Cleaning the Ink Cartridge & Maintenance Station
It may be necessary to clean the ink cartridge nozzles if you notice reduced print quality, or if you
suspect a cartridge nozzle has become slightly dried out or clogged. If you are having print quality
problems, follow the steps below:
1. Remove ink cartridge from printer.
2. Fold two paper towels four times each and soak in a glass of water for five seconds.
Note:
Do not squeeze excess water from paper towels.
3. Place one paper towel on cartridge nozzles and gently press for 30-40 seconds.
4. Unfold the second paper towel, place on a flat/hard surface and press the cartridge, nozzle
side down, on to the top edge of the paper towel.
5. Firmly tap the top of the cartridge three times to force the ink out.
6. Drag the cartridge down the paper towel towards you,
repeating until all three colors are on the paper towel.
If all three colors are not showing up on the paper towel,
repeat steps 5 and 6. If the paper towel still doesn’t show all
three colors replace the cartridge.
7. Clean the copper contacts with a paper towel dampened
with rubbing alcohol.
8. Thoroughly dry the entire cartridge with a clean paper towel.
IMPORTANT!
Printer damage may result if cartridge contacts
are not completely dry.
