Chapter2.Safety information

This chapter contains the safety information that you need to be familiar with before servicing a computer.

General safety

Follow these rules to ensure general safety:

?Keep the areas around the computer clear and clean during and after maintenance.

?When lifting any heavy object:

1.Ensure you can stand safely without slipping.

2.Distribute the weight of the object equally across both feet.

3.Lift slowly.Never move suddenly or twist when you attempt to lift.

4.Lift by standing or by pushing up with your leg muscles;this action removes the strain from the

muscles in your back.

Do not attempt to lift any objects that weigh more than16kg(35lb)or objects that you think are

too heavy for you.

?Do not perform any action that would create a hazard for the customer,or would make the computer unsafe.

?Before you start the computer,ensure that other service representatives and customer personnel are not in a position that would create a hazard for them.

?Place removed covers and other parts in a safe place,away from all personnel,while you are servicing the computer.

?Keep your tool case away from areas that people may walk through to ensure no-one trips over it.

?Do not wear loose clothing that can be trapped in the moving parts of a machine.Ensure that your sleeves are fastened or rolled up above your elbows.If your hair is long,tie or fasten it back.

?Insert the ends of your necktie or scarf inside clothing or fasten it with a non-conductive clip, approximately8centimeters(3inches)from the end.

?Do not wear jewelry,chains,metal-frame eyeglasses,or metal fasteners for your clothing.

Remember:Metal objects are good electrical conductors.

?Wear safety glasses when you are:hammering,drilling soldering,cutting wire,attaching springs,using solvents,or working in any other conditions that might be hazardous to your eyes.

?After service,reinstall all safety shields,guards,labels,and ground wires.Replace any safety device that is worn or defective.

?Reattach all covers correctly before returning the computer to the customer.

Electrical safety

CAUTION:

Electrical current from power,telephone,and communication cables can be hazardous.To avoid personal injury or equipment damage,disconnect any attached power cords,telecommunication cables,network cables,and modem cables before you open the computer covers,unless instructed otherwise in the installation and configuration procedures.

?Copyright Lenovo20173

Observe the following rules when working on electrical equipment.

Important:Use only approved tools and test equipment.Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.Many customers have rubber floor mats near their equipment that contain small conductive fibers to decrease electrostatic discharge.?Find the room emergency power-off(EPO)switch,disconnecting switch,or electrical outlet.If an electrical accident occurs,you can then operate the switch or unplug the power cord quickly.

?Do not work alone under hazardous conditions or near equipment that has hazardous voltages.?Disconnect all power before:

–Performing a mechanical inspection

–Working near power supplies

–Removing or installing Field Replaceable Units(FRUs)

?Before you start to work on the computer,unplug the power cord.If you cannot unplug it,ask the customer to power-off the electrical outlet that supplies power to the machine and to lock the electrical outlet in the off position.

?If you need to work on a computer that has exposed electrical circuits,observe the following precautions:–Ensure that another person,familiar with the power-off controls,is near you.

Remember:Another person must be there to switch off the power,if necessary.

–Use only one hand when working with powered-on electrical equipment;keep the other hand in your pocket or behind your back.

Remember:There must be a complete circuit to cause electrical shock.By observing the above rule, you may prevent a current from passing through your body.

–When using a tester,set the controls correctly and use the approved probe leads and accessories for that tester.

–Stand on suitable rubber mats(obtained locally,if necessary)to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages;these instructions are in the safety sections of the maintenance https://www.wendangku.net/doc/0e2718022.html,e extreme care when measuring high voltages.?Regularly inspect and maintain your electrical hand tools to ensure they are safe to use.

?Do not use worn or broken tools and testers.

?Never assume that power has been disconnected from a circuit.First,check that it has been powered off.?Always look carefully for possible hazards in your work area.Examples of these hazards are wet floors, non-grounded power extension cables,conditions that may cause or allow power surges,and missing safety grounds.

