Cleaning The Printhead - Datamax I-4206 Operator's Manual

5.3.1

Cleaning the Printhead

If print quality declines (symptoms include non-compliant bar codes, print
dropouts, streaks; see Section 4.3.4), the typical cause is debris build-up on the
printhead. Furthermore, when the build-up is not removed it may lead to element
failure, greatly reducing the life of the printhead. To clean the printhead:
Turn 'Off' and unplug the printer.
Open the access cover. Unlock the Printhead Latch and raise the Printhead
Assembly. Allow the printhead to cool before proceeding.
Move media and ribbon away from the printhead as necessary.
Using a cotton swab moistened, not soaked, with isopropyl alcohol gently
wipe away any build-up on the Printhead surface, paying close attention to
the Burn Line. Allow the printhead to dry.
Replace the ribbon and media. Lower the Printhead Assembly and rotate the
Printhead Latch completely back, 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.
