To clean the print head
1. If print quality deteriorates as described above, first clean the print head. Press
and hold down the RESUME button until you hear two beeps then release it.
Cleaning requires about 30 seconds.
2. After cleaning is completed, print the Nozzle Check Pattern to see if the print
quality has been restored. (p45) If horizontal lines are missing on the Nozzle
Check Pattern, the print head may be still clogged.
3. Clean the print head unit once again.
z If a printed page or the Nozzle Check Pattern is almost blank after one or
two cleanings, the ink cartridge has run out so replace it with a new one.
(p66)
z If print quality is not restored after replacing the ink cartridge, start
flushing.
To start flushing
1. Press and hold down the RESUME button for about six seconds until you hear
three beeps. Flushing requires about 60 seconds.
2. After executing flushing once or twice, print a page or the Nozzle Check
Pattern. (p45) If you see irregular dots or lines on the printed page, this means
the print head has worn out.
3. Replace the BJ Cartridge with a new one. (p72)
