Cleaning the Ink Cartridge Contacts
If an ink cartridge is installed but not recognized by the printer, you can clean the electrical
connection points to resolve the issue.
Use the following instructions to clean the electrical contacts on the ink cartridges. The
electrical contacts in the ink cartridge slots inside the printer can also be cleaned.
Note: Wear protective gloves to prevent ink from staining your hands during this procedure.

Dampen a clean, lint-free cloth with deionized water.
Do not use paper towels, napkins, or any other material that may leave lint or debris behind
while cleaning. Problems can occur if lint enters the interior of the printer.
Hold the transport unit cutter frame [1] with one hand. With your other hand, use the cloth
to clean the four belts on the transport unit.

Note: If deionized water is insufficient, Goo Gone® may be used as an alternative.
If necessary, you can grasp and move the belts manually in either direction to expose more
belt surface area for cleaning. All four belts will move at the same time.
If the belts are damp from cleaning, allow them to dry completely before reinstalling the
transport unit.
Power off the printer.
On the rear of the printer, turn the power inlet switch off.
