HP MFP fails to receive faxes occaisionally

Hello everyone, thanks for taking the time to read my question. About 20% of the time, our MFP M525 will fail to receive a fax . It is an intermittent error, the receive duration varies, the time of day varies and the frequency varies.  When it fails an error shows up in the Event Log of the printer: failed(70) . I can't find on online resource that will tell me what the 70 stands for, does anyone know? Or failing that, does anyone have an idea about what would cause receiving to fail intermittently?  I have replaced it with an older Brother fax machine and it doesn't have problems receiving, so I know it's the machine and not the line.

I don't know what the code means but I have had problems over the years with HP Faxes on MFPs not working properly with some fax modems.  I only use modems that have the Rockwell chip set now and they seem to always work with the HP machines.

That indicates a communications error.  You can try disabling Error correction mode and see if that resolves this issue.  Here is how you do that:

On the control panel, scroll to and touch the Administration icon to open the Administration menu.
Touch Initial Setup to open the setup settings menu and then touch Fax Setup.
Touch Fax Send Settings to see the settings.
Touch Error Correction Mode to see the settings.
Touch Enabled (default) to enable error correction mode, or touch Disabled to disable correction mode.

hope this helps!
