Do you have Digital, DSL, Vonage, or a Cable phone Line?

Fax machines only work on ANALOG phone lines.

          Receiving faxes, won't send faxes. Comes up line

          Your fax machine thinks everything is OK. If you can receive you can send.

          call the failing fax number with a regular phone and listen for fax tones.

          We have a HP colour laser jet CM2320nf MFP and when we try and send a fax it comes up with error report Comm Error 345. Please explain

          Check phone line. use a normal phone and plug into the same phone wall socket that the MFP is using, do we have a dial tone? Do we have a noisy line, any buzz or crackel will cause issues

          If there is no dial tone ring line supplier, If it is noisy line do the same

          Also check phone line is plug into "line" socket in the back of machine not "ext'

          Also check no prefix is required to dial out, unit needs its own phone line..

          Also try using resolution of fax as standard not fine, this requires less info to go threw the line

          In Australia we have a thing called folds (fax online diag service), basicly it is a fax number you ring and the phone company who own the line send back a report, most times the issue is noisy line or no line available

          hope this helps

          Fax interrupts phone call

          1. Make sure your [RINGS TO ANSWER] settings are more than the same settings for your answering machine.
          2. If someone tries to make a copy while the phone line is in use, they need to press number 1, as if telling the unit that they want one copy. If not, the unit will think you are trying to receive a fax and will interrupt the communication.

          Be blessed.

          Fax machine stoped receiveing fax

          First, check your fax's phone line. Put a regular phone on it and check for dial tone and line noise. If the line is dead or noisy, this will cause a problem. 
          You can also try dialing your fax number from another phone and see if the fax unit picks up the line and starts initiating communication. (sounds like modem noises)

          My Lexmark X4270 will send out faxes but when someone sends me a fax it rings once and no face comes through. I have been trying to figure this out for weeks. Please help. I need it for my buisness and I...

          95 percent of the time that is a phone line issue.
          If there is more than one item on that line, it can be an issue.
          I will throw out everything since I am not there.
          A DSL or digital phone line can cause that problem. The majority of fax machines still require an analogue phone line.
          Make sure that Junk Fax is off, secure fax is off, and that the ECM mode is ON. ECM is error correction mode.
          Also be sure manual receive is not turned on.
          I strongly suspect a phone line issue. I will explaine.
          There are 3 phone line conditions that have to be correct for a fax machine to pick up. 1 is the phone line voltage, 2 is the phone line current, 3 is what is called decibel loss.
          The reason you can send and call out on the line is that you manually turn "on" the phone line when you pick up the phone or when you select send on a fax, it is manually switching a relay to connect to the phone line.
          When you are receiving you need the correct signal level to activate the fax. Think of how it is when your TV/VCR remote has weak batteries. You press the button and sometimes it works most of the time it doesn't. The volatge on the battery will still read 1.5 volts, but you dont have enough current draw or wattage to get the proper signal to change channels or turn the sound up and down. Same concept. But when you walk up to the TV/VCD you push the buttons it works fine. Very same concept.
