Scans says it needs to be unlocked but already is.

Seems like lots of people have the same problem. So far I've seen no solution. I have a canoscan LIDE 20

Would appreciate some help.

To be clear, under the scanner, you have already peeled the seal stickers off, and slide the unlock slider from the lock icon to the unlock icon.

If your switch is firmly in the "unlocked" position and still get the error, then plug your USB cable into another port on your computer and restart. Make sure you are NOT using the USB ports on the FRONT of your computer and DO NOT use a USB hub. If the error continues, then there is a malfunction in the scanner and must be replaced.

Pages come out crooked and upside down on their own - not operator error! Why does this happen and can it be fixed?


I had the same problem scanning to PDFs with the CanoScan Toolbox until I went to the File Settings dialog, and unchecked the option "Detect the Orientation of Text Documents and Rotate images". Now it seems to work more predictably (no more scans that have been rotated for no apparent reason).

I am unhappy with the light level while scanning slides.


I haven't solved the light problem, but I have found a pretty good program that allows me to enhance my scanned slides-pics into nearly slide-projector quality pics: XnView. I have found that it is best to not try to use the enhance program in PhotoStudio 5.5 (the driver-program for the Canonscan 4400F).

Canoscan 9950F won't scan, says scanner locked, but it isn't


I was surprised by the same problem this morning. First time I've had a problem with in years. Checked the lock... it was already unlocked. I solved the problem by unhooking the USB cable from the hub, restarting my Mac (seems to be the key), replugging the cable and restarting the scanner. Worked like a charm. Hope it works for you!

Make sure the scanner is unlocked. Lock switch is either on the bottom, or under the scanner lid near the hinges.

Not scanning


You have tried everything possible!. Try and reinstall the OS. If some dll files are corrupted, this will resolve it. You may have to reinstall all other software!

CanoScan N1220U Scanner properly installed but not workin


This doesn't do "one button" scans, but I just downloaded "VueScan" for my 10.5.4 Intel Mac and the demo is working great with my Canoscan N1220U.
