TH—3070打印机虽然在电脑用户中仍占一定比例,但已日渐淘汰,市场上介绍此类打印机维修的资料很少。3070打印机性能比较稳定,一般常见的故障是出在归位不灵和打印缺针等等。 一、在打印过程中出现打印头不能归回左边正常位置。出现这种故障一般都是由于打印机使用时间较长;在某些传动环节上积存污物,使打印头在运动时磨擦力增大所致。出现磨擦力增大的原因有这么几种:一是色带盒内色带夹死或环绕过紧导致出带不顺畅,这时应该取下色带盒检查,检查色带是否夹死或者环绕过紧,如果夹死,可重
Although TH-3070 printers still account for a certain percentage of computer users, they have been phased out and there is very little information on the market to introduce such printer repair. 3070 printer performance is relatively stable, the most common failures are homing and printing missing needle and so on. First, the print head can not return to the left normal position during printing. Occurrence of such failures are generally due to the printer for a long time; accumulated in some of the transmission link dirt, so that print head friction caused by increased movement. There are several reasons for the increase of friction: First, the ribbon inside the cartridge clip or around too tight led to the belt is not smooth, then you should remove the ribbon cartridge inspection, check the ribbon is clipped or wrapped around Too tight, if caught, heavy
