■The Scanner Is Not Recognized (Connecting via USB)
If the scanner’s USB connection is not recognized, first confirm the following:
✔Are the scanner and PC connected correctly using the proper cable?
✔Is the scanner’s power switch turned ON?
If this does not solve the problem, consider the following possible causes:
Cause | The scanner does not support your USB |
| interface. |
Solution | This product is not guaranteed to operate with |
| all types of USB interfaces. Contact your local |
| authorized Canon dealer or service |
| representative for more information. |

|
Cause | The scanner does not support the USB |
| cable. |

| scanner. |
Solution | Remove the USB hub. |
|
|
Cause | The SCSI terminator is not set to ON. |
Solution | When using a USB connection, proper |
| scanning may not be possible if the SCSI |

■The Scanner Is Not Recognized (Connecting via SCSI)
If the scanner’s SCSI connection is not recognized, first confirm the following:
✔Are the scanner and PC connected correctly using the proper cable?
✔Is the scanner’s power switch turned ON?
✔Is the SCSI card in the PC operating properly?
✔Was the PC turned ON before the scanner?
IMPORTANT
When using the SCSI connection, if the scanner is turned ON after the PC, it may not be properly recognized by the PC.
If this does not solve the problem, consider the following possible causes:
Cause | The SCSI card is not compatible with the |
| scanner. |
Solution | |
|
|
Cause | The scanner’s SCSI ID is identical to the |
| SCSI ID of another device. |
Solution | Check the SCSI IDs of all SCSI devices |
| connected to the system and set a unique SCSI |
| ID for the scanner. |
|
|
Cause | The terminator is not set correctly. |
Solution | When another SCSI device is connected |
| between the scanner and the PC, that device’s |
| terminator must be disabled (set to OFF). |
|
|
Cause | There is a problem with another SCSI |
| device that is connected in the daisy |
| chain. |
Solution | Do not use the daisy chain connection |
| configuration. |
