Maintenance
Cleaning the BJ Cartridge Print Head
If your printouts become faint or streaked, or if their quality otherwise
deteriorates, clean the print head. To maintain the best possible print
quality, you need to clean the BJ cartridge print head from time to time.
c
Cleaning the print head consumes a small amount of ink. Cleaning
too often reduces the amount of ink in the BJ cartridge.
n
If your printing is faint, you can often correct the problem by adjusting
the print contrast and printing speed.
