152Troubleshooting - Printout is Unsatisfactory
Colours streaked or wrong
Check 1
Is the ink of BJ Cartridge on good condition?
If text or images are streaked, scratched, faint, or if the wrong colours are
printing, one of the ink tanks may have run out of ink, the print nozzles may
be clogged, or the print heads may be worn out.
Print a nozzle check pattern and check the printed patterns.

Check 2
Have the protective tape or cap been reattached?
After removed, the orange protective cap and tape should never be re-
attached to the BJ Cartridge. Re-attaching the tape or cap can cause air
bubble or trap dirt or dust into the ink and clog the ink nozzles.
If the protective tape or cap has been re-attached, remove it. Install the BJ
Cartridge in the printer and clean the print head immediately.
After cleaning the print head, if printing is patchy or streaked replace the BJ
Cartridge.
Check 3
Did you print on the correct print side of the media?
The correct print side is different for each type of media. Make sure that
the correct print side is facing up when you load the media in the auto sheet
feeder.