?Do not touch live electrical circuits with the reflective surface of a plastic dental mirror.This surface is conductive,and touching a live circuit can cause personal injury and damage to the computer.

?Do not service the following parts with the power on when they are removed from their normal operating positions in a computer:

–Power supply units

–Pumps

–Blowers and fans

–Motor generators

and similar units.(This practice ensures correct grounding of the units.)

?If an electrical accident occurs:

–Use caution;do not become a victim yourself.

4ideacentre All-In-One520(22&24inch)Computer Hardware Maintenance Manual

–Switch off power.

–Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potential hazards posed by these products. Each computer,as it was designed and built,had required safety items installed to protect users and service personnel from injury.This guide addresses only those items.However,good judgment should be used to identify potential safety hazards due to attachment of features or options not covered by this inspection guide.

If any hazards are present,you must determine how serious the apparent hazard could be and whether you can continue without first resolving the problem.

Consider the following items and the safety hazards they present:

?Electrical hazards,especially primary power(primary voltage on the frame can cause serious or fatal electrical shock).

?Explosive hazards,such as a damaged CRT face or bulging capacitor

?Mechanical hazards,such as loose or missing hardware

The guide consists of a series of steps presented as a checklist.Begin the checks with the power off,and the power cord disconnected.

Checklist:

1.Check exterior covers for damage(loose,broken,or sharp edges).

2.Power-off the computer.Disconnect the power cord.

3.Check the power cord for:

a.A third-wire ground connector in good https://www.wendangku.net/doc/0e2718022.html,e a meter to measure third-wire ground

continuity for0.1ohm or less between the external ground pin and frame ground.

b.The power cord should be the appropriate type as specified in the parts listings.

c.Insulation must not be frayed or worn.

4.Remove the cover.

5.Check for any obvious https://www.wendangku.net/doc/0e2718022.html,e good judgment as to the safety of any alterations.

6.Check inside the unit for any obvious hazards,such as metal filings,contamination,water or other

liquids,or signs of fire or smoke damage.

7.Check for worn,frayed,or pinched cables.

8.Check that the power-supply cover fasteners(screws or rivets)have not been removed or tampered with. Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits(ICs)should be considered sensitive to electrostatic discharge(ESD).ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the computer,the part,the work mat,and the person handling the part are all at the same charge.

Notes:

https://www.wendangku.net/doc/0e2718022.html,e product-specific ESD procedures when they exceed the requirements noted here.

2.Make sure that the ESD protective devices you use have been certified(ISO9000)as fully effective. When handling ESD-sensitive parts:

Chapter2.Safety information5

?Keep the parts in protective packages until they are inserted into the product.

?Avoid contact with other people while handling the part.

?Wear a grounded wrist strap against your skin to eliminate static on your body.

?Prevent the part from touching your clothing.Most clothing is insulative and retains a charge even when you are wearing a wrist strap.

?Use the black side of a grounded work mat to provide a static-free work surface.The mat is especially useful when handling ESD-sensitive devices.

?Select a grounding system,such as those listed below,to provide protection that meets the specific service requirement.

Note:The use of a grounding system is desirable but not required to protect against ESD damage.

–Attach the ESD ground clip to any frame ground,ground braid,or green-wire ground.

–Use an ESD common ground or reference point when working on a double-insulated or battery-operated system.You can use coax or connector-outside shells on these systems.

–Use the round ground-prong of the AC plug on AC-operated computers.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function.Proper grounding of the electrical outlet can be verified by a certified electrician.

