Replace the switch. A trick can be done here. Unplug it then spray the switch (Soaked) with warm distilled water with mild soap. then let it dry using a Hair Dryer. Then test!

Is the lid for the canoscan 9950F detachable? I need to scan large drawings and keep the lid in serial with the scanner. Is this possible?

Yes, you can detach the lid very easily. Open the lid and when in vertical position, just pull upwards. The lid is held by two metal rods, which will come out when you pull up the lid.

How to pick off glass of canoscan 9950F I want to clean the dirt on the lamp and the inner side of glass please HELP

Unplug power source.

Disconnect cable connecting the lid to the base.

Remove the lid by pulling straight up.

Using a phillips head screwdriver, remove the two screws that can now be seen at the bottom of the slots into which the lid hinges were inserted.

Starting near the hinge slots, pry the black plastic frame up and away from the gray plastic body.

Slide the glass panel and its gray plastic frame towards the back of the scanner and lift off.


Scanner Glass Smashed

More than likely yes, unless you like to mod things than perhaps you could replace it with plexi glass. Could not promise it wouldn't even work after that but would also take time and know how.

Hi My Canoscan 9950f flatbed scanner glass has been smashed........ Is that the end of the road for it?? Or can it be fixed?

I had the same problem, shipping the scanner from Olympia, WA, to Austin, TX, the main glass broke (the sheet of glass you see when you open the scanner lid when it is set to scan an opaque object like an 8x10). I ordered a replacement part from the Canon parts center in New Jersey (732-521-7230) and at the time she told me there were only two left in the country, so you might be able to get the last one.

To replace it you just need to lift off the scanner cover, remove one scree in the bottom of each of the two wells the cover posts fit into, and lift the dark plastic part on the back of the scanner up (I think there are a couple of plastic snaps on the back side but they are not easily broken. Just pull up uniformly on both sides. Then you can remove the broken glass and put the new sheet in (align the plastic guides on the new sheet just like the ones on the old one were aligned).

Unfortunately, my scanner still doesn't work -- so I may have to give up on it. It seems stuck on a fairly well known failure code (2,178,0) when I start to scan and Canon customer support says there are no authorized service centers for the 9950F (I wonder if all their scanners are not repairable?).

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!

Install CanoScan 9950F Driver

I found the answer to the 9950F VISTA driver - I went onto Canon's site and downloaded the VISTA driver - AND - the toolbox. Then a reboot and this time Vista recognised the 9950F.

Canoscan 9950f red line on scan

Try running a calibration. This is done thorugh ScanGear in Advanced mode. Once in Advanced Mode, in the Image Settings section there should be an option for Calibration (you may have to scroll down in this section to see it). After running the calibration, try performing a preview scan with nothing on the scanner glass. If the red line shows up on the preview now, then most likely the scanner needs to be serviced.
