5.1 Cleaning the Printhead
If print quality declines (symptoms include non-compliant bar codes, print dropouts, streaks), 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:
1. Turn ‘Off’ and unplug the printer.
2. Open the cover. Unlock the Printhead Latch and raise the Printhead Assembly. Allow the printhead to cool before
proceeding.
3. Move media and ribbon away from the printhead as necessary.
4. 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.
5. Replace the ribbon and media. Lower the Printhead Assembly back to the locked position.
6. Close the cover. Plug in and turn ‘On’ the printer. Feed several labels to normalize tracking.
