• The scanner home position sensor (PS100) does not go
from HIGH to LOW when the scanner motor (M4) is energized

THANK'S

Sound like the scanner is the issue, is it under warranty? OR the Scanner may be locked, check for the scanner release device unlock it,.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

F62 error is a problem with the lamp gain on the rear page camera .
Usually removing the camera & cleaning the optics will sort it out .
The scanner will need a good service & shading adjustment as well .
Only attempt this work if you are familiar with CCD Devices & care, as damage through mistakes can be very expensive .

Was there any resolution to this problem?

The shading alignment is a software alignment fix and unplugging the unit will solve this problem. You will have to do a software shading alignment to correct your problem. I've lost my notes while moving and I can't give you the procedure for doing this.I hope this helps a little.

The issue at hand here is a sensor error. Cut the power to the machine for at least five seconds. Then reboot the scanner and the sensors should reboot. This solved the problem for us. Good luck to you.
