FUJI Frontier Sp500 problem


Recommended Posts

Hi all

I am having trouble with my newly bought sp500. I am using vmware and FE software. It was running fine before and I can scanned few images like normal.

Today when I turned on the scanner. I noticed that the led light in front of the scanner unit (power and state) they are not lighted as normal. Scanner is on I can tell by the fan make noise. I checked behind all fans were running normal. Problem is the scanner wont start also the scanner is not recognized by the software. Hence I cant scan or evem calibrate as its not recognized now.

Inside the scanner i can see the light source lit up reg green blue light. And also i saw some light by peeking through the scanner grill. 


What may be the problem with this? Mainboard or power supply?


Thank you for any inputs

Missing voltage. Probably 5v. So... Damage mainboard or power supply.

Hello, can you tell me according to the Wiring Diagrams where I should test the voltages with the multimeter?

When power supply is powered and pressed power button can check voltages on connectors PS2, PS3, PS4, PS5, PS6 and PS8.

Grateful!  As soon as I can I will run the tests.
