Some customers may find that after cleaning the printhead of the printer, the color of the printed image becomes lighter (when the pixels of the image, the printing speed, and the number of PASS are normal), this is very confusing. So what is the reason for this phenomenon? Here are some simple analyses.
Ink is a volatile liquid. When the cleaning time is long, the permeability of the output medium is strong, and the phenomenon that the printed image becomes light is prone to occur. Therefore, we should clean the print head as soon as possible before printing to avoid color difference. Then some users may ask whether it is not necessary to clean the printhead? The answer is no. If the printhead is not cleaned for a long time, the nozzle will be clogged, and the quality of the printed image will be reduced, and the printhead will be damaged. Therefore, the cleaning of the print head is one of the necessary tasks for printer maintenance. There is also a situation where the ink dries quickly. If you use original ink or ink specified by the manufacturer, this situation is rare. Here, it is recommended to use original ink or ink specified by the manufacturer.