爱普生打印机保养与维修 爱普生打印机保养与维修 爱普生打印机冬季保养专题 -------------------------------------------------------------------------------- 主要原因分析: 打印机所处的环境温度过低:冬季寒冷干燥,打印机工作在干燥和温度比较低的环境中,会使打印机 字车导轨上的润滑油的润滑效果减弱,字车在导轨上移动时摩擦阻力增大,易出现打印头撞击的现象; 灰尘过多:冬季风沙较大,过多的尘土落入打印机,导致字车在导轨上摩擦阻力增大,出现打印头撞 击的现象; 打印机内部有异物:特别是对于新购买的打印机,用户对打印机不是很了解,包装材料没有完全被去 除掉,最容易出现这种现象。 解决办法: 打印机工作的环境温度和湿度保持在:温度在10-35℃之间;湿度:20~80% (相对) 清除打印机内部异物:对于新购买的机器请一定按《用户手册》的要求去除保护材料。当打印机卡纸 时,请严格按《用户手册》的要求清除卡纸。 EPSON喷墨打印机如何区分堵头与断线 -------------------------------------------------------------------------------- 使用EPSON喷墨打印机时,应养成经常做喷嘴检查的习惯,尤其对于不天天使用的用户,可避免因为 断线引起的打印稿报废,免得无谓的时间和墨水浪费。

EPSON打印机喷嘴检查所打的斜条图案中的每一条小横线代表一个喷嘴,当有缺线时,好些人以为是 堵头了。其实绝大部分情况仅仅是发生断线,产生断线的原因很多,如换墨盒、加墨水、长期不用等等, 通常能通过做"打印头清洗"即可解决。 如何判断是堵头了还是断线:若每次清洗后,图案中缺线位置没有变化,总是在固定的位置缺线,表 明是该喷嘴堵住了。若缺线的位置是变化的,则不是堵头而是断线。在更换墨盒时(或加墨水后)有断线 是正常的。一般清洗一、二次全好,而且是每次清洗断线都会减少(注意:两次清洗时间最好间隔20分钟 以上)。使用中出现断线,如果越清洗断线越多,则是墨盒中的墨水没有了,这是应立即更换墨盒或填充 墨水。 EPSON系列打印机喷头的拆解与清洗 -------------------------------------------------------------------------------- EPSON公司的C4X(C41、C43等)系列喷打拥有一大批用户。如不经常使用,在空气干燥的地方尤其是北 方,打印头的墨水很可能发生干涸甚至喷孔被堵塞。在采用清洗打印头程序操作处理仍然无效的情况下, 只能考虑将打印头拆下来进行人工处理了。目前,网上流传着关于打印头暴力拆卸的文章,笔者认为这种 方法对于普通用户来说可能会造成非常严重的后果,本文将告诉读者如何正确拆卸打印机喷头。 准备工作是在联机状态下进行更换墨盒的操作,当打印头移动到轨道中间时即可拔掉电源,目的是为 了让打印头脱离喷头保护及锁定装置。

关于爱普生R230打印机进纸故障 及卡纸问题的解决办法 爱普生R230普遍存在的一个问题是:使用一段时间后打反面经常进纸困难,严重的时候,打正面也经常进不了纸,反复取放好几次才能打一张,上述故障有的新机子也有。 有同修说是搓纸轮不行。要换加强轮,并推荐更换佳能一款激光机搓纸轮。最近通过两台R230出现此故障后(其中一台是新的,刚买来就不能正常使用),经研究发现并不是搓纸轮本身的问题,而是机子自身设计有缺陷,简单分析如下: 其实是进纸器(放纸的结构)与机体本身的间隙稍微大了一点,也就说搓纸轮本身和主机之间间距稍微大了一点。因此同修建议换加强轮也能解决此问题,因为加强轮直径比原装搓纸轮稍微大一点。 具体的解决办法有二: 一、将机子拆开,取下安搓纸轮的轴后,取下搓纸轮上的塑料套,用封口胶在轮上缠几圈,再把塑料套安好,通过这样增大了搓纸轮直径解决了此问题。 二、放纸的结构里面推纸板下面的弹簧质量有问题,使用时间稍微长一点后变软了,推纸不到位,使主机上的搓纸轮卷不到纸。因此建议将推纸板下面的弹簧换成强度高一点的,或者拉长一点也暂时可以解决此问题。 另外,经使用发现,市场上卖的专供大陆的爱普生R230打印机(灰色外壳)上述故障比较普遍,有些机子不长时间就出现断线,有的新机就不好进纸;相反专供台湾的爱普生R230打印机(白色外壳)故障少些,好用的多,而且比灰色外壳的便宜约200~300元,建议如果打算买R230打印机,最好买白色外壳的。但需要找,不是每个商家都有。 关于EPSON R210,230打印机喷嘴检查正常,打印照片粗糙的问题? 我们自己用质量一般的墨水测试210打印机,打了600ML的墨水,打印照片就出问题了,因质量一般的墨水,它也不会堵头,就是墨水的流畅性不好,用一段时间在喷嘴周边部分的墨水就会沉淀,虽然喷嘴检查没事,但打印照片就有横纹和粗糙的现象.

