then check it.

Press Stop/Exit.
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.
