Chapter 6. Troubleshooting and FAQ
6.1 Troubleshooting
6.1.1Why does the driver sometimes show the message “SCSI card not found”, and a few minutes later, it works properly?
To prevent damaging the scanner due to unstable power supply or short condition, the fuse on the SCSI card could be open for a while. During this period, the SCSI card does not function but after a few minutes, the fuse temperature cools down and the fuse recovers. You can solve this question by turning the scanner power off and turn it back on for a few minutes.
6.1.2The scanner can not work and the screen shows “Scanner not found” instead.
Make sure that the SCSI cable is connected properly to your PC and your scanner is turned on. Otherwise, turn on the scanner, then enter Windows
Control Panel and click Refresh in Device Manager tab of System.
6.1.3SCSI Connection Guideline
ScanWit film scanner uses a SCSI interface to connect to your computer and other SCSI devices. Depending upon the configuration you use, there will be certain guidelines to follow in order to ensure the proper function of your ScanWit film scanner and other devices:
Single Device Configuration (you connect the ScanWit film scanner directly to your computer, and there are no other SCSI devices inside your computer or connected to the ScanWit film scanner):
In this case, you need to connect a SCSI terminator to the SCSI OUT connector on your ScanWit film scanner.
Multiple Device Configuration (in addition to the ScanWit film scanner, there are other SCSI devices on the SCSI chain):
A SCSI chain allows up to 7 SCSI devices to be connected, and each SCSI device must have a unique SCSI ID number to avoid conflict between each other. The last device on the SCSI chain must be terminated.
In this case, make sure that each device on the SCSI chain uses a different SCSI ID number (refer to the documents that come with that device for details on how to check the SCSI ID number of other SCSI devices) to ensure the proper function of your ScanWit film scanner and other SCSI devices.
