Interpreting Error Codes in Fax Communication Error or Fax History Reports

  • PrintPrint
This document applies to HP fax machines and printers with fax capability that display or print an error code when a fax fails.
A fax communication error report or fax history report might contain error codes to help you diagnose fax issues. You can find the error code definitions and solutions in the tables at the end of this document.
The following list contains troubleshooting tips you can try to resolve errors. If errors occur every time a fax is sent or received, there might be more important communication issues. For more helpful information about troubleshooting fax issues see Troubleshooting Fax Transmission and Reception Issues (in English).
Check the following items:
  • Make sure that you have plugged the phone cord directly and securely into the wall jack and into the back port of the fax product. The fax port on your product is marked "Line," "To Wall Jack," or with a wall jack symbol.
  • Make sure the Line Interface Unit (box that the phone cord plugs into) is fully seated into the back of the fax product.
  • Remove any other devices from the line such as splitters, credit card machines, or telephone answering machines.
  • Try sending and receiving faxes on a different fax line.
  • Try using a different telephone cord.
  • Have the phone company test your line for static or noise problems.
  • Turn Error Correction Mode (ECM) off, if you encounter the same error repeatedly. Click this link HP All-in-One and Fax Products for more information on enabling or disabling ECM.
    NOTE: Error codes that apply specifically to ECM have ECM listed next to them.

Interpreting fax receive error codes

The following tables contain fax receive error codes. An error code can have more than one definition (cause), and more than one solution.
Error CodeDefinitionsSolutions
200The fax session completed without errors. No action required
Error CodeDefinitionsSolutions
221The user pressed the Stop key, causing the fax session to be prematurely terminated. Contact the remote caller and have the fax sent again.
Error CodeDefinitionsSolutions
222The local machine answered a call, but is unable to detect the presence of a calling fax machine. Typically this is because the local fax machine answered a voice call. Confirm that the remote caller is a fax machine and not a voice call.
The remote user canceled the fax transmission by pressing the Stop key immediately prior to, or just as the local machine answered the call.If the remote machine ends the call just as the local machine starts reception, reduce the ring count on the local machine answering setting. As an alternative, suggest that the sender manually fax the document.
The receiving fax machine is an older silent fax machine. Try turning on Silent Detect in the Fax settings. Confirm that the sender is not inadvertently attempting to poll the local machine for a document, instead of sending to the local machine.
The remote machine automatically ended the call immediately before, or just as the local machine answered the call.Select a slower reception speed.
The remote (calling) fax machine determined that there was a feature incompatibility between the two machines. The remote machine disconnected immediately before sending any further fax tones or T.30 frames. This situation occurs rarely. Reconfigure the local fax machine to use different configuration settings, enable or disable the ECM setting.
Error CodeDefinitionsSolutions
223 ECM

