We need to know the reasons for the ghosting of digital printing machines, which are usually caused by Encoder Strip, carriage, parameter calibration and so on. Then we have to check these reasons step by step, and we can solve the problem of digital printing machine ghosting quickly.
The Encoder Strip plays the role of positioning, and the Encoder Strip Sensor is installed on the small carriage, which can help the digital printing machine to accurately position the drawing position and realize the high restoration of the picture. Once the Encoder Strip is dirty or damaged, it will result in inaccurate reading of the Encoder Strip Sensor, deviation of printing, ghosting or misalignment, etc. In this case, it is necessary to clean the Encoder Strip or replace the new one.
The small carriage is equipped with a Encoder Strip Sensor. Once the small carriage is not running smoothly, or the small carriage is stuck, the nozzle will be inkjet, which will cause the digital printing machine to have a ghost image. The small carriage does not run smoothly, mostly because the guide rail is too dirty or the car washer and the slider are worn. In this case, it is necessary to clean the guide rail or replace the worn parts.
The calibration of the parameters of the digital printing machine is inaccurate, which may also cause the ghosting of digital printing. Inaccurate vertical alignment can cause vertical ghosting; horizontal calibration is inaccurate and lateral ghosting occurs, In this case, you need to open the print settings in the software, then find the two-way calibration, and adjust the parameters to test.
