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 your MFC
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 for service.
Caution
Do NOT touch the print head. Touching the print head may cause
permanent damage and may void the print head’s warranty.
When an print head nozzle
is clogged the printed
sample looks like this.
After the print head nozzle is
cleaned, the horizontal lines
are gone.
