Clean the printhead copper contacts only if you get repeated front panel
messages prompting you to check a printhead after you already have.
Caution! Do not remove all printheads at the same time.
Remove and clean them one at a time.
Make sure you have the following materials available:
• A clean, lint-free cloth
• Distilled, filtered, or bottled water (do not use tap water, as it may
contain contaminants that can damage the printheads).
Caution! Be careful not to get ink on your hands or clothing.
1
Turn the unit on and open the print-carriage access door.
The print carriage moves to the center.
2
After the print carriage has moved to the center, unplug the power
cord from the back of the unit.
Warning! It is very important that you disconnect the
printer from its electrical power source before touching
the printhead contacts. Electrical shock or severe
damage to the printer can occur if you touch the
contacts while there is electrical power to the printer. Do
not use the On button to turn the printer off.
3
Release the gray print carriage latch and then lift the print carriage to
access the printheads.
4
Remove the printhead by lifting the printhead handle and pulling
upward.
5
Inspect the copper contacts and the contacts inside the printhead
socket for ink and debris buildup.
6
Clean any visible ink deposits with the clean, soft, lint-free cloth.
If necessary, moisten the cloth with one drop of water.
Caution! Clean only the copper contacts in the front of the
printhead, and wipe upwards only. Do not clean the ink
nozzles on the under side of the printhead. They can become
damaged or clogged by this type of cleaning.
