Cleaning Swab Kit for Printheads (Box of 25). The cleaning swabs can be used when print anomalies appear on cards to remove visible deposits from the print head. It is important to never use a sharp object to scrape depositsfrom the printhead, as it may permanently damage it. 

Zebra recommends cleaning the card printer every 1,000 cards and replacing the cleaning roller of the cleaning cartridge every 1,000 cards if used daily. If printer is used periodically, replace cleaning roller at least every four months.
