Bad Drum Unit

Try calling your fax machine from a cell phone. If the fax doesen't answer, or if the line is busy, the phone line may be bad. Also check that the phone line to the fax is plugged into the receptical marked LINE, not PHONE. The PHONE receptical is to connect a telephone to the fax machine. If it still does not answer, try going into the fax menu and go to RECEIVE settngs. Try changing each setting, then call the fax with the cell to see if it answers. Write down each setting before you change it, so you can set it back if changing it does not solve the problem.

sounds like you have a door or switch open. Some models have a door in the back that you can open and receive the faxes in the back of the machine, others have a lever.

If its not constant its probably on there end. Does it happen with any other party. Lawrence
