chapter 6

Do not open the print carriage access door of the HP Fax unless necessary. This uncaps the nozzles and exposes them to air. The print cartridges have microscopic nozzles that can clog when exposed to the air for more than a few minutes. The HP Fax is designed to prevent nozzles from drying out under normal use.

•Turn off the HP Fax from the front panel and not from a power strip.

•Clean the print cartridges when you notice a significant decrease in print quality or when the print cartridges have not been used for a long time.

Caution! Do not clean the print cartridges unnecessarily. This wastes ink and shortens the life of the cartridges.
