Xerox 7545 - Scanner Fault - Fault Code 362.476.00

[Joe Arseneau]

I honestly don't know, I am far from a hardware guy, I just have a lot of resources for looking up information. Trouble with that is I don't always understand it.

Hello Joe,

I really appreciate your help with this.  I think we're getting warmer.

Do you know what Stepper Home Error means?  What and where exactly is the Image Input Terminal Printed Wiring Board?

Thank you!!

Hello Joe,

Thanks so much for your reply.  

For the possible reasons for error--

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 

The scanner does not move and the lamp is constantly on.  So even when I close the hood, when I look between the hood and glass, you can see the light is on.

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.

I checked the all springs and they look to be securely on and functioning properly.

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.

The scanner light is on and does not turn off, so it has the opposite problem.

With this information, is there any solutions that you think may work?  Thank you!!

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.

Hello,

We have a Xerox 7545 and this problem has been driving me absolutely nuts.  The image attached shows the Scanner Fault message.  The error code is 362.476.00.  The machine can print, but no copying or scanning.  I followed the directions, powering off and then back on, but that doesn't work.  I don't know what to do.

I really hope someone can help us with this problem.  

Thank you!!
