The top module has dirt stuck and bottom module is clean. Please clean the scan module with Isopropyl alcohol. For emergencies take a drop of cologne on a piece of cloth and wipe the area that is dirty.

First check if the front side (i.e top) scans properly in the simplex mode. Try different contrast levels for better clarity. In the setting menu select appropriate contrast for both fron and back, then you should get good outputs. Even after all this if the front page gives dark output, may be the LEDs are not glowing due to lose contact. Try in color to check LEDs. S. Mohan, Chennai, India
SOURCE: 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.

It is dust on the glass, clean it thoroughly. You will find it at the same location for all drawings and may get faded for lower brightness!
