Maintaining your printer Replacing cartridges CAUTION Using genuine HP supplies To ensure best performance, Hewlett-Packard Company recommends using only genuine HP supplies in HP inkjet printers. Refilling an HP print cartridge pushes the electronic and mechanical components of the cartridge past its normal life cycle, creating many potential problems, such as: Poor print quality. Non-HP ink can contain components that: 1) cause nozzles to become clogged, resulting in streaked copy and graying for fuzzy characters, and 2) corrode the print cartridge electrical components, resulting in poor printouts. Potential damage. If ink from a refilled cartridge leaks, the excess ink may cause damage to the service station that caps the cartridge while not in use. Because this service station maintains the health of the cartridge, quality problems may occur with the print cartridge. If ink from a refilled cartridge leaks onto the electrical components in your printer, severe printer damage can occur, causing downtime and repair costs. Damage resulting from the modification of or refilling of HP cartridges is specifically excluded from the coverage of HP printer warranties. MAINTENANCE 7 7-3
