clean the
printhead
contacts
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

Release the gray print carriage latch and then lift the print carriage to
access the printheads.
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.
