Interpreting Error Codes in Fax Communication Error or Fax History Reports

  • PrintPrint

Introduction

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 some basic troubleshooting tips you can try to resolve errors. If errors occur every time a fax is sent or received, there might be larger communication issues. Click here for more help with fax communication issues (buu02151) (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 the fax receive error codes. An error code can have more than one definition (cause), and more than one solution.
Error Code: 200
Definition

The fax session completed without errors.
Error Code: 221
Definition

The user pressed the Stop key, causing the fax session to be prematurely terminated.
Error Code: 222
Definitions
  • The 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.
  • The remote user canceled the fax transmission by pressing the Stop key immediately prior to, or just as the local machine answered the call.
  • The receiving fax machine is an older silent fax machine. Try turning on Silent Detect in the Fax settings.
  • The remote machine automatically ended the call immediately before, or just as the local machine answered the call.
  • 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.


Solutions
  • Confirm that the remote caller is a fax machine and not a voice 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.
  • Confirm that the sender is not inadvertently attempting to poll the local machine for a document, instead of sending to the local machine.
  • Select a slower reception speed.
  • Reconfigure the local fax machine to use different configuration settings, enable or disable the ECM setting.
Error Codes: 223 ECM, 224
Definition

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.

Solutions
  • Try to receive the fax at a different time 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 Code: 225
Definition

The remote machine attempted to initiate a remote diagnostic session with this machine even though remote diagnostic access is locally disabled.

Solution

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 Code: 226
Definition

The 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.

Solution

Remote diagnostics cannot occur between machines with incompatible remote versions. Ask the sender to remove the fax number from the diagnostic check.
Error Code: 227
Definition

The remote machine attempted to initiate a fax session at a speed and modulation that the local machine does not support.

Solution

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 Code: 228
Definition

The remote machine attempted to initiate a poll transmission from the local machine even though the local machine is not configured for poll transmission.

Solutions
  • 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 Code: 229
Definition

The remote machine attempted to initiate a secure poll transmission from the local machine but did not provided a valid password.

Solution

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 Code: 230
Definition

The remote machine attempted to initiate an operation that requires error correction, but did not select error correction for the session.

Solution

Enable ECM on both the local machine and the remote machine.
Error Code: 231
Definition

The remote machine attempted to initiate a transmission to the local machine, but the receive capability was disabled at the local machine.

Solution

Make sure that paper is correctly loaded, paper is not jammed within the machine, and any other system errors have been cleared.
Error Code: 232, 233, 234, 235 ECM, 236 ECM, 237
Definitions
  • A communication failure occurred between the two machines.
  • The user at the remote machine might have pressed the Stop key.
  • 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.
  • The power at the remote machine was interrupted, or deliberately turned off causing the fax session to be interrupted.


Solutions
  • If the error persists, and error correction is in use for the fax session, disable ECM. Fax quality might be degraded.
  • Set the host machine to receive at a slower transmission speed.
  • Retry the fax reception at a different time 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.
Error Code: 238, 239 ECM, 240 ECM, 241 ECM
Definition

The sending fax machine sent an unexpected communication. This is usually a defect in the remote sending machine.

Solutions
  • If ECM is enabled, then disable it.
  • Have the sender send from a different fax machine to see if the error clears.
Error Code: 242
Definition

The 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.


Solution

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 Code: 243, 244
Definitions
  • The user of the remote machine pressed the Stop key, causing the session to be prematurely terminated.
  • 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.


Solutions
  • Make sure that the remote machine can accept and use polling.
  • Select a slower reception speed.
  • Reconfigure the local fax machine to use different configuration settings, enable or disable the ECM setting.
Error Code: 245 ECM, 246 ECM
Definitions
  • The user of the remote machine pressed the Stop key, causing the session to be prematurely terminated.
  • The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line.
  • 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.


Solutions
  • 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.
  • Disable ECM, and then try to receive the fax again.
Error Code: 247, 248, 249 ECM, 250 ECM, 251 ECM
Definition

The remote machine appears to be locked.

Solutions
  • 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 Code: 252
Definition

Telephone line conditions were too poor to receive a fax.

Solutions
  • Retry the fax reception at a later time 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 Code: 253
Definition

The remote machine attempted to initiate a page transmission using a page width that is not supported by the local machine.

Solution

Ask the remote user to reconfigure the sending fax machine to send using a standard (letter or A4) page width.
Error Code: 281, 282 ECM, 283, 284, 285 ECM, 286
Definition

The telephone connection was lost or disconnected.

