2, slow data transmission speed: data transmission takes time, according to the path of data transmission (computer output port, data line itself transmission speed, printer receiving data port).
3. The belt aging of the printing equipment, the friction force of the driving gear connected to the motor will change to accelerate the aging of the printer's belt, and then cleaning and lubricating can reduce the failure of the belt aging.
4, it is necessary to pay attention to the wiring of the supply, do not cause the pulling situation to cause the car to move blocked. Because the internal structure of different printers is somewhat different, and it does not provide support for modification and supply, the wiring problem is the most encountered problem in modification and supply.
