9-8 Maintaining the MultiPASS C3500 Chapter 9
Cleaning the BJ Cartridge Print Head
To maintain the best possible print quality, you need to clean the
BJ cartridge print head from time to time. Your MultiPASS is
equipped with a print head cleaning function. If you notice some
degradation in the print quality, try cleaning the print head.

Cleaning the print head consumes a small amount of ink. Cleaning too
often reduces the amount of ink in the BJ cartridge.
❍ Make sure the MultiPASS is plugged in.
The unit cleans the print head.
❍ When cleaning ends, the MultiPASS beeps once to let you
know it is done, and returns to Standby mode.
❍ Do this five consecutive times if necessary.
❍ If the problem persists, install a new BJ cartridge.
