首先通过CCD(电荷耦合器件)传感器对通过曝光、扫描产生的原稿的光学模拟图像信号进行光电转换,然后将经过数字技术处理的图像数码信号输入到激光调制器,调制后的激光束对被充电的感光鼓进行扫描,在感光鼓上产生静电潜像,图像处理设备(存储器)对诸如图像模式、放大、图像重迭等作数码处理后,再经过显影、转印、定影等步骤,完成整个复印过程。
数码复印机基本上相当于把扫描仪和激光打印机的功能融合在一起了。
复印机的工作原理主要包括以下三个基本的原理:静电原理电荷有正负两种极性,所谓静电原理是指同性电荷相互排斥;异性电荷相互吸引。

故障原因与排除方法: 复印机的搓纸轮大多数靠电磁线圈的动作来控制。检查时需使机器处于有纸状态,可用 透明胶纸将检测有无纸盒的开关粘住,使无纸信号不出现,将一小块纸放在检测纸盒的光电 传感器上,按下开始复印键后,大约 1 ̄2 秒钟后,控制搓纸轮的电磁线圈的衔铁应有吸台动 作,如果无此动作,则应检查电磁线圈与线路板间的连线接触是否良好。如果有此动作,则 应考虑搓纸离合器内的弹簧是否损坏;生锈,必要时应更换离合器。
鼓。 (5) 墨粉颗粒太大,显影图像表面粗糙,造成分辨率下降。如出现由于图像发黑而造
成不清 晰,应考虑可能是显影器下墨粉太多。
13. 复印件图像浓度不均匀 复印件复印出的图像不均匀分两种情况:一种是有规则的不均匀;另一种是无规则的
不均匀。 (1) 出现有规则的不均匀故障原因与排除方法: ① 电极丝与感光鼓不平行,造成转印电晕不均匀。 ② 曝光窄缝两边不平行,造成曝光量不均匀。 ③ 机内有乱反射光的干扰。 ④ 显影辊与感光鼓表面不平行;液干法显影中挤料辊与感光鼓不平行;显影间隙两
端不等, 均会造成上述的不均匀。
(2) 出现无规则的不均匀故障原因与排除方法: ① 复印纸局部受潮。 ② 曝光灯管、稿台玻璃等光学部件受污染,影响光反射和透射的均匀。 ③ 充电和转印电极丝污染,造成放电的不均匀。为防止此种情况,应经常保持电极
清洁使放 电均匀。 ④ 采用热辊定影的机器,由于加热辊表面橡胶老化脱落、有划痕,或定影清洁刮板
4. 复印后复印件出现底灰 复印件上有深度不等的底灰,是静电复印机中一种常见的现象,而且是一个难于解决的
问题,复印件上有无底灰存在是鉴别其质量好坏的重要标志之一。 故障原因及排除方法: (1) 曝光不足,原因包括曝光灯老化,照度下降;光蓬开得太小,曝光量小。调整曝光
电压、光缝或更换曝光灯; (2) 原稿反差太小; (3) 复印纸受潮; (4) 显影偏压过低或无显影偏压;调整显影偏压、检修显影偏压电路。 (5) 第二供纸行程开关是否良好,位置是否合适,有否积粉脏污; (6) 第二供纸离合器是否良好; (7) 扫描台行程开关中的对位起始微动开关或传感器是否失效; (8) 纸路当中是否脏污、有异物等。
4.2 常见“共性”故障的检修
由于复印机的种类和型号繁多,各制造厂生产的复印机各不相同,即使是同一个生产厂 家生产的不同型号复印机也不完全一样。因而在使用中所出现的故障现象还是有一些差别, 这里仅对共性的、一般常见的故障及其成因和排除方法加以介绍。
本节中所列举的故障,对于各种复印机并非一律如此,即使同一故障在不同的类型的机 器中,其成因可能并不相同。因此,这里更重要的是提供方法和思路。(有些故障只要找到 成因即知排除方法,因此这些故障的排除方法就不再赘述。)
⑨ 复印绿键按下后,第一步供纸不良 故障原因及排除方法: 首先观察搓纸是否转?如果转动良好而不能搓纸,则检查:
a. 搓纸轮是否脏污、老化、摩擦力下降,如果脏污,可用浓酒精擦洗;如果磨秃老化, 可更
换新搓纸轮。也可采用土办法:剪一段橡胶指套,套在搓纸轮上,实践证明,这是解 决搓纸轮摩擦力的有效方法。 b. 顶纸板弹簧顶力是否下降,如果下降,就进行调整。
