Avery Dennison Monarch 9860 Operator Handbook - Manual (Page 26)

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/linerless 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, use the enclosed printhead
CLEAN-STRIP.
1. Turn off the printer and open the cover and printhead
assembly.
2. Remove the label roll and ribbon (when cleaning the
printhead).
3. Press down on the exit cover tabs to open the exit cover on
the front of the printer.
4. Clean the platen roller when you see significant adhesive
build-up or a label is wrapped around the platen roller. Use a
dry, soft-bristle brush, such as a toothbrush, to clean either
the standard (black) or linerless (red/orange textured) platen
roller.
