These  Pre-saturated, disposable ID Card Printer Cleaning Cards are  designed to safely and effectively remove all types of dirt, magnetic oxide  and other contaminants that build up in your printer.  The regular use of these Cleaning Cards will clean and maintain important parts of your printer: including the Print Head, Transport Rollers, and Magnetic Encoder Station

Cleaning your 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
