English57Chapter 6. Troubleshooting and FAQ6.1 Troubleshooting6.1.1 Why does the driver sometimes show the message “SCSI cardnot found”, and a few minutes later, it works properly?To prevent damaging the scanner due to unstable power supply or shortcondition, the fuse on the SCSI card could be open for a while. During thisperiod, the SCSI card does not function but after a few minutes, the fusetemperature cools down and the fuse recovers. You can solve this questionby turning the scanner power off and turn it back on for a few minutes.6.1.2 The scanner can not work and the screen shows “Scanner notfound” instead.Make sure that the SCSI cable is connected properly to your PC and yourscanner is turned on. Otherwise, turn on the scanner, then enter WindowsControl Panel and click Refresh in Device Manager tab of System.6.1.3 SCSI Connection GuidelineScanWit film scanner uses a SCSI interface to connect to your computerand other SCSI devices. Depending upon the configuration you use, therewill be certain guidelines to follow in order to ensure the proper function ofyour ScanWit film scanner and other devices:Single Device Configuration (you connect the ScanWit film scanner directlyto your computer, and there are no other SCSI devices inside yourcomputer or connected to the ScanWit film scanner):In this case, you need to connect a SCSI terminator to the SCSI OUTconnector 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 SCSIdevice must have a unique SCSI ID number to avoid conflict between eachother. The last device on the SCSI chain must be terminated.In this case, make sure that each device on the SCSI chain uses a differentSCSI ID number (refer to the documents that come with that device fordetails on how to check the SCSI ID number of other SCSI devices) toensure the proper function of your ScanWit film scanner and other SCSIdevices.
