Cleaning the BJ Cartridge Print Head

If your printouts become faint or streaked, or if their quality otherwise deteriorates, print the
nozzle check pattern to see if the print head nozzles are operating properly (→ p. 12-10). If
the pattern is broken, missing, or a specific colour is not printed, clean the BJ cartridge print
head.
Refer to the flow chart (→ p. 12-9) for the correct order of testing and cleaning the BJ
cartridge print head.
n• To maintain the best possible print quality, clean the BJ cartridge print head from time to time.
• Cleaning the print head consumes a small amount of ink. Cleaning too often reduces the amount
of ink in the BJ cartridge or tanks.
• If your printing is faint, you can often correct the problem by adjusting the print settings.
