For all other parallel based scanners:

1. Click on Start
2. Click on Run
3. Type in system.ini then click on OK.
4. Scroll down until you found [ScannerParameters] in [ ] look for Port_ChipType=xx make sure and set it to 17, then look for Port_Mode=xx and make sure that it is set to zero (0).

If the settings are correct and you are hearing grinding then disconnect the scanner cable from the back of the computer. Disconnect the AC adapter from the wall. Then reboot the computer. When Windows boots back up reconnect the AC adapter first then the scanner cable. After that is done disconnect the AC adapter plug from the scanner only and not the wall then reconnect it. Check the connection again in the scanner utility.

If you have done all the above steps and still hear the noise then it is possible that you have a defective scanner. In this case please call to talk with a representative about a replacement.
