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. Service for these is not practical either, as repairs on your own would be $200-250, while you could buy a brand new machine for not much more. As this is a 2010 model, it is already past its 5 year service life and wouldn't be considered worth fixing, thoguh you could certainly keep it as-is, if it will let you print still, and buy a standalone scanner instead.
Let me know how the reset goes, and I'll help service options or replacement recommendations at that point if needed.
