Re: Canon Gp335 scanner problem!

It sounds to me like the exposure lamp has not reached the proper intensity. Check for error codes stored: E220, E301, E803 and protection jam 0400.

Also check that lamp heater has not slipped around, covering the lamp intensity sensor opening.
Also check exposure lamp for blackened ends or arcing contacts.

Also check the home position sensor, clean it out, they fill up with dust etc & can cause odd faults with no error code.

-The No. 1/No. 2 mirror mount is driven by the scanner motor (M3). The scanner motor is a stepping motor, and is controlled by the image processor PCB.
The position of the No. 1 mirror mount is detected by the scanner home position sensor (PS1).

The scanner fails to move forward/in reverse.
-Is the scanner drive cable routed correctly?
-Is the scanner rail free of dirt, and does the scanner move smoothly?
-Is the wiring/connection from the connector J116 on the DC controller PCB to the scanner motor through the relay connector
J28 normal ?
Replace the scanner motor or DCPCB


Scanner home position sensor=PS1

DC PCB=J112BPS1-.JPG

E202 (The scanner home position is not detected.)
Is 5 VDC present at J112-B5 on the DC controller PCB when the scanner is at PS1?
