打印头是打印机的关键部位,同时它也是最易损坏的部件。由于打印头结构精密,一般用户维修打印头时困难较多。现根据个人维修经验,对STAR AR-3240常见故障的维修方法做一个介绍,仅供参考。一、AR-3240打印头的结构及工作原理 STAR AR-3240打印机打印头的基本部件主要有永久磁铁芯,打印头线圈,打印针,导针板等几部件,打印头的24根针都用螺钉固定于前护套上。永久磁铁、磁芯、打印头线圈组成一体合称打印头底座,底座上附有散热片,用于降低打印头工作时的温度。散热片用胶粘在底座上称为后盖,并用三颗小螺钉固定。打印头
The printhead is a key part of the printer and it is also the most vulnerable part. Due to the precise structure of the print head, it is more difficult for the general user to repair the print head. Is based on personal maintenance experience, STAR AR-3240 common fault repair methods to do an introduction, for reference purposes only. First, AR-3240 print head structure and working principle STAR AR-3240 printer print head basic components are permanent magnet core, print head coil, print pin, guide plate and other parts, the print head 24 pins are used Screw fixed on the front jacket. Permanent magnet, core, print head coil form a unified printhead base, base with heat sink, used to reduce the print head temperature. Heat sink with glue on the base is called the back cover, and with three small screws. Print Head