Solutions
  • 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.
  • Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error Code: 290
Definition

There was a communication error with the sending fax machine.

Solution

Use solutions for Error Codes 281, etc., in the previous table.
Error Code: 291, 292
Definition

The received fax could not be stored.

Solutions
  • 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 Code: 300
Definition

The fax session completed without errors
Error Code: 311
Definition

The user of the local machine pressed the Stop key, causing the session to be prematurely terminated before all pages have been sent.
Error Code: 312
Definition

A remote fax machine failed to answer the call. Specifically, fax tones or the fax handshake (connection) from the remote machine was not detected. Tthis 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.


Solution

Confirm that the remote fax machine is ready to receive a document, and then try to send the fax again.
Error Code: 313
Definition

A busy signal was detected each time the local machine attempted to call the remote machine.

Solution

Retry the fax transmission at a later time when the line is no longer busy.
Error Code: 314
Definition

The local machine attempted to initiate a remote diagnostic session, but detected that remote diagnostics are disabled on the remote machine.

Solution

Enable remote diagnostics on the remote machine, if available.
Error Code: 315
Definition

The local machine attempted to initiate a remote diagnostic session, but detected that the remote diagnostic version supported by the remote machine is incompatible.

Solution

No solution is available. Remote diagnostics cannot occur between machines with incompatible remote versions.
Error Code: 316
Definition

The 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.

Solution

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 Code: 317
Definition

The remote machine cannot support a fax reception at any speed or modulation that is supported by the local machine.

Solution

No solution is available because the two machines are incompatible.
Error Code: 318
Definition

The remote machine cannot support a fax reception at the page width selected by the local machine.

Solution

Reduce or enlarge the page size setting on the local machine to a size supported by the remote machine.
Error Code: 319
Definition

The local machine attempted to initiate a binary file transfer (BFT), but detected that the remote machine does not support this mode of operation.

Solutions
  • Enable the BFT capability on the remote machine if supported.
  • Resend the document as a normal fax, rather than attempting a BFT transfer.
Error Code: 320
Definition

The 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.

Solution
  • 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.
Error Code: 321, 322, 323, 324
Definition

There was a communication error with the receiving fax machine due to poor telephone line conditions.

Solution
  • Set the receiving machine to receive at a slower transmission speed
  • If the session fails after sending several pages of a large document, resend the document as several smaller documents.
  • Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error Code: 325 ECM, 326 ECM, 327 ECM, 328 ECM
Definition

Telephone line conditions were very poor.

Solution
  • Try to send the fax at a different time when telephone line conditions have improved.
  • Disable ECM. Errors might still occur, and might result in a degraded image quality on the received page. However, the ability to send the entire document will be improved.
  • Re-attempt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error Code: 329, 330, 331
Definition

The remote machine reported that one or more pages were received (non-ECM mode) with excessive errors. This error does not result in the session being terminated immediately. Subsequent page transmission can still occur and later pages can be received without error.

Solutions
  • Retry the fax transmission at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
  • Enable ECM.
  • Select a lower speed for the initial transmission speed.
Error Codes: 332, 333, 334, 335, 336, 337, 338 ECM, 339 ECM, 340 ECM, 341 ECM, 342 ECM, 343
Definition

The remote fax machine might be defective.

Solutions
  • Try to verify this by sending the same fax to other fax machines. If these transmissions are successful, then notify the user of the remote machine to make them aware of the issue.
  • If the fax fails when sending to other machines, turn it off for 10 seconds, turn back on, and then try sending again.
Error Code: 344, 345, 346, 347, 348, 349 ECM, 350 ECM, 351 ECM, 352 ECM, 353 ECM, 354, 355
Definitions
  • The remote machine failed to respond to a fax command from the local machine because the connection was interrupted. 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 outages and other power-related problems.
  • The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line.
  • The remote user pressed the Stop key while the reception was in progress.
  • Under rare conditions, incompatibility between the two machines might cause the remote machine to abandon the call.


Solutions
  • Retryt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
  • Disable ECM. Errors might still occur, and might result in a degraded image quality on the received page. However, the ability to send the entire document will be improved.
  • Try sending at a lower transmission speed.
Error Code: 356, 357, 358, 359, 360, 361, 362 ECM, 363 ECM, 364 ECM, 365 ECM, 366 ECM
Definitions
  • The remote user pressed the Stop key, causing the session to be terminated.
  • The remote machine encountered a system problem such as no paper or a paper jam. This prevented the fax from receiving any more pages, and caused it to terminate the session prematurely.
  • The call-waiting service can cause this error. The click, heard for an incoming call, is actually a momentary disconnect of the line.
  • The remote machine encountered an incompatible feature causing it to terminate the session.


