Pitney Bowes J693 manual Cleaning the Printhead

5.5.1Cleaning the Printhead

When print quality begins to decline (indicated by symptoms including non-

cmpliant bar codes, print dropouts, and streaking), the typical cause is debris build-up on 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 nthe printhead. To clean the printhead:

oTurn ‘Off’ and unplug the printer.

Open the access cover. Unlock the Printhead Latch and raise the Printhead pAssembly. Move media and ribbon away as necessary.

Gently wipe away all surface build-up on the Printhead (see below) using a cotton swab moistened, not soaked, with isopropyl alcohol. Allow the

qprinthead to dry.

Re-install ribbon and media, if removed. Lower and rotate the Printhead rLatch to the locked position.

Close the cover. Plug in and turn ‘On’ the printer. Feed several labels to normalize tracking.

NEVER use a sharp object to clean the Printhead.
