112 Chapter 9 General Troubleshooting
9.2 SCSI Communication Problems
Symptoms
• The following message is displayed saying that there is a
communication problem: No communication with scanner. Turn
scanner ON and check SCSI connections.
• The scanner does not appear in the SCSI chain in the SCSI
Information panel.
Suggestions
• Switch the scanner OFF, then ON. After 30 seconds (in EverSmart
Pro II and EverSmart Supreme, approximately after 15 seconds),
verify that the Status LED is a constant green.
• If the Status LED blinks green for more than 30 seconds, or is red,
call your service center. (In EverSmart Pro II and EverSmart
Supreme, if the Status LED remains red, call your service center.)
• Check that all cables are correctly connected, and that the SCSI
chain is no longer than 6 meters.
• Make sure that a terminator is connected to the last device on the
SCSI chain. If the scanner is the last device, make sure that the
terminator switch on the scanner is set to on.
• Check that two devices have not been assigned the same ID
number.
• Activate the SCSI Information application. Check if the scanner
appears in the SCSI chain.
