Yes, thought that would be the case but was chasing straws anyway as it is a good slimline reliable little unit that has given me no trouble over all those years. Hopefully the new one will be just as reliable. Thanks again and knew that is what I would have heard back. Cheers!

My guess is that changing the method of connection on the fly is not supported by the drivers, but that an uninstallation then a fresh installation reflecting the current physical hookup should get it going again. First, uninstall any Canon software currently on the computer, then physically disconnect the scanner. Restart the computer. Next, check the documentation to make sure the CORRECT cable is being used. IIRC, those printer-bypass scanners did not use standard IEEE1284 cables when bypassing a printer, but did use a standard cable when directly connected to the parallel port. Also check to see if you need to enable/disable any specific settings for the parallel port, either in the BIOS (ie, Bi-directional, EPP ECP) or within XP (ie, IRQ related). After looking into all that and adjusting as required, download the current drivers and then do the instalaltion as if this was the first time it was being installed. Post back to let us know if it worked for you!

Thank you for your time and research and will follow it now. Thanks again.

We did everything as you suggested and then realised that we would also need to purchase a power supply 9.5V. Previously the scanner received its power via the printer it was attached to and of course once it was no longer attached would obviously need its own power. We are feeling rather foolish but still think we would have required the other information you gave us. Will let you know if the power source is all we needed but won't be able to get it for a few days. Will be in touch with the info but thank you very much.

It is not often I make a stupid call to annoyances but found that when my friend separated her scanner from the computer etc, the power cord also discarded itself to the floor. With so many cables etc with computers we did not see this and have been working on the problem for a couple of weekends together. Anyway apparently it always had its own power source but we assumed it was coming from the computer - NO. It was on the floor. Anyway at least with your help which hasn't gone to waste we now have the new updated drivers and all is working really really well, even by changing the BIOS settings which we still may have had too. So sorry to bother you but appreciated you coming to our rescue and at least it is now a happy ending even though we are red faced. Do think the BIOS was needing to be changed but you would know that better than us. Thanks again and just know your information has taught us something anyway.
