5.6.1
Cleaning the Printhead
If print quality begins to decline, indicated by symptoms including non-
compliant bar codes, print dropouts, streaking and smudging, the typical cause is
debris build-up on the surface of the printhead (see Section 4.3.4). Furthermore,
if this build-up is not removed it may lead to premature element failures, greatly
reducing the life of the printhead. To clean the printhead:
n
Turn 'Off' and unplug the printer.
o
Open the access cover. Unlock the Printhead Latch and raise the Printhead
Assembly. Move media and ribbon away as necessary.
p
Gently wipe away all surface build-up on the Printhead (see below) using a
cotton swab moistened, not soaked, with isopropyl alcohol. Allow the
printhead to dry.
q
Re-install ribbon and media, if removed. Lower and rotate the Printhead
Latch to the locked position.
r
Close the cover. Plug in and turn 'On' the printer. Feed several labels to
normalize tracking.
; ;
Note: NEVER use a sharp object to clean the Printhead.
