Print Head Cleaning
• Print head cleaning consumes ink. Do this procedure only if you see a problem in the Nozzle Check
test pattern.
1. Check the ink level indicator in the printer driver or the operation panel display to determine if the
print cartridge is empty.
2. Print a Nozzle Check test pattern.
3. Look at the Nozzle Check pattern to determine which nozzles are blocked.
• If one or more color is missing, is extremely faint, or shows broken lines, this tells you where there
is a blockage.
4. Pull the release under the operation panel forward and raise the scanner unit.
5. Confirm that the envelope selector is forward.
