This error indicates a hardware problem which is considered a "fatal and service error" which requires a repair service.
This error indicates the scanner unit pcb fault or logic assembly board failure.
There is nothing much we can try apart from trying to reset the printer.
This might work but most of the times it doesnt then you need to carry out the repair service.
Unplug the power cable from the printer and leave it off for an hour.
Before plugging it back to the power source
press and hold the power/on button for 60+ seconds then release the button.
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 $120-200, while you could buy a brand new printer. Check the purchase date if its under 1 year then you must go for the warranty service claim to have it repaired.
Let me know how the reset goes.
