1. There is something wrong with the printer itself, and the printing speed is slow; 2. The data transmission speed is slow; 3. The belt of printing equipment is aging; 4. There is a problem with the continuous supply of wiring, which causes the movement of the carriage to be blocked; 5. After long-term use, the friction between the drag plate and the connecting rod in the machine becomes larger, and the increase of resistance leads to the slow operation of the motor.

1. Problems with the machine itself: Many machines can adjust the printing speed, just adjust it directly on the machine.

2. Slow data transmission: data transmission takes time, which is related to the path of data transmission (computer output port, data line transmission speed, printer receiving data port).

3. The belt of the printing equipment is aging, and the friction of the transmission gear connected with the motor will increase, which will accelerate the belt aging of the printer. At this time, cleaning and lubrication can reduce the failure of belt aging.

4. Pay attention to the connection of continuous power supply, and don't block the movement of the front car because of pulling. Because the internal structure of different printers is somewhat different, and the support of refitting continuous supply is not provided, the wiring problem has become the most common problem encountered in refitting continuous supply.

5. Lubricate the connecting rod. Sometimes the printing speed is slow because it takes a long time. The friction between the carriage and the connecting rod in the machine becomes larger, and the increase of resistance leads to the slow operation of the motor. Lubricating the connecting rod can solve the problem at this time.

6. Replace the motor. When the rubber hose of the continuous ink supply system rubs against the printer wall, the load of the motor will increase, and the long-term use of the motor will cause loss.
