After the printer is used for a long time, the paper may not feed smoothly. How to solve this problem?
1. The stepper motor is faulty. The entire paper feeding process of the eco solvent printer is driven by the stepping motor. When the stepping motor fails, such as the main board damage, the sensor failure, etc., the eco solvent printer will have the problem of stepping and not feeding the paper. At this time, the motor needs to be inspected, maintained or replaced.
2. The paper feeding system of the eco solvent printer is abnormal. Under normal circumstances, when there is debris on the paper feeding platform of the eco solvent printer that blocks the paper, the eco solvent printer will not feed the paper; in addition, when the paper feeder of the eco solvent printer fails and does not work, it will also cause the eco solvent printer to feed abnormally. At this time, it is necessary to check the lower paper feeding system, clean up abnormal links and replace faulty parts. 
3. The pinch roller problem. There is a component in the eco solvent printer called the “pressing wheel”, which is used to ensure that the eco solvent printer is flat and not skewed. However, when the pressing wheel does not rotate, the pressing is too tight or too loose, it will also cause the printer to not feed the paper smoothly, or even cause the paper to not feed. At this time, test to see if there is any problem with the pressure roller, and adjust or replace it in time.
4. Paper pressing problem. When the press sheet of the eco solvent printer is too tight, it will cause the eco solvent printer to not feed smoothly, or even the paper will not feed. At this time, you need to loosen the paper pressure to ensure smooth paper feeding.
