Care and maintenance

This chapter contains information about changing print cartridges, maintaining your HP
Fax, the menu settings, error messages, and troubleshooting.

Print cartridge information

The print cartridge life is very sensitive to the content of received faxes or copies you
make. To increase its life, we recommend you follow the instructions below:
• Always use the HP 701 (CC635A) black inkjet print cartridge.
NOTE: Your HP Fax was shipped with a starter ink cartridge. Replace the starter
cartridge when it runs out of ink with the HP 701 cartridge.
• DO NOT unpack the cartridge until you are ready to use it.
• Store it in the same environment as the fax machine.
• If you have unpacked the cartridge but are not using it, store it in an airtight plastic
bag.
• DO NOT leave it exposed for an extended period.
• DO NOT refill the cartridge. The warranty will not cover damage caused by using
refilled cartridges.

View ink level

When using the 17ml print cartridge, your machine allows you to check the amount of
ink remaining. To view the current ink level:
1. Press Menu repeatedly until TOOLS appears and press OK.
2. Scroll to View Ink Level by pressing
The machine displays a fractional number. For examples, 1/8 means that ink is low
and you need to replace the cartridge. 8/8 means that a new cartridge is installed.
NOTE: If the HP Fax is low on ink (ink level is 1/8), new faxes that come in will not be
printed. They will be stored in memory. You must manually print the faxes from memory
(see Reprinting faxes on page 40) until you replace the ink cartridge (see Replace the
print cartridge on page 44).
TIP: If memory become full before the print cartridge is replaced, the HP Fax will stop
answering the phone. Be sure to print the faxes out of memory regularly if you do not
immediately replace the ink cartridge.
