Question about Office Equipment & Supplies
I have a Sharp AR-337 copier and it has this problem:
The scanner locks up at the time its copying, sometimes it makes two copies OK and sometimes it locks up three or five times continuously, and the copier does not register any error code.
I have checked the main charge and the TC corona and they are in good conditions.
I have checked the scanner completely to see if it has any problem, and when i move it manually it moves without a problem.
I also checked the scanner motor, the scanner driver PWB, the PCU PWB and all its connectors and harnesses. And everything is all right.
And i have changed the scanner completely from another copier i have and the problem persists.
If someone have had a problem like this, could you help me?
Do you know how to get into the simulation mode
Like Clear ,exposure mode, clear , interrupt, are you familar with the service manual procedures ?with Sharp, are you an independant dealer. ? into simulation mode and run the Scanner mode, make sure it run back and forth ok, lubricate the track, if it gets stuck it will produce and error or stop running.
Before i can help you I need to know your expretise.

Issue: Scanner moving slowly sometimes stopping intermittently
Cause: The SCSI port A was pinching the supply voltage for the scanner cable at the rear of the machine
replace broken or pinched wired reinstal the SCSI port
this may also cause the ICU and the flash to become corrupt, in this case replace the ICU and the flash card
Scanner stops during scan , sometime causing l3-00
Cause : Pinched wire harness from the scanner motor pwb at the PCU pwb ( tie wraps to tight )
Replace wire harness and secure it to other harness but not to tight or remove tie wraps and repair the wiring
