First of all, we need to know what is the raster strip of digital printer? The raster strip is a transparent film on which the dots are evenly distributed, and it acts as the ruler of a digital printer. The printing pattern of digital printing machine needs to be positioned by means of the raster strip. If the raster bar is dirty or dusty, the calculation will be inaccurate and the printing effect can be bad. Then how should we do if the raster strip of digital printer is dirty? 

  The raster strip sensor can sense the scale so as to define the correct print range. If the raster strip of the digital printer is dirty, there will be inaccurate counting, and the printed pattern will turn to the direction towards left and right or up and down. Therefore, if there is any stain or dust accumulation on the surface of the raster, the sensor will not be able to perceive the scale on it and cannot define the movement range of the carriage. 

When these mentioned problems appear, the possible reason is that the raster ruler of digital printer is dirty so you must clean it in time. You can use absorbent cotton or a clean cloth dipped in alcohol to wipe the raster ruler of digital printer from beginning to end. Remember to wipe it in one direction. Don’t wipe it back and forth so that you can ensure the clean state of its surface. 

  After cleaning the raster ruler, you can clean the raster plate. The position of the grating plate is easy to find. As long as you remove the two screws on the dust cover, you can see the raster plate and the sensor of the raster. For cleaning the valuable parts inside the digital printing machine, it is best to clean with alcohol, because alcohol evaporates quickly and will not stay too long. 

  In addition, it should be noted that when cleaning the raster strip, there is no need to clean it with any other liquid. After cleaning the component, blow away the large particles of dust first, and then wipe it with a dust-free cloth or cotton swab. If it is not clean, then use tissues dipping in alcohol and wipe it in the same direction. And pay attention to the cleaning process, you should not scratch the raster strip or make it wet, otherwise in the next printing it can have a double shadow. 

  How to do if the raster strip of printer is dirty? We need to clean it in time. If the raster is damaged, we need to replace it in time to avoid inaccurate printing effect and waste of resources In addition, if you want to print a better pattern effect, you can choose Ningbo Haishu Colorido Digital Technology Co., Ltd.
