Cleaning - Monarch 9855 Operator's Handbook Manual

C l e a n i n g
The rate and frequency at which you print determines how often you must clean the printer.
Note: You must clean the printhead as described below to maintain printhead life.
You may need to clean the printhead, sensor, and platen roller:

if there is any adhesive build-up in the supply path.

after printing approximately 3 rolls of thermal transfer/thermal direct/
supplies or after each ribbon.

daily if your printer is in an excessively dirty, hot, or humid
environment.

when you see voids or streaking in the print as shown.
When you are using higher speeds (with 203 or 300 dpi), and/or
increased print contrast, we recommend cleaning the printhead after
each ribbon with isopropyl alcohol. If you still notice build-up on the
printhead or black streaks on your supply, order a printhead
CLEAN-STRIP.
Turn off the printer and open the cover and printhead assembly.
