SCSI Problems and Solutions

Problem:
I get one of the following error messages:
Windows system: "Scanner access fail" error message when performing scanner test.
Macintosh system: "Scanner not found or ready" error message when accessing scanner.
Solution:
If you get one of the messages above when you run the scanner test or when you try to access the scanner,
follow the instructions below:
1. Make sure the ready light on front of the scanner is solid and not blinking.
2. If you are using a PC computer, make sure your SCSI card is showing up properly in the Device
Manager.
3. If you are using PC computer, make sure the scanner shows up in the Device Manager. The scanner
will show under the heading Umax Series Scanners in Windows 98 and Imaging Device under
Windows 95.
If the scanner appears under Scanners in the Windows Device manager, search through the UMAX
Smart Site FAQs (from the UMAX web site http://www.umax.com) for Adaptec. Follow those
instructions.
4. Make sure that the SCSI ID for the scanner does not conflict with any other SCSI devices connected to
your system. The default SCSI ID setting for the scanner is 5. You may find that other SCSI devices
(such as zip drives) also use SCSI ID 5.
If you find more than one of your SCSI devices is set to the same SCSI ID, you will need to change the
SCSI ID of one of the devices. Refer to your computer or SCSI adapter card documentation for
instructions about changing the SCSI ID.
5. The SCSI cables may not be connected properly, and/or the SCSI terminator may not be required.
There are four possible connection configurations:
•
Cable connected to SCSI connector 1, no terminator
•
Cable connected to SCSI connector 1, with terminator on SCSI connector 2
•
Cable connected to SCSI connector 1, SCSI cable chained to another SCSI device on SCSI
connector 2
•
Cable connected to SCSI connector 2, no terminator
If you are having problems with the scanner, try connecting the scanner with the terminator on. If that
does not correct things, try removing the terminator. You can also try flipping the cable end for end
and reconnecting the cable with or without the terminator. Make sure you cycle the power to the
scanner by unplugging and plugging it in. Be sure to reboot between trying different cable positions.