联想m7020的维修资料

联想m7020的维修资料,研究了好一阵子,具体成果,首先发现他这一批打印机是日本鬼子兄弟公司制造的。并且和兄弟m7010一模一样,但是耗材就比兄弟价格高多了事先声明:要找到维修资料,然后按照它的说明用机器进入维修模式自动打印出4 页固件自定义代码,并且小心使用,本人对因此产生的任何后果不负责任(英文要强阿)。1、我的m7020已经用一个鼓芯打印兼复印了27599页了(虽然他自己说寿命只有12000页),从没有想过如何爱惜和保养所谓的鼓芯,什么都打,现在还完好无损,这是联想唯一让我欣慰的方面了。2、它的粉仓我用完后加粉,发现莱盛m7000的粉比鸟联想原装的还好用,我本身不是一个爱护机器的人,什么废粉我统统不管,直接加的。3、我研究了它的绝密维修资料,用机器自动打印出了固件开关自定义代码,他的鼓芯寿命其实和页数计数器相关联,等打印到12000页的时候就总提示更换鼓芯,或者让你无法工作,一查才知道鼓芯寿命已经为0%,没关系,在它的垃圾机器上两个键搞定(打开前盖子,选项——向上箭头),寿命又回到100%。4、用到20000页左右的时候,总提示鼓芯单元需要清洁,我清洁了N次也不可以。又开始研究固件开关代码,发现了WS30里面的一个第八位数的开关,这个开关控制着鼓芯需要清洁的自动提示,将它杀死——OK!继续照常使用,一切顺利。如果还不行,那是电晕丝已经附着了大量没有办法清洁掉的碳粉硬块,你可以看一下,发现电晕丝上面有好多小黑快,这可以使用纯环已酮用棉签直接擦拭,注意不要碰到塑料部分,因为环已酮可以溶解塑料,直到电晕丝特别发亮为止,但是注意不要用力,那玩意儿很容易断。5、可是不久又提示更换鼓芯,发现寿命又到了0%,气人!还是研究固件开关,发现了一个硒鼓自动报废的数字开关,继续杀死。这下好了,永远安心用下去,估计直到质量绝对不可以接受的时候我才考虑更换鼓芯,都没有打算过买它的原装鼓,因为他们抢钱啊——650元一根棍儿。6、我的粉仓用完以后加粉加满了,可还是提示碳粉用光,我借朋友的粉仓拿来一实验,发现可以用,我就又试着装回原来的,奇怪吗?就OK了。就开始研究,结果是:粉仓左边有一个白色拉杆,加完粉以后需要将拉杆按照弧线角度推到另外一侧,如果推不动就把三个螺丝拧下来,推过去后再装上,放入打印机,他就认为你换了一个新的粉仓。鼓芯深度划痕我很简单就可以修补,我毛绒玩具自己的办法如下(造成什么不良后果我可不负责):1、用大量脱脂棉粘酒精(不要用手接触,尽管他们一再强调不可以使用酒精或者化学溶剂),然后顺着鼓芯轴线方向擦拭,转几下擦几下,我一般擦几百下,直到特别光洁锃亮为止,这时候脱脂棉上已经附着了好多鼓芯感光介质。2、到了报废了该扔了,有一个最好的办法,也是最坏的办法,用环已酮(搞丝网印刷的都有)和食用油,按照2/%的比例擦拭鼓芯表面,切忌尽量两三遍就擦拭均匀,因为环已酮可以很快融化鼓芯表面,但是擦拭坏的几率非常高。 联想的M7020/M7030/M7120/M7130N/M3020/M3120/M3220机器全是日本鬼子兄弟公司制造的。并且和兄弟m7010一模一样,但是耗材就比兄弟价格高多了。 具体方法如下: 1、根据维修资料(M7020的维修手册WSW资料是错误的)进入维修模式。M7020:功能--启动--功能--上箭头,按完后,屏幕显示"MAINTENANCE 06" 2、按上箭头,调到"MAINTENANCE 11",再按“设定”,机器会自动打印出4页WSW代码。

