Appendix C. Maintenance and Adjustment
Thermal Printhead Cleaning
CAUTION!
The Printhead is the Most Fragile part of your Printer. Do NOT use sharp or
hard objects to clean the Printhead. Do NOT touch the glass surface of the
Printhead with your hand.
CAUTION!
During the print process the Printhead will become hot. Do NOT attempt to
clean the Printhead until it has had time to cool.
NOTICE!
To help keep the Printhead clean, the Top Cover of the Printer should be
closed when printing. To ensure print quality and prolong Printhead life, do
NOT use dusty or dirty print media in the Printer.
NOTICE!
Recommended cleaning intervals for the Thermal Printhead:
Direct Thermal Printing – Each time the label roll is changed.
Thermal Transfer Printing – Each time the ribbon is changed.
Printing labels will cause dirt such as paper dust,
particles of ink and label adhesive to accumulate on
the Thermal Printhead. This can cause poor print
quality and incomplete printouts. When this happens
the Printhead must be cleaned:
1. Turn the Printer Off.
2. Open the Top Cover.
3. Pull the Printhead Lever out and rotate it
upward to the right (counterclockwise) to open
the Thermal Printhead.
4. Remove the label stock and ribbon from the
Printer.
5. Clean the Printhead surface (see arrow) with a
special cleaning pen or a cotton swab soaked
in Isopropyl Alcohol.
6. Allow the Printhead to dry for 2-3 minutes
before turning the Printer back on.
