Cleaning the Thermal Printhead

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.
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. Release the Print Mechanism by pushing in
on the Head Latches. The Print Mechanism
will now rotate up.
4. Remove the ribbon from the Printer.
5. Clean the Printhead surface (see blue 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.
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
