How to troubleshoot fax issues on Dell Multifunction Laser Printers


Confirm the Telephone Line is Functional

  1. Disconnect the fax cable from the the telephone wall socket.
  2. Using a telephone handset, confirm outbound calls can be made and inbound calls answered.
  3. If you are unable to make/receive calls, or there is excess noise on the line contact your service provider to resolve.

Compatibility with Voice Over Internet Protocol (VoIP) or Private Branch Exchange (PBX) systems cannot be guaranteed. Whenever possible test the suspect device using a standard Public Switched Telephone Network (PSTN) fixed line.
