at right side you can remove cover for the memory, remove it and clean contact, or else you need to replace it.

This message usually shows up when you've received many faxes and haven't printed them, or when you have attempted to send faxes but they never made it and were kept in memory for a later date.
I would search in your user's manual how to clear the memory, since each manufacturer has a different way to do this, and the machine's menuing systems also differ from one manufacturer to another.
Good luck!

Bad control panel. Xerox will replace for free (800 635 8100) call and ***** to get it for free (They had a "LOT" of defective panels)

User installable.

Once you press menu #1934 you have to then press the machine status button then scroll to maintenance, then scroll to clear memory. Once you do that repeat entering the tech mode, press machine status, maintenance and perform a shading adjustment with 5 pieces of paper on the glass, that will recalibrate the scanner.

With a 657, most likely the main board has failed. It is not uncommon at all, That is a general problem with that model.
What you can try is, looking from the front of the machine, the main board is located on the back right side. removing 2 screws and releasing the levers will allow you to slide the processor board out of the machine. You can try just reseating,,,, removing and shoving the board back into the machine, and seeing if that helps.
Most likely, either the board has failed, or the memory battery had exceeded its life and the memory is not working.
Wish I had a more positive answer for you, but the 657 is getting older, and those lithium batteries are failing. I have to add though, that those processor boards, have failed pretty frequently over the years.
What you can do is go onto Google and look up "the parts drop" ,,, call them and ask for Britt, and see what he has as far as that producut is concerned. That machine is actually made byn Toshiba, you may be be able to find either a Xerox, or Toshiba repair dealer in your area that has that board and will fix it reasonably. If you find a Toshiba dealer other than a Xerox dealer. Tell them it is the same machine as a Toshiba E-120, they are exatly the same.

Do you have the receipt for the machine? You have a 1 year warranty from Xerox on that machine, Here is the copy and paste from the warranty information on the Xerox website.

Xerox warrants that the Phaser 3200MFP product and its Consumables, Routine Maintenance Items, and Options/Upgrades (related items) will be free from defects in materials and workmanship for the periods set out below:
