Mask Spring Cleaning

Look at the mask spring behind the print head. If the mask spring needs to
be cleaned, go on to the next page. If the mask spring appears to be in
good condition, install a new ribbon cartridge as described on page 13.

Do the following to clean the mask spring:
1 Unlatch the print head locking tabs to release the print head, lift the
print head and set aside, then lift up the paper bail. Do not detach the
print head unit.
Never use a sharp object, such as pinchers, to clean between the
print head and the platen (rubber roller). This can damage the mask
spring and print head.
2 Remove the clear plastic paper guide that seats the mask spring, if neces-
sary. Use your fingernails to loosen the base of the paper guide, then
pull the paper guide straight up from the printer mechanism.
3 Remove the metal mask spring from the paper guide and clean with a
quality cleaner. Replace if damaged.
4 Put the good, clean mask spring into the paper guide and install the pa-
per guide into the printer.
