4.4.2 Platen Roller Cleaning
Print quality can decline if the platen roller becomes contaminated with
paper dust, grit or adhesive. When this build-up is not removed, it can
cause abrasive damage to the printhead. Clean the Platen Roller as
follows:
 Turn ‘Off’ and unplug the printer. (ST Models: Raise the access
cover; see Section 3.2.)
 Slide the printhead latch to the ‘unlocked’ position and then raise (or,
in the case of SV Models, lower) the printhead assembly; see Section
4.4.1. Remove any ticket stock.
 Using a cotton swab or lint-free cloth dampened with isopropyl
alcohol, remove all debris on the Platen Roller. Manually rotate the
roller and repeat until the entire surface has been cleaned.
CAUTION
NEVER use a sharp object to clean the Platen Roller. Damage
can result.
