Question about Canon CanoScan 9950F Flatbed Scanner
Canoscan 990F is connected to G5 Mac running 10.4.11 OS. When try to scan, the software says that I need to unlock the scanner and detach the I/F cable and then reconnect. However, the scanner is unlocked. This same message appears with two different scanning software apps. All cable connections are there and power is on. The power light on the scanner is flashing. Any tips would be appreciated. Thank you
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!

Tips for a great answer:
Guide to installing Canon CanoScan LiDE 35, 50 and 60 on Mac OS X 10.8. Mountain Lion:
FIRST PART: DELETING OLD LiDE DRIVERS AND SOFTWARE
HD:/Library/Image Capture/Twain Data Sources
delete the CanoScan CanoScan XXXX.ds file
(Make note of any other files that may be in this folder. If other files are present, move them to the desktop for now. Then place them back after successfully using the scanner.)
delete the 'CanoScan XXXX' folder
delete the folders containing the name CanoScan, or starting with CNQL.
delete the CanoScan Toolbox Application
delete any items named "CanoScan Toolbox"
SECOND PART: MAKING YOUR SCANNER WORK
CanoScan LiDE 50 and LiDE 35 work both with the 35 driver:
CanoScan LiDE 60 driver:
VueScan 9.2 (or later) x32 for Mac OS X
Alternative to VueScan: CanoScan Toolbox. I prefer VueScan.
Try your luck with Version 4 or Version 5.
CanoScan Toolbox 4: cstbosx4934ej4.dmg
CanoScan Toolbox 5: cstbosx5014ej4.dmg
(Alternatively try and install CanoScan Toolbox 4 or 5)
