Cleaning Ink Cartridge Electrical Contacts
If the printer is used in a dusty environment, a small amount of debris may accumulate on the ink
cartridge contacts. You can clean the contacts with distilled water and lint-free cotton swabs.
Caution: Do not use tap water to clean the ink cartridge electrical contacts. Tap water may contain
contaminants that can damage the ink cartridge.
Caution: Use care when working with ink cartridges. Ink cartridges can be damaged from
improper handling. See “Handling Ink Cartridges” on page 24.