224
The local machine was unable to receive an entire page even after multiple attempts to receive the parts of the page that contain errors. This situation is usually due to extremely poor line conditions. Try to receive the fax when telephone line conditions have improved
Disable ECM. Errors could still occur, and might result in degraded image quality on the received page. However, the ability to receive the entire document will improve.
Select a slower reception speed.
Error CodeDefinitionsSolutions
225The remote machine attempted to initiate a remote diagnostic session with this machine even though remote diagnostic access is locally disabled.Enable the remote diagnostics capability on the local machine, if available. Otherwise, ask the sender to remove the fax number from the diagnostic check.
Error CodeDefinitionsSolutions
226The remote machine attempted to initiate a remote diagnostic session with this machine. However, the remote diagnostic versions that are supported by the two machines are incompatible.Remote diagnostics cannot occur between machines with incompatible remote versions. Ask the sender to remove the fax number from the diagnostic check.
Error CodeDefinitionsSolutions
227The remote machine attempted to initiate a fax session at a speed and modulation that the local machine does not support.Ask the sender what speed the fax machine is using to send, and then reconfigure the local machine to receive at that speed, if possible. Otherwise, ask the sender reconfigure the remote machine to send at a compatible speed.
Error CodeDefinitionsSolutions
228The remote machine attempted to initiate a poll transmission from the local machine even though the local machine is not configured for poll transmission.Confirm that the remote user wants to initiate a poll transmission. It is possible that the remote user inadvertently attempted to poll. If this is the case, ask the sender to retry a normal transmission from the remote machine.
If you want remote polling, confirm that you have correctly configured the local machine for poll transmission.
Error CodeDefinitionsSolutions
229The remote machine attempted to initiate a secure poll transmission from the local machine but did not provided a valid password.Confirm that the remote user has the correct password, and that the local machine is configured with the same password, if this option is available.
Error CodeDefinitionsSolutions
230The remote machine attempted to initiate an operation that requires error correction, but did not select error correction for the session. Enable ECM on both the local machine and the remote machine.
Error CodeDefinitionsSolutions
231The remote machine attempted to initiate a transmission to the local machine, but the receive capability was disabled at the local machine. Make sure that paper is loaded correctly, paper is not jammed within the machine, and any other system errors have been cleared.
Error CodeDefinitionsSolutions

235 ECM

236 ECM

237
A communication failure occurred between the two machines.If the error persists, and error correction is in use for the fax session, disable ECM. Fax quality might be degraded.
The user at the remote machine might have pressed the Stop key. Set the host machine to receive at a slower transmission speed.
The call waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line. Do not use call waiting on a line with a fax machine.Retry the fax reception when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve. These errors can occur if the phone lines in the area to be faxed are old or there is noise (static on the phone line). Other reasons can include power brownouts and other power-related problems.
The power at the remote machine was interrupted, or deliberately turned off causing the fax session to be interrupted.
Error CodeDefinitionsSolutions

239 ECM

240 ECM

241 ECM
The sending fax machine sent an unexpected communication. This is usually a defect in the remote sending machine. If ECM is enabled, then disable it.
Have the sender send from a different fax machine to see if the error clears.
Error CodeDefinitionsSolutions
242The remote fax machine is attempting to receive instead of send. Both machines have attempted to start a reception at the same time. On many fax machines, it is possible to accidentally initiate a fax reception in the following cases:

  • There is no paper in the machine.
  • The paper is not correctly loaded and the document sensor cannot sense it.
Contact the sender to make sure that a document is ready and correctly loaded in the sending fax machine. Also make sure that the remote machine is attempting to initiate a transmission and not a reception.
Error CodeDefinitionsSolutions
243

244
The user of the remote machine pressed the Stop key, causing the session to be prematurely terminated.Make sure that the remote machine can accept and use polling.
Select a slower reception speed.
The remote fax machine determined that there was a feature incompatibility between the two machines and terminated the session. For example, the local machine wanted to initiate polling, but the remote machine did not support this mode of operation. Reconfigure the local fax machine to use different configuration settings, enable or disable the ECM setting.
Error CodeDefinitionsSolutions
245 ECM

246 ECM
The user of the remote machine pressed the Stop key, causing the session to be prematurely terminated.If the document is large, ask the remote user to re-send the document as two or more smaller documents.
Have the sender send at a lower resolution.
The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line. Disable ECM, and then try to receive the fax again.
The local machine held the remote machine during reception of a large or complex document due to lack of available memory. This hold time exceeded the timeout (typically 60 seconds) used by the remote machine, and it terminated the session.

251 ECM
The remote machine appears to be locked.Ask the remote machine user to reset the remote machine.
Set the local machine to receive at a lower transmission speed.
Turn both the sending and the receiving machine off for ten seconds, turn them on, and then try sending again.
If faxes are successfully sent to and received from other machines, but not this particular remote machine, then the issue is probably a problem with the remote machine.
Error CodeDefinitionsSolutions
252Telephone line conditions were too poor to receive a fax. Retry the fax reception when line conditions might have improved.
Configure the machine to start reception at a lower speed.
If the local machine received several pages of a larger document successfully, ask the remote user to send the document in several smaller parts.
Error CodeDefinitionsSolutions
253The remote machine attempted to initiate a page transmission using a page width that is not supported by the local machine. Ask the remote user to reconfigure the sending fax machine to send using a standard (letter or A4) page width.

