Brady 6441, 3481, 2461 manual Cleaning the Printhead

5.3.1Cleaning 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:

ŒTurn ‘Off’ and unplug the printer.

•Open the access cover. Unlock the Printhead Latch and raise the Printhead Assembly. Move media and ribbon away from the printhead as necessary.

ŽUsing 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.
