  在修理标签打印机恒发彩票平台时,不关电源就插拔板子或芯片,这是非常风险的。由于在插拔板子和芯片时,不可能将其很平整地脱离插座,稍有倾斜,就可能将直流电源触及其它引脚,很简单形成损坏.3.不正确的交流电源接线。交流电源接线问题,简单被人忽视。一般总认为只要插座上有电就能运用,其实不然。微机的接地处理比较简单,一般机壳既是保护地又是直流地。主机和打印机衔接后,信号电缆线中的接地线把主机和打印机衔接成等电位。有时主机选用三眼插座供电,而打印机却选用二眼插座供电,再加上交流电源选用不同的接线方法,形成一头机壳接地,而另一头机壳却带电。在这种情况下,即使关闭电源,插拔信号电缆线也感觉到麻手,这简单引起主机和打印机接口损坏。
