I have lexmark x7170 all in one printer and i can't receive faxes it says memory full but when i try clearing it it says no pending faxes so i cam't. What can i do?

This temporary storage of fax may happen when one of your cartridge is detected low ink level. Try to replace your low ink cartridge. Sadly, if you have navigated away from the fax menu after inserting a new cartridge or clearing the message, you may lose the fax. You can try to have the sender resend the message. When this problem happens again, just replace your cartridge without turning off your printer. Once inserted, accept the incoming fax message to print it.
