problems with CanoScan 9900F

[kurtdebrouwer]

I bought a brandnew CanoScan 9900F (on Ebay though...) and seem to have a serious problem. I was testing the scanner and trying to perform a calibration. After I gave this command my computer froze and I was forced to stop this task pushing CTR+ALT+DEL. That was the start of some major problems with my scanner. Since then I get all the time the following error message : "Release the lock switch, detach the I/F cable and reconnect. Scanner driver will be closed". First of all the lock switch was not locked, secondly even if I recheck everyting the same error message returns again and again. Could it be the scanner is internally blocked ?? Does anyone recognize this ? Is anyone able to help me out of this akward situation ? I would be so thankful !!!!!

Have you tried the usual trouble shooting - unplug the scanner from the PC and from the power outlet, reboot the PCm, power up the scanner and re-plug the USB cable (check the power button on the front of the scanner). If you still have problems, uninstall the Canon scanner software and start from scratch.

Hi,

I bought a canoscan 9950 (new) and had similar issues. I recall at the time it was due to the film loading frames I was using being incorrect.

Make sure that both the source and film size reflects that of the film type you are trying to scan.

Cheers
