This link will take you to the canon Down load drivers center.

Go to their official webpage, and try to find software... or just download this Driver Update Software for XP Vista 7 8 and make the update. I hope I have helped. Have a nice day

Clean the glass thoroughly with a damp cloth.

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.

after scanning front and back are black

Have you installed device driver? It is just not enough if you install scanning software. Also trya different USB port o a different USB cable.

i want the driver for canon dr-2050c

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.

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.
