HP LaserJet MFP Analog Fax Accessory 300 - Error Numbers

When an error occurs, a specific error number will be generated. If a problem occurs in the Analog Fax Accessory or in the sending/receiving of a fax, an error number (or error code) is generated and are shown in the Fax Activity Report, Fax Call Report, and the T.30 Trace. Print one of these reports to see the error number associated with the last fax call. The error number is shown in parentheses after the text in the “Result” column. No number is given if the result is “Success”.

Example of error in Result column: Communication Error (17)

From the Control Panel, the Fax Reports can be found under Menu, Fax, Reports and the T.30 trace can be found under Menu, Fax, Service.

A T.30 trace is a specialized report that gives a detailed breakdown of the call content and progress. The content and use is beyond the scope of this paper, however if a problem persists and help from service personnel is necessary, the information in the T.30 trace may be helpful to the service personnel in diagnosing the problem.

A standard fax transmission can be broken into 5 distinct phases. The tables below reference these phases and give an indication as to the extent of the call progress.
  • Phase A: Call Setup - The fax machines go "off hook" and identify themselves as fax machines.
  • Phase B: Pre-Message Procedure - Exchange and negotiation of capabilities of each fax machine.
  • Phase C: Message Transmission - Actual exchange of data.
  • Phase D: Post-Message Procedure - Confirmation that message was received.
  • Phase E: Call Release - The call is ended and the machines disconnect.

Error code organization

Phase A errors are associated with the call placement and initial connection. Phase B errors are usually associated with a compatibility issue between two fax machines or a firmware issue. Phase C errors are usually associated with noise on the phone line or a dropped phone line from the other fax machine. There may not be an error associated with every consecutive number as many numbers are held in reserve and not used. The error codes are organized as shown in the following table:

Error No. (or Range)

Errors associated with call origination

Error
Cause
Corrective Action
17
No DIS frame heard on a non-V.34 call
Make sure the remote number is to a fax machine.
32-47
General Phase B transmit error
Upgrade firmware if problem persists.
37
No response heard to DCS/TRN sequence
Try call again.
39
Failure to train at minimum speed
Adjust minimum speed lower if it is set above 2400.
67
Underflow error when sending page
Upgrade fax machine firmware to keep modem supplied with data while sending.
82, 84, 86
No response heard to end of page message (MPS/EOP/EOM) respectively
Try call again.
224
General state timeout
Try call again.

Errors associated with call answering

Error
Cause
Corrective Action
17
No DCS frame heard in response to DIS frames.
Probably a voice call, retry call.
112-117
General Phase B receive error.
Upgrade firmware if problem persists.
145
No scan line received in non-ECM mode for 12 seconds.
Use ECM mode if possible, otherwise, upgrade firmware if problem persists.
160-175
Error when receiving page data.
Disabling ECM mode could help with errors that occur when ECM connections are made. Also disabling V.34 could help as well (but probably not much at this point).
