When attempting to use this scanner with paperport 11, the scanner light flashes and I get the message scanner cover is open -4429. Back cover of scanner was removed due to paper jams. Scanner previously worked without the back cover and now it does nothing.
SOURCE: Makes a loud clicking noise and reads scanner error.
I had this exact problem. This printer was given to me, so I didn't have the instructions. I'm pretty sure I damaged it when I tried to open it to change the ink. I didn't realize there was a lever. After I got it open, I had trouble closing it, but eventually I got it to sit down flat. It was after this that the scanning function ceased to work as described by others.
I searched online to find a solution, but was hesitant to buy a repair manual. I read about someone else who took the unit apart. His experience was really a help as he knew just what part to take off. You need to remove the gray panel on the right side of the unit (as you are facing the front). This is the side with the USB port.
There are only three screws to remove. I used a flat head screw driver to gently pry the pieces apart. There are two places it snaps together on the bottom of the unit. I was able to get it apart without damaging anything. Once it's open, you will be able to see there are a few ribbons that connect the top of the unit to the circuit board in the base. For me, two of these had come loose. I simply slid them back in the slots where they seemed to belong and put the thing back together.
It was easier than I imagined and it worked! Good luck.
SOURCE: Paper Jam
I have just had the same problem on one of these Canon MF4150 machines.
The manufactures warranty on our machine had expired just one week before this happened so I had to fix this myself.
The problem we had (which is very likely to be the same cause as yours) is when we removed some torn jammed paper, it had somehow pulled off a spring from inside the machine. The spring was linked to the paper jam sensor.
It does involve a LOT of work to fix it, and unless you are very 'techy' it may be quite a difficult task to do this for the 'average' person.
I had to completely disassemble the machine:
Take off the front first (lift up the cover and there is 2 screws at the front and 2 clips on the bottom of the machine)
Then remove the 2sides and finally the top (screws should be easy to see, to get the sides off, un-clip along the front edges and gently move them outwards and slide them backwards to release the clips on the back) being careful with the wires going to the scanner part).
Then look for the fuser unit which is near the top at the back, there is a black rounded cover over the fuser. To remove the cover, look for 2 small clips one at each side and unclip the cover and gently lift upwards.
Under the cover on the left side you will see a small plastic rod which goes from the left side to a small tab in the middle, if you look about half way along that rod you should see a tiny spring, make sure this is clipped on properly and that you are able to rotate the rod and it should spring back to the proper position when you let go.
Once this is done, put it all back together again and it should work fine.
I'm sure a lot of other people probably have this same problem too so I hope this helps someone.

Have you noticed any quality difference in the scans? Sounds like it is set to scan at a higher resolution which will take longer.
SOURCE: had paper jam. removed paper,
I have the Canon Pixma iP4000R printer. I had an error code of 6A00 and my power light was blinking/flashing green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange-green-orange (12 oranges).
I tried the “waste ink counter reset reset” procedure: Power on while holding the stop/reset button and pushing the service button twice, then pushing the stop/rest button 4 times to clear the error, but that didn’t work.
My ink cartridge carrier wasn't moving-staying in the center. I thought I had a paper jam.
I looked at a few blogs about my error on other Canon Pixma models and they kept talking about “sponges”.
The following is what I discovered that cleared my error and now my printer is back to printing!
The “sponges” are 2 hard pieces of absorbing plastic or something of the like. I was looking for a softer material like the long thin gray foam strip material in my printer. The 2 "sponges" on my Pixma iP4000R were next to each other-one was rectangular and one was square-like. Originally they were white but the ink made them black/navy.
The "sponges" are located on the right under where the ink cartridge carrier "rests".
I didn't see the sponges at first, as there was a white backwards “L” shaped plastic piece that had a spring attached to it(purge unit). The “L” shaped piece was moved forward out of its place. I used my pen tip and pushed that piece back and found that the rectangular "sponge" had popped out of its place.
I used a pen tip popped both “sponges” out and rinsed them with water and voila they were once again white. I think the rectangular one had so much ink on it it popped itself out of place.
My error is gone and I can print again!
