Communication
The communication incidences between the HP Scanjet Scanner and your computer can be easily solved by checking the following sections:
Cables
Power cable

Check that the power cable is securely connected between the scanner and a working electrical outlet or surge protector.

If the power cable is connected to a surge protector, make sure the surge protector is plugged into an outlet and turned on. Otherwise, try connecting the scanner power cable directly to the outlet.
USB cable



Make sure the USB cord delivered with the scanner is being used, or use a certified cord identified by one of these logos.

Check that the USB cable is securely connected between the scanner and the computer.

The USB icon on the USB cord will face up when the cord is properly connected to the scanning device.
Parallel cable

Please use the parallel cable supplied with the scanner or a high-quality IEEE1284 Compliant parallel cord.

Verify that the parallel cable pins are not bent or broken.
SCSI cable

Please use the SCSI cable supplied with the scanner. Another SCSI cable might not be compatible with the scanner.

Verify that the SCSI cable pins are not bent or broken.
Software
Some error messages occur due to the operating system and could display with any HP Scanjet scanner while other errors are specific to the software being installed. Make sure to check all sections for the scanner, software in use and the operating system.