联想打印机维修大全

故障一、打印机无法打印 故障现象:联想LJ2000P型激光打印机开机后没有反应或无法打印。 故障分析:引起此故障的可能原因有以下几种:1.打印机电源没有接通、打印机电源开关未打开、打印机数据电缆的连接不正确;2.打印机进纸盒中没有纸,打印机有卡纸,感光鼓组件有问题;3.应用程序有问题或存在病毒;4.硬盘剩余空间过小导致打印机不能打印或未将当前打印机设置为默认打印机;5.当前打印机已被设置为暂停打印;6.打印机驱动程序不合适以及配置不正确;7.BIOS中打印机端口未能打开;8.打印机驱动程序未正确安装或损坏;9.打印机硬件出现故障。 故障检修方法:首先对打印机电源及电缆的连接进行检查,没有发现问题,接下来对进出纸路及感光鼓和硬盘进行检查,都没有问题,然后用杀毒软件对进行杀毒处理也没有效果。选择“开始/设置/打印机”,检查当前使用的打印机图标有一黑色的小钩,说明该机已被设置了默认打印机。再作进一步检查,发现驱动程序的选择不正确。在应用软件中选择联想LJ2000P的正确驱动程序后,故障排除。 检修经验:在使用串口打印时,如果打印机上的串口开关位置及DIP开关设置的接口参数不正确的话也会出现这种故障。 故障二、频繁出现更换碳粉报警 故障现象:联想LJ6P激光打印机在碳粉还未完全用完时,即频繁进行更换碳粉报警。 故障分析:如果此时更换碳粉盒,就会有大量的碳粉被浪费。联想LJ6P激光打印机检测碳粉是否用完是采用光电传感器来实现,它根据碳粉的位置进行检测。只要对光电传感器进行屏蔽,就可以消除报警情况。 故障检修方法:拆开机盖,取出硒鼓,在碳粉盒附近找到光电传感器,将其感光端用黑色胶带封住即可不出现报警,在打印图文过浅或不能打印时,再更换碳粉盒。 故障三、打印文件时出现“Print Over-run”字符

