Working principle and maintenance method of print head

① The principle of inkjet pen and the resolution of inkjet printing.

The spray hole of the fountain pen consists of two rows, 150 in each row, a total of 300. The two rows of spray holes are distributed in a cross shape. The maximum spray printing coverage area of each fountain pen is 0.5 inch. By adjusting the resolution of the printing software, the printing frequency can be controlled. 600 * 600dpi refers to printing 600 points within 1 inch, 600 * 300dpi refers to printing 300 points within 1 inch, and 600 * 200dpi refers to printing 200 points within 1 inch.

② Use and maintenance of heads

The nozzle must be cleaned and emptied after shutdown within two days. The cleaning and emptying steps are as follows:

1: Adjust the nozzle valve to the cleaning position (vertical to the platform and upward position);

 2：Clean the surface of the cleaning solution pipe at the back of the chassis (prevent the dust on the surface from entering the nozzle) and insert it into the cleaning solution bottle (pay attention to seal the cleaning solution after use, and keep the cleaning solution pipe clean);

3:Lift the bottom of the nozzle and put it into the tray. Press the cleaning button to clean the nozzle. During the cleaning process, release the cleaning button every 3-4 seconds (to prevent the nozzle from being damaged by excessive pressure), and do so repeatedly until the nozzle is cleaned;

4：After the nozzle is cleaned, empty it (to prevent the cleaning liquid from returning to the cartridge when the machine is used to squeeze ink next time). Press the evacuation switch button (the blue light is on after pressing), and press the cleaning button when the blue light is on. This is the evacuation operation. During the evacuation process (the blue light is on), release the cleaning button every 3-4 seconds, and do so repeatedly until the cleaning liquid is discharged by the nozzle;

5:Cover the nozzle with nozzle shield to prevent light and dust.
