Unfortunately this error indicates a hardware problem which is considered a "fatal error" and will almost certainly require service.
This specific error pertains to a scanner pcb fault and/or logic board failure.
The only thing you can try in this case is to reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release
If still on change, it confirms an internal fault, which requires service.
As this is a 2010 model printer, it is well past its 3 year service life, so this type of failure is not surprising. While it can be fixed, it is not worthwhile to do so. You would have to, at a minimum, replace the scan head/pcb, which costs about $150; if the logic board is bad you’re looking at $200-250. For $80-100 you can replace the entire machine with a brand new model, with current technology and a fresh warranty, which makes more sense than buying the new part for an older printer.
