    Yes same problem. I am suspecting my VOIP line quality and will try to lower transmission speed. I have already set the FAX in "OVERSEAS" mode hoping this might deal with the issue. No luck yet.

    I am having the same problem but on a different machine. The brother manuel says it is a poor quality phone line problem and to try again. I've tried 3 times and still no luck.

Hp laser jet m1536dnf MFP won't send fax comm error 388


You can start by making sure that the photocopy is working, this is to ensure that the scanner is working. Next, try to isolate the issue if this is only happening to only one fax number? If all of these have negative results, I suggest for a hardware reset. Follow the steps for reset found here, How to Reset the HP LaserJet Pro M1536dnf Multifunction Printer. Goodluck :)

Sending fax for hp all in one indicate Comm Error 388


Error could be caused by the fax machine that you are sending to.
So you can receive faxes, but can't send them. Is it just the one number that causes the error, or is it all faxes sent that cause the error?
What I like to do on fax troubleshooting calls, is to call the phone company that the site is using. Tell them that you are having fax problems, and ask them to test the line.

Not receiving any Fax, only can send out Fax.


Hi Mechanic.

The problem could be with your phone service if you are on digital lines, you would have to install a digital to analog filter. If you are analog the comm errors are typical of a line with a lot of static. You can change two settings on the printer which should solve the issue until you install a filter.

The two settings which are under the fax set up menu/ all faxes\
Error correction mode (ECM) set it to off
Fax Speed set it to medium.

Good luck

Error codes 283 and 232 in received Faxes


basically error 232 indicates that a communication failure has occurred between the two machines
Following these steps may help resolving your issue

1. Make sure that the phone cord is plugged directly from the wall jack into the back port of the fax machine that is marked "Line" or "To Wall Jack", or that has a wall-jack symbol.
2. Verify that the line interface unit (LIU) (the box that the phone cord plugs into) is seated fully into the back of the fax.
3. Remove any other device from the line such as splitters, credit card machines, or telephone answering machines, and retry the fax communication.
4. Try sending and receiving faxes on a different fax line.
5.Try using a different telephone cord.
6. Have the phone company test your line for static or noise problems.
7. Disable Error Correction Mode (ECM) if the same error occurs repeatedly.

Hope this helps.
thx

Have voip and brother mfc 7420. error code 2001 and 2006


Get a new phone wire. Put a phone on the line and listen for static. Too many phones on one line will cause problems. If the phone line is going thru a surge protector, check the quality of the sound with it and without it, it may be damaged. Keep power wires away from phone wires, they cause static.

Laserjet 3330 is resulting in fax Comm Errors 327, 232, 442, 356, 421 Comm Error 327 is always with fax # 780.467.6516. i can not fax to this number and when i receive from it, it always prints a Fax...


232-A communication failure has occurred between the two machines.
327-*Reattempt the fax reception at a different time when telephone line conditions have improved. Call the telephone provider if line conditions fail to improve.
356-The remote user has pressed the Stop key, causing the session to be aborted.
442-An error occurred during transmission after one or more partial pages had been sent. The transmitting machine was unable to restart the control channel (handshaking) before sending more data. This error typically occurs when the receiving fax disconnects after receiving part of a page but can also occur if the receiving fax is using a fax format that is incompatible with the HP fax machine (usually during color faxing).

Fax sending problem


It sounds like you have a few problems. First, the comm error usually means there was a problem communicating with the other fax. This maybe caused by a phone line issue, or a bad connection. You will have to replace you ink but that does not have anything to do with your sending issues. As far as the pages getting stuck, the separation pad under the top cover should be cleaned. If you lift up the cover where you load your pages to be sent, and look in there(on the backside of the keyboard)you will see a flat square rubber piece. Clean it thoroughly with a rag and some rubbing alcohol. Also clean the rubber rollers as well. Good luck John
