Question about Kodak Digital Science 3520DP Path-Through Scanner
I'm trying to scan documents on a Kodak DS3500 scanner that is giving me a can't communicate error.(check the power, cables and card)
Also I'm looking for information on testing the circuit boards or other hardware inside the scanner.
Thanks in advance for your assistant
Are you using a Kofax SCSI card or an normal SCSI controller like Adaptec?
By using a normal SCSI controller, is there an ASPI driver problem after a WIN XP update? After an update check the ASPI dlls in \sytem32. They should be version 4.71 or higher.
Check the SCSI connector pins and the terminator.
If available change the cable.
Is the green lamp (Ready) on or is the red lamp (Error) on?
- green lamp on:
the internal self test is ok, but the internal SCSI interface may possibly faulty.
- red lamp on:
the internal selftest detect an error.
It's possible that the DC/DC power board, the CPU board or the power supply inside the scanner is defective.
After reassembling the front side camera you will see at the bottom a PCA board with some LEDs whitch indicate by red light the different voltages when power is on. You find the different voltages printed at the PCA close to the LEDs.
In case on or more LEDs don't shine the according DC/DC transformer on the PCA is defective.
Futher you see LEDs at the camera PCAs. They should be on too.
In case the CPU board has an defect you must have an special Kodak activation tool to unlock an new or used CPU board after exchange.
