This code is not listed in the 264 manual but it is in the 283 manual as a checksum error. Upgrading firmware would be a very good start. Here are a couple of other choices from the MXM283 troubleshooting guide.

Good luck.

You can not enter simulation mode when you are in the fax screen, instead your code is put in like a phone number. I was able to enter simulation by choosing copy directly after the machine booting, or by hitting the simulation keys over and over from the sprite screen until it loaded right into sim missing the fax mode.
