Fax Error Codes

Although it is often difficult to narrow down exactly why a fax fails, our goal is to provide you with as much information as is available to determine why your fax did not go through.  Here is a list of our error reason codes:

• 1000 = fax pending
• 4000 = fax failed
• 5000 = fax resource issue
• 5100 = fax request blocked
• 5200 = fax document render issue - permanent fail
• 6000 = fax connect failed
• 6100 = fax number busy
• 6200 = fax machine not answering
• 6300 = fax detection failed
• 6400 = fax pickup failed
• 6500 = fax detection failed
• 6600 = fax detection timeout
• 6800 = fax negotiation failed
• 7000 = fax training failed
• 8000 = fax transmit failed
• 9000 = fax failed

Most often the errors reside in the 6000 block, usually as a result of being unable to connect successfully with the remote fax machine or service.  This can be because of a busy or unavailable line, poor line quality, a bad connection, an old fax machine, etc.
