Question about Canon CanoScan 8400F Flatbed Scanner

Canoscan Won't Scan

I moved the scanner from one place on my desk to another, and unplugged the usb cable in the process. The next time I went to use it it wouldn't scan. I didn't do anything rough with it and I've restarted my mac several times since i re-plugged in the usb cable. When I try to preview it says that either i left in the protective sheet or the lamp is too cold ... i live in san francisco and i didn't put the protective sheet in... any ideas?

    Having the same issue after scanning film successfully, but when setting it to scan a photo again, I get the same message, and it will not scan. Tried turning off/on, making sure the lid is on correctly, etc.

    I also have this problem and get that same error message. Reinstalling the drivers did not work for me either.

I have the same problem with my 8400f. I moved it across the room and am getting the same error message. I have reinstalled the driver several times. No go. I hooked the scanner up to a Mac that had never had the driver installed before and am getting the same message. I used the scanner successfully a month or so ago. Now nothing.

Make sure the USB cable is properly connected at both ends. Close the Canoscan software and then reopen it and try again.

Errow msg. "release lock switch and detatch the i/f cable" still will not scan.

There is a switch on the underside on the scanner. This is the lock switch. Flipping it should solve your problem.

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!

Trouble shooting

The "car sound" could be an indication that the scanner is locked. Check the lock switch on the bottom of the scanner. Move the switch back and forth a few times and then leave it in the locked position. Another possibility is that you are scanning heavy items such as books. If too much weight is placed on the scanner glass, then pressure could be enough to prevent the scanning element from moving as it should.

The code 201 sometimes can indicate a power issue...meaning the scanner is not getting enough power. Try connecting the usb cable to a different port on the computer (preferrably directly to the computer and not through a USB hub).

Canoscan 4200f Problem with Vista 32 bit

I got mine working after experiencing the same problem.

I had mine hooked up to a USB hub, after I hooked it directly to the USB ports in the back of my computer, everything just worked fine.

Weird that it worked on the USB hub on XP and not vista though.

My pc will not recognize my scanner

uninstall again. download updated drivers from website then install the software again. make sure the usb cable is unplugged. install software frist then plug in usb cable make sure it is powered on.
