For the 9636T, 9636P+, and 12000T:

13. You should now have Chipset=17, PortMode=0 and IOBase =378. Close out of the registry Editor and reboot your computer.

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 still getting the message 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 that doesn't work then unplug the scanner cable from the scanner and the printer cable (if you have one) from the scanner and plug them together. Open up your word processor, type a brief sentence, then print it to see if your printer works. If the printer performs then you have a bad scanner which needs to be replaced.

If you have any further questions or problems, please feel free to contact our offices directly at .
