Cleaning the Ink Carrier Contacts

The ink carrier contacts are located inside the ink cartridge
carrier. To clean them it will be necessary to again remove
the ink cartridge.
1. Remove the ink cartridge (see pages 49-50).
2. Use a clean dry cloth to reach into the ink carrier and
wipe the contacts clean.
3. Re-install the ink cartridge (see pages 50-51).
4. Run a nozzle test (function 52) to re-check the print
quality.
If print quality is still poor, replace the ink cartridge. If
there is still no improvement, contact your dealer for
service.
