PRINTER MAINTENANCE AND
TROUBLESHOOTING
Cleaning
You may need to clean the print head and platen roller after printing a number
of rolls of paper, whenever you load new supplies or when you see voids in the
printout.
Caution
:
Do not use sharp objects to clean the print head. This may
damage the printer and require service.
1. Open the paper supply door by placing your fingers under the “T”
pull-handle and pulling up firmly.
2.
Remove the paper supply roll.
3. Moisten a cotton swab with isopropyl alcohol and clean the print
head.
4.
Clean the platen roller with a dry cloth or small brush. You can also
use another cotton swab moistened with isopropyl alcohol. Turn the
platen roller with your finger and run the cotton swab or dry cloth
across it. Make sure the platen roller is clean all the way around.
5. Moisten another cotton swab with isopropyl alcohol. Rub the swab
across the black mark sensor to remove any build-up.
6.
Moisten another cotton swab and rub the swab across the tear bar to
remove any build-up.
You may experience dust build-up depending on the environment and the
quality of the paper supply you use. If this occurs, use a can of compressed air
to blow dust and paper debris out of the printer.
