HP 4000 K210 manual To clean the print cartridge contacts

Make sure you have the following materials available:

•Dry foam rubber swabs, lint-free cloth, or any soft material that will not come apart or leave fibers.

TIP: Coffee filters are lint-free and work well for cleaning print cartridges.

•Distilled, filtered, or bottled water (tap water might contain contaminants that can damage the print cartridges).

CAUTION: Do not use platen cleaners or alcohol to clean the print cartridge contacts. These can damage the print cartridge or the product.

To clean the print cartridge contacts

1.Turn on the product and open the print cartridge door. The print carriage moves to the center of the product.

2.Wait until the print carriage is idle and silent, and then unplug the power cord from the back of the product.

3.Lightly press down on the print cartridge to release it, and then pull it towards you out of the slot.

NOTE: Do not remove both print cartridges at the same time. Remove and clean each print cartridge one at a time. Do not leave a print cartridge outside the HP Printer for more than 30 minutes.

4.Inspect the print cartridge contacts for ink and debris buildup.

5.Dip a clean foam rubber swab or lint-free cloth into distilled water, and squeeze any excess water from it.

6.Hold the print cartridge by its sides.
