Cleaning your P330i, P330m and P430i Zebra ID card printer is one of the easiest things that can be done to help maintain optimal printing functionality. Cards carry dust and other tiny debris with them through the printer's internal print path. Dust and debris can potentially degrade your image quality and damage your printhead or other critical parts of your card printer. With routine cleanings and replacement of cleaning rollers, you can expect optimal image quality and a longer life for your card printer.
