I am receiving a fax error code but don’t know what it means

When a fax fails, it might give you a fax error code consisting of two characters (such as 37 or 4A), instead of telling you what the actual problem is in plain English.

An example would be¬† ‚ÄúCommunication Error (37)”.

The code has a purpose and meaning, and you may check it is against the fax error code table.

The error code table is available here
