Re: Xerox 7545 - Scanner Fault - Fault Code 362.476.00

Sorry, it's a bad one.

Something is broken or un-hooked in the scanner and will require service.

This is what i can dig up: Short version is the scanner isn't moving because of a blockage, a breakage or something came unplugged.

Problem:Scanner fault 362-476. Scanner moves to the right about 1 inch and at 
boot up and doesn't move back to the left like normally operation. Lamp doesn't 
illuminate either. Component control doesn't work for any scanner components. 
Cause:Scanner home sensor 
always reading home position. Not changing high\low states when scanner assy 
moves to the right. This causes the printer to trigger the fault. 

Replace the Carriage home sensor 

And

Problem:The plastic spring hook on the bottom of the plastic scanner pan is broken.
The belt tensioner inside the scanner needs to be held by the spring. . Therefore the 
belt becomes loose and gives 362-476 fault codes.

 And

Problem:The scanner does not move or light up when closing the dadf.Cause:Bad 
connection on SIP or scanner pwb.
Reconnect all scanner pwb plugs and SIP plugs, suspect the small ribbon 
on scanner pwb.
