A thermal printer card is the quickest and easiest way to clean the Print Head, Drive Roller
and Peel Edge all at the same time. Follow the steps below for the proper cleaning
procedure:
1. Remove any installed media.
2. Dampen both sides, of one end, of the cleaning card with isopropyl alcohol.
3. While pushing down on the Head Lift Lever, insert the card into the front of the printer
between the Print Head and the Peel Edge (Figure 10-1).
4. Continue inserting the card until you feel resistance, now release the Head Lift Lever.
5. Using both hands, slowly pull the card out of the printer (See Figure 10-2).
6. Repeat as necessary.
7. Reinstall media.
Thermal cleaning cards should not be used more than three times each, and extremely dirty
cards should be disposed of immediately.
