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  and press OK.
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.
