一、激光打印机维护保养完全手册激光打印机是现代办公不行缺少的办公设备，它的使用为宽阔的办公用户带来了很大便利，同时也大大提高了办公效率。
大家在使用激光打印机时，除了要知道简洁的操作步骤外，还要对打印机的维护、正确的使用及常见故障的解决有所了解，这样才会更好的利用激光打印机为日常办公工作效劳。
一、打印机常见部件的维护激光打印机自身吸附灰尘的力量很强，在打印工作时不行避开地会有一些粉尘残留在机内的一些部件上。
由于激光打印机热量会将这些粉尘粉尘变成坚硬的固体，从而影响到激光打印机的正常使用，甚至使激光打印机发生故障。
激光打印机需要维护的部件包括电极丝、激光扫描系统、定影器局部、分别爪及硒鼓等。
1、电板丝的维护电极丝沾污了废粉、纸灰等，会使打印出来的印件墨色不够、纸样反面脏污或输出的打印件底灰严峻。
维护电极丝时应留神地取出电极丝组件，有些型号的打印机不必取出电极丝，可直接在机子上进展清洁，可以先用毛刷刷掉其上附着的异物，然后再用脱脂棉花将其轻轻地认真擦拭干净。
2、扫描系统的维护激光扫描系统中的激光器及各种镜片被粉尘等污染后，会造成打印件底灰增加，图象不清。
可用脱脂棉将它们擦拭干净，如不行可用脱脂棉醮少许酒精擦拭干净，擦拭时肯定要留意不能转变它们的原有位置或碰坏。
3、定影辊的维护定影加热辊在长期使用后可能粘上一层墨粉等脏物，就会影响打印效果，如消灭黑块、黑条等。
与加热辊相配对的橡皮辊，长期使用后也会粘上废粉，一般较稍微时不会影响输出效果，但假设严峻时，会使输出的样稿反面变脏。
这时就需要清洁加热辊和橡皮辊，可用脱脂棉蘸无水酒精留神地将其擦拭干净。
但不行太用力擦拭加热辊，橡皮辊的擦拭可简洁一些，只需将其外表擦干净即可。
4、分别爪的维护分别爪是紧靠加热辊的小爪，主要作用是分别纸张，避开纸与热辊相粘而卡纸，其爪尖长期与加热辊和纸张摩擦，可能会粘上废粉结块，从而使纸张输出时变成弯曲褶皱状，甚至引起卡纸。
因此，如觉察输出纸张有褶皱时应留意清洁分别爪。
