[故障现象] M1724打印机装好纸后,开机初始化正常,字车归位后,指示灯power+check+sheet(纸尽)亮,操作打印机控制板,使其恢复到正常状态,但是,只要启动打印程序(即使用打印机进行打印),纸尽灯就会复亮,且主机显示no paper error writing device PRN,打印机不能正常工作。 [故障分析]打印机开机后初始化正常,说明打印电路工作基本正常。将打印机换接到另外一
[Symptom] After the M1724 printer is installed with paper, the power-on initialization is normal. After the car is homed, the power light + check + sheet is on and the printer control board is operated to return to the normal state. However, Print the program (that is, use the printer to print), the paper is lit the lamp will be bright, and the host shows no paper error writing device PRN, the printer does not work. [Failure Analysis] Initialize the printer after boot normal, indicating that print the basic work of the circuit. Change the printer to another one
