Looks like tthe scanner is broken, could be stuck perhaps?

fairly typical of the 33X0 model mfps. The scanner has lost its calibration. Try a factory reset - warning - you will lose custom settings (speeddials, header/fax number etc)
To do a factory reset, power off machine, hold down menu/enter and *, power on machine while holding buttons down and wait for "permanent storage init" to display, then let go of the buttons. After a couple minutes it should be back to a ready state.
