If you still see missing ink in this Print Quality Check Sheet, repeat the cleaning and
test print procedures at least five times. If ink is still missing after the fifth cleaning
and test print, replace the ink cartridge for the clogged colour. (Perhaps the ink
cartridge was in the machine over six months or the expiration date written on the
cartridge package has passed. Or, the ink may not have been stored properly before
use.)
After replacing the ink cartridge, check it by printing another Print Quality Check
Sheet. If the problem still exists, repeat the cleaning and test print procedures at
least five times for the new ink cartridge. If ink is still missing, call your Brother
dealer or Brother for Service.
Do NOT touch the print heads as this may cause damage to the print heads
or product. Such damages will not be covered by warranty.
