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.
