6.4 Print head Maintenance
If print quality has not improved after cleaning using a thermal cleaning card or if one is not
available, foam or cotton tipped swabs dampened in isopropyl alcohol may be used. Refer
to Figure 18 and follow the steps below for the proper cleaning procedure.
1. Remove any installed media.
2. Turn the power to the printer OFF.
3. Using the two Head Release Levers (Figure 15), unlatch and raise the print head.
4. With a foam or cotton tipped swab dampened in isopropyl alcohol, clean the thermal
elements by gently rubbing the swab down the length of the print head. Allow for the
alcohol to evaporate then repeat if necessary.
5. The Drive Roller, Peel Edge, and other basic internal cleaning may also be
performed at this time. See the appropriate sections for more information.
6. Latch the print head completely and reinstall the media.
7. Turn the power to the printer ON.

always make sure that the print head is latched completely before
installing the top cover. Failure to do so may result in damage to
the print head.