Solutions
  • Configure the remote machine for document reception by clearing any paper jams, loading sufficient paper, and clearing any other error messages.
  • Configure the local fax machine to use a slower reception speed.
  • Enable or disable the ECM setting.
Error Codes: 367, 368, 369, 370, 371, 372, 373 ECM, 374 ECM, 375 ECM, 376 ECM, 377 ECM, 378, 379
Definition

The remote machine appears to be locked.

Solutions
  • Ask the user of the remote machine to turn it off for 10 seconds, and then turn it back on. Retry the transmission.
  • Send to another fax machine to make sure the issue is with the one specific remote machine.
Error Code: 380 ECM
Definition

The remote machine failed to issue a valid response to a CTC frame. This occurs during ECM transmission after trying repeatedly to send a fax.

Solutions
  • Disable ECM, and then try faxing again.
  • There might be no solution because the remote machine could be defective.
Error Code: 381 ECM
Definitions
  • The remote machine failed to respond to a fax command from the local machine because the connection was interrupted.
  • The remote user pressed the Stop key while the reception was in progress.


Solutions
  • Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
  • Disable ECM, and then try faxing again.
Error Code: 382 ECM
Definition

The remote fax machine held the local fax machine from continuing the ongoing transmission because of a temporary low memory condition at the remote machine. If this holding period exceeds a machine’s specific timeout value, the session is terminated.

Solutions
  • Resend at a lower resolution.
  • Resend the document as two or more separate fax transmissions. Wait several minutes between the end of one transmission and the start of the next transmission.
Error Code: 383 ECM
Definitions
  • The remote machine failed to respond to a fax command from the local machine because the connection was interrupted.
  • The remote user pressed the Stop key while the reception was in progress.


Solutions
  • Disable ECM, and then try faxing again.
  • Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error Code: 384
Definition

The local machine attempted a black JPEG transmission to a machine that does not support this mode.

Solution

Try to send the fax using a different mode.
Error Code: 386, 387, 388, 389, 390, 391, 392, 393, 394, 395
Definition

There is too much noise on the line for a valid connection between two fax machines to complete. The noise problem might go away over time.

Solution

Retry the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
Error Code: 396, 397, 398, 399, 400, 401, 402, 403, 405, 406, 407, 408, 409, 410, 411, 412, 413, 414, 415, 416, 417, 418, 419
Definition

During a V.34 transmission, the local machine is unable to connect (handshake) with the remote machine and is consequently unable to send a T30 frame. This occurs when the line is disconnected or if line conditions degrade during the session.

Solutions
  • Remove any pass-through devices from the phone line, and then try the fax again.
  • Confirm that the fax/phone cable is no longer than required, and that it does not pass near unshielded electric motors such as fans, heaters, or household appliances.
  • Try to send the fax at a different time when telephone line conditions have improved.
Error Code: 420, 421
Definition

A handshaking (connection) error occurred at some point in the process from the sending fax machine.

Solutions
  • Try the fax at a different time when telephone line conditions have improved.
  • In some cases this error can occur if the other fax machine is using a fax format incompatible with the HP fax.
Error Code: 422, 423
Definition

A handshaking (connection) error occurred at some point in the process from the receiving fax machine.

Solutions
  • Try the fax at a different time when telephone line conditions have improved.
  • This error can occur if the other fax machine is using a fax format incompatible with the HP fax product (usually during color faxing).
Error Code: 430
Definition

The sending fax is unable to send continuous tones after sending the control data and before sending the fax data to the receiving fax. This error might be associated with bad line conditions or might indicate a problem with the fax's modem.

Solutions
  • Try the fax at a different time when telephone line conditions have improved.
  • Have the the telephone company check the line.
Error Code: 431
Definition

The sending fax machine did not receive a response after terminating a transmission. This might occur naturally depending on when the fax session is terminated.

Solutions
  • if the fax was intentionally terminated, no action is required.
  • Try the fax at a different time when telephone line conditions have improved.
Error Code: 440, 441, 442, 443, 444
Definition

An error occurred during transmission after one or more partial pages were sent. The sending machine was unable to restart the control channel connection(handshake) before sending more data. This error typically occurs when the receiving fax disconnects after receiving part of a page. It can also be caused if the receiving fax is using a fax format incompatible with the HP fax (usually during color faxing).

Solution

Try the fax at a different time when telephone line conditions have improved.