一、 LQ-670K 不联机 故障分析: 1、 DOS 状态下进行针测试时,电脑未做任何错误提示,但打印机始终无反应; 2、打98 测试页,打印头会来回移动几下,之后发出边疆不断的报警声,电脑提示联机出错; 3、量并口插座CN1 的/STB,/ERR,/PE,BUSY,/ACK 等命令脚的信号均正常; 4、换联机线缆及电脑主机后,总是依旧; 5、确定是打印机主板总是了,可是主板到接口的信号均正常,那么问题就只可能出在输出接口上;通过一个个的比对测量,终于发现第一脚“/STB”端的簧片变形了,以致CN1 与联机线缆的接触不紧密,造成了不联机的故障; 6、在变形的簧片上镀上焊锡,使CN1 与联机线缆紧密联系,故障即被排除。 实例4:客户新购买的LQ630K,打印多层纸时,从后向前打印时卡纸。 故障原因:进纸传感器安装的角度不对略微偏前(设计问题),当纸打印到出口(进纸传感器)处将传感器翻起造成卡纸。 二、LQ-670K 打印的字符笔划歪歪扭扭。 故障分析: ⑴清洁字车组件,进行BI—D 调整,打印出的校准图样自始至终都是歪歪扭扭的; ⑵更换字车电机,字车组件(字车导轴,字车托架,油毡)后,故障依旧; ⑶更换机械后,打印正常。问题部位锁定在机械方面,可是字车部分的主要器件都已经换了,还有哪呢? ⑷试着更换字车同步带,清洁同步带轮子,上油。试打,故障依旧; ⑸更换整个色驱架及里面的齿轮且不装色带试打,故障依旧;机械部分好象已经没有东西可以换了,可问题依然存在! ⑹拿起机子的打印头看看,也不会很脏呀,只是打印头与色带接触的面已被磨的有点下陷了,拿了个新打印头更换后试打,问题终于解决了!

各种打印机维修大全

对于企业来说,管理和监控办公设备的往往是行政职员,这类职员又通常以女性为主,她们在面对打印机出现故障的时候通常束手无策。 那么出了故障怎么办,最捷径的办法就是给维修人员打电话,结果是维修人员顶着炎炎烈日,花费两小时坐公交从北城赶往南城,最后发现是因为你的设备没有接电脑……先不说维修人员对你恼羞成怒,最后你也留下了工作失职,专业性有待提高的笑柄给同事,真是两败俱伤、得不偿失啊。 而对于家庭用户来说,在处理打印机方面的常识就更薄弱了。其实很多时候你的设备并没有问题,而是你的操作方法有误,为了避免这种“悲剧”现象,笔者为大家搜罗整理一些这方面的解决方案,希望能为你的日常打印带来可行性的帮助。 喷墨打印机 驱动安装无法正常打印 原因之一:驱动程序属性中端口设置与实际使用端口不一致。 原因之二:USB连线引起的通讯问题,因为很多商家为了降低成本,赠送的USB连线都是三无产品,可更换一根质量好的。 出现断断续续的白线或字迹不清 原因之一:墨盒中已经没有墨水。由于一些比较老的喷墨打印机没有单一墨盒墨水用尽提示,造成浪费纸张及蓝非其它墨水的现象发生。可根据打印机内的提示自行更换墨水。在墨盒内墨水快用完时,字体颜色会明显变浅,并伴有打印的图像偏色想象发生,用户时刻关注下就可以避免此类事情的发生。 原因之二:墨盒中墨水有气泡。这种情况常见于灌装墨水的墨盒中,由于喷头被气泡堵住,无法及时释放墨滴,造成打印出白线的现象。可将墨盒取出喷头朝下左右晃动少许时间即可较好解决这种现象,如晃动无法赶走气泡,则需打印多张文档后,等气泡排除即可。 原因之三:喷头部分被堵住。通过打印机驱动中的清洗喷头选项,对喷头进行清洗。如果清洗后,自检图案的缺线会减少,证明清洗有效,应坚持清洗。如果清洗三次后还是打印出白线,可使用超声波加湿器在水中对喷头进行高频冲击,或将喷头浸泡在热手巾上一小时,即可疏通打印喷头。 打印喷头堵塞 原因之一:打印机内必须保持安装有充足墨水之墨盒,长时间不使用打印机极易造成打印头堵塞,所以必须保证一周内至少使用一次,否则打印头有可能会因墨水干枯而堵塞。由于墨水固化导致喷头堵塞,可使用一两次打印机驱动自带的喷头清洗功能,如果还是无法冲开喷头,用户可使用超声波加湿器在
