    "No device found" on my Canon DR-2080C.   On a semi-annual basis, the device just disappears and all of the standard appraoches do not work.   new usb cable.   uninstalling and reinstalling drivers.   New USB hub.   Uninstalling all canon software and reinstalling it.   Shutting off computer and turning it on.   I wonder if it is the hardware USB 2.0 firewire connection in the scanner itself that goes bad.  because the last time I just swapped scanners and the new one worked fine.   but now this is the swapped scanner that stopped.   I ahve spent hours on this frigging problem.   Wasting my time.   I should just buy another one on ebay!

Ive had this problem as well, and usually restarting the computer fixes the issue. im guessing that you have already tried that, but just incase ill suggest it. You can also go into device manager and remove it, and then use the software disk, reinstall.

Unknown error. Canon DR-2050C/2080C Driver version 2.2.10412.07001 (-4523)


I have many years repairing Canon scanners so I hope my suggestion helps you out.

In my experience with the problem your having I have found that the bios needs to be flashed on the particular model scanner you have. You will need to contact your local canon dealer to have this done because they have diagnostic software to do this with. Also they can run the diagnostic software to tell if there are any other issues that need to be addressed on your scanner while they are there.

I hope this helps you out if not let me know.

Installed driver twice for Canon DR-2050c. Still


Pls run checkdisc/scandisk on your Comp. Your OS may be corrupted. Just to verify try scanning by connecting to a formatted newly loaded OS Computer.

My Canon DR-2050C keeps jamming when I try to scan more than 1 page???


I finally solved my problem. Now it works like new.

Cause:

- The spring that returns the next sheet detector (small black plastic rocker arm between the two rollers on the back side) came off. So the scanner cannot detect transition from one page to the next. This spring is located inside the device and you cannot fix it from the outside.
- You know if you have this problem if you don't hear a "click" sound after each page is scanned. Without the spring attached the rocker will not return on every page. When it doesn't return the scanner think it is still on the first page and will not scan the next page. The "click" after each page is NORMAL. Without the click is the first sign your spring came off.

Solution (Only recommended for people handy with hardware and the unit is no longer under warranty)

1. Turn off power and unplug the device.
2. Pop off the plastic cover to the back of the scanner
3. Remove the screws that holds the plastic cover to the back.
4. Remove the screw by pushing on the retainer clips. DO NOT loosen any gears or motors.
5. Locate the rocker arm and re-connect the (very small) spring

6. Warning - if the LED light pipe falls out be careful how you put it back. This is a transparent widget at the top to route a LED light to the top of the device to indicate the power on status.

Sorry I didn't take pictures. If this sounds too complicated, send it to Canon for repair. Took me about a day to figure out exactly what was wrong and how to disassemble the scanner to fix it.

Good luck.

DR-2050C Scanner all sheets feed thru only one scans


Do you get an error message after the first scanned image? If not, check your software settings to see if you have the option of single page /multipage scanning. Some software lets the customer choose a single page scan when the SCAN button is pressed.

Check the "Feed Select Lever" to make sure it is in mutifeed position. If not, it will grab all of the docs at once.