The telephone connection was lost or disconnected.Retry the transmission.
If the error persists, and error correction is in use for the fax session, disable ECM.
Set the host machine to receive at a slower transmission speed.
There was a communication error with the sending fax machine. Retry the fax reception when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error CodeDefinitionsSolutions

292
The received fax could not be stored. Note the remote machine's number and any fax information. Turn the power off to the product for 10 seconds, then turn the power back on. Ask the remote machine user to resend the fax.
Ask the remote machine user to send at a lower resolution setting.
If it still fails, try receiving a fax from another machine.
If the local machine consistently gives this error code from different fax numbers, then the issue is probably hardware related and the machine should be replaced or serviced.

Interpreting fax send error codes

The following tables contain the fax send error codes. An error code can have more than one definition (cause), and more than one solution.
Error CodeDefinitionsSolutions
300The fax session completed without errors No action required
Error CodeDefinitionsSolutions
311The user of the local machine pressed the Stop key, causing the session to be prematurely terminated before all pages have been sent. Try sending the fax again
Error CodeDefinitionsSolutions
312A remote fax machine failed to answer the call. Specifically, fax tones or the fax handshake (connection) from the remote machine was not detected. This is usually caused by one of the following reasons:

  • The user called the wrong number.
  • The user called the correct number, but the machine was configured not to answer,
  • The remote machine temporarily disabled answering due to a condition such as lack of paper or a paper jam.
Confirm that the remote fax machine is ready to receive a document, and then try sending the fax again.
Error CodeDefinitionsSolutions
313A busy signal was detected each time the local machine attempted to call the remote machine.Retry the fax transmission when the line is no longer busy.
Error CodeDefinitionsSolutions
314The local machine attempted to initiate a remote diagnostic session, but detected that remote diagnostics are disabled on the remote machine. Enable remote diagnostics on the remote machine, if available.
Error CodeDefinitionsSolutions
315The local machine attempted to initiate a remote diagnostic session, but detected that the remote diagnostic version supported by the remote machine is incompatible.No solution is available. Remote diagnostics cannot occur between machines with incompatible remote versions.
Error CodeDefinitionsSolutions
316The local machine is set to initiate document transmission, but detected that the remote machine is not able to receive a document. This error is very rare because normally a remote machine will not answer if it cannot receive a document. One of the few exceptions to this would occur if the remote machine was configured to poll transmit a document, but was unable to receive.Configure the remote machine for reception. The remote user should make sure paper is loaded in the machine, paper jams are fixed, and any error messages are cleared.
Error CodeDefinitionsSolutions
317The remote machine cannot support a fax reception at any speed or modulation that is supported by the local machine. No solution is available because the two machines are incompatible.
Error CodeDefinitionsSolutions
318The remote machine cannot support a fax reception at the page width selected by the local machine. Reduce or enlarge the page size setting on the local machine to a size supported by the remote machine.
Error CodeDefinitionsSolutions
319The local machine attempted to initiate a binary file transfer (BFT), but detected that the remote machine does not support this mode of operation.Enable the BFT capability on the remote machine if supported.
Resend the document as a normal fax, rather than attempting a BFT transfer.
Error CodeDefinitionsSolutions
320The local machine is set to initiate poll reception with a remote machine, but detected that the remote machine is not configured to do this. Poll transmission from a remote machine is typically configured with each fax session.Confirm that the local user really wants to attempt a poll reception. If not, reconfigure the local machine for a normal fax transmission.
Configure the remote machine for poll transmission. The remote user must load a document to send before configuring the machine for polling.
