You might want to post this on the fax board as this is regular fax and not eFax.
If I solved your post please mark it as solved to help others.
I'm a printer tech with HP.

According to the error code that you are receiving, there is too much noise on the phone line to establish a valid connection between the two fax machines. The only solution listed for this error is to wait and try again later to see if the line condition might have improved or to contact your phone company and let them know that you are experiencing this issue.
Here are a few things I would try first though.
1. Press the right arrow and go into the setup menu.
2. Select the Fax Menu
3. Select Advanced Fax Setup
4. Turn Error Correction Mode (ECM) off
5. Set Fax Speed to slow
Changing those settings seems to resolve a lot of faxing issues, but if after trying those steps you continue get that error code or even another one, it is more than likely an issue with your fax line or the recieving fax line.
Here is a link with all the fax error codes, their description, and suggested solution:

HI, I am having the same problem right now. I have had this fax for only a couple months and this is the first time this has happened. I just tried your fix but it did not work for me. Any other suggestions? Thank you!

I understand you are receiving "Error 388" when sending a fax. What type of printer do you have? Click here to find out: Model Number.
I will provide a HP document on Interpreting Error Codes in Fax Communication.
If you have preformed all the troubleshooting steps from this document, then please contact your Telephone provider since the line conditions are not improving.

Thanks for posting the link to the error message listing. FYI - nothing there was of any assistance to me. However, when I changed 2 low ink cartridges (cyan and magenta), I was able to fax without a problem. Note: I had not received any warnings of "low ink", AND I was trying to fax in black - so why should 2 low ink color cartirdges interfere with that?! I just sent a message to HP with these details.
Again, thanks for your help.
