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 (see p. 9-5). If the pattern is broken or missing,
clean the BJ cartridge print head.
Replacing the BJ cartridge ___________________
Note
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.

The fax cleans the print head.
Note
You can clean the print head up to five consecutive times if necessary.
After cleaning, print the nozzle check pattern to check if cleaning corrected the problem
(see p. 9-5).
If cleaning does not improve print quality, replace the BJ cartridge (see below).
Note
Do not replace the BJ cartridge while the fax is printing or performing another operation.
If you need to unplug the fax, wait until it returns to standby mode (time and receive mode displayed on
the LCD). Otherwise the cartridge holder may not be in its home position, causing the BJ cartridge to
remain uncapped and dry out.
1
Make sure the fax is plugged in.
2
Open the printer cover.
Caution
Do not try to manually move or stop
the cartridge holder.
Do not touch the components shown or
any metal parts.
