I had this problem as well - try the following:

1) Change your rings-to-answer from the default of "1" to "3". This is found in the basic fax setup on the control panel of the printer itself.

This solved the problem for receiving faxes that I was having when testing fax reception by the HP 2320nf from an dedicated fax. The remote fax would fail after repeated rings with a "BUSY" indication in the fax error report it printed. "BUSY" equals either actually "busy" or also it can mean "no answer".

What I found on the 2320nf end was that it had detected an inbound fax but never answered it. The color LCD on it had "fax received" but the device itself appeared hung.

Hope this helps.

Might need a new printer. Lexmark printers can be troublesome.

Verify no pieces of the card paper are missing and try printing on plain paper to make sure. Then try new card paper and make sure none of the perforations are separated.

sounds like the faxes are stuck in memory
look in the Troubleshooting section of the manual
