You could try these two suggestions from HP support. The semi-full reset will affect quite a few settings. Perhaps you should copy down these settings for reference later.

The answer mode determines whether your HP All-in-One answers incoming calls or not.
• If you set the HP All-in-One to answer faxes automatically, the HP All-in-One will answer all incoming calls and receive faxes. Set the Auto Answer setting to On. • If you set the HP All-in-One to answer faxes manually, you must be available to respond in person to the incoming fax call or your HP All-in-One will not receive faxes. Set the Auto Answer setting to Off. For more information on receiving faxes manually, see Receive a fax manually. If you do not know which answer mode to use, see Choose the recommended answer mode for your setup.
To set the answer mode 1 Press Setup. 2 Press 4, and then press 2. This selects Basic Fax Setup and then selects Auto Answer.
3 Press right arrow to select On or Off. 4 Press OK to accept the setting.

Is tel line going into correct socket of fax? (Line not Ext.)

 

Is Fax set to auto answer or manual?

 

If you pick up line or press speaker button can you hear other fax sending if so press start and hang up you should receive fax, and you have just proven that machine is in manual receive mode!

 

I think you will find it  will wake from sleep automaticly if setup correctly.

It does not matter, it should wake up as soon as a fax is coming in, the problem is most likely that the fax set-up was improperly done. There should be a setting to tell it when to pick up, after two,three or four rings, if you have an answering machine, time date. Those need to be set-up for it to work.
