I've been trying to send a fax to an office in Sri Lanka for several days now, but it won't go. We are getting a Comm Error 388 in the fax error report. The unusual thing is we are able to send fax messages to other numbers (either locally or internationally), and we are able to receive fax messages from the Sri Lanka office. Can you please suggest a solution? Appreciate your urgent feedback.

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 :)

It makes no sense that the dealer cannot find the problem. There are several areas they could be looking at and are not. The service manual is available,

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.

Hi,

The reason for the error code:
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.

there is not error code for the OfficeJet 4315. however, there are similar code for other Hp printer.
error "388" is lised as unable to detect T30 frames. in other words, the machine fail to establish comparable connection. this can be the machine trying to send out fax in high speed, or the phone line problem.
consult the user manul how to set a lower transmission rate, or try to send the fax at a differnt time of the day . If that still give you problem, please call the phone company and have they look a the phone line.

your country code is wrong.The country code of Sri lanka is 0094

error code 388 says :-
Unable to complete the handshake.

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