1. There is still air in the printhead, try a few times more.

2. Tube interface is bad, need to insert or replace the interface.

3. There is leakage of printhead, need to find out where the gas leak and then use glue sealing.

1. The servo motor is broken, we need to replace the servo motor.

2. The encoder sensor is dirty, need to use cotton swabs dipped in water to clean.

3. The encoder sensor is broken, we need to change a new one.

The appearance of printing paper bulging can severely affect the printing effect, even cause print pictures of scrap. There are many reasons causing the feeding of the arch as following:

A. Check to see if it’s the reason of the material itself, material is unqualified or inferior materials; Materials not only can cause unusual paper feeding , also can cause printed images halo ink, and so on and so forth. Other materials can also cause paper feed bulging of be affected with damp be affected with damp, and so on and so forth, so pay attention to the materials are properly placed at ordinary times, completes the moistureproof work.

B. The direct reason is the abnormalities of feeding system. For example,the step of upper paper is not in accordance with roll paper. Another reason is that there is onstacle picture drawing end leading to the feeding bulging. It’s time to remove obstacles and adjust the scraps of paper press while to see if pressure paper too tight, causing the paper feed poorly.

C. Another reason is that the drying fan is abnormal.The principle of drying fan is the fan rotation causing the pressure upon the material greater than the pressure under the material, so that the material can be firmly attached on the front panel. The abnormal of function of the drying fan can cause abnormal paper feeding.

Wiper is mainly used to scrape excess ink from the printhead, prevent fly ink appeared in the printing process; motor drives the paper feeding and the carriage to complete the process of printing.

Wiper plays the role of cleaning the printhead and is installed under the printhead, on the left of the capping station. If there is something wrong with wiper, ink off will appear in the printing process.

Motor, the core motivation of printer, includes step motor and servo motor, the step motor controls the back and forth of paper; Servo motor controls movement back and forth of carriage, the power is also supplied by motor.The quality of motor, also directly affects the operation of printer, such as printer bracket flow, resistance and so on these failures are caused by broken motor.

Piezo printers adopt micro piezoelectric inkjet technology. The whole ink system is closely connected in order to ensure the sealing among cartridges, refill tube, printhead and damper. If there is a bad seal, many problems will appear, for example, printer is ink off, the printer can’t supply the ink, the printer can’t pump ink as normal, the ink comes back to damper etc. Printer can’t pump ink is a common bug, here are some reasons:

A. The position of the capping station is not good, you can try to debug the position of the capping station.

B. The deformation or aging of the capping station core, we recommend replace capping station core (pls pay attention to the maintenance and cleaning of the capping station core).

C. The ink pump does not work well, check the line to see if there is something wrong with the connection.

D. There is something wrong with the cable connection of printhead.

E. Printhead is damaged, we suggest replace a new one.

F. There is something wrong with the adjustment of the carriage frame and it’s possible that the position of the capping station is wrong.
