Question about Canon PIXMA MP830 All-In-One InkJet Printer
I place a stack of originals in the ADF and press Copy or Scan. There is a sound of a motor running, a pause, and then the motor running again. The paper is supposed to feed during this second phase but does not always feed. For me, it would fail to feed, ask me to clear the ADF, and press "OK" a random number of times and then suddenly it would work once or twice and then fail again.
I am a retired engineer and my feeling was that if could work properly even once, then it should work every time. The problem must be something intermittant relating to temperature, humidity, age, etc. It must be easily fixed.
The rear of the ADF has a silver-grey plastic piece which covers the feed motor and gears. You gain access by removing the one Phillips screw, opening the lid, and carefully prying the retaining lip at the right end of the silver-grey piece until it lifts up. The piece is then removed by sliding the retaining "leg" free at the right end of the piece.
Inside, you will see some white plastic gears. One gear is mounted on a floating idler arm. This gear controls feed and reject (I think). The feeder fails when this idler does not flip freely from one positon to the other. Carefully place a SMALL amount of very light (low viscosity) oil on the ider arm and verify that if easily moves back and forth.
Test the unit before replacing the silver gray cover piece.
That fixed it for me.

I scanned some magazine articles and one page broke apart. A piece of the page was lodged inside the rollers and I could not see it. The scanner gave me an error that there was a paper jam inside the ADF. Apparently there is a space just behind the rollers that a small piece of paper can lodge in. It is literally an empty compartment behind the rollers that you cannot possibly see into. Below are instructions on how to remove this seemingly unaccessible jam.
I first removed the two screws at the back of the ADF under the lift-up lid that connect the side/top panels. The side plastic/top pieces rotate up and can be removed. Four screws hold the ADF device in the lift-up top. I removed these 4 screws. With the power disconnected, I unplugged a wire assembly and unscrewed an electrical wire. This allowed me to remove the entire ADF assembly from the lid.
At the end with the rollers, there is a metal plate with 6 screws. I removed all six screws. Beneath this metal plate are two springs, three rollers and a metal bar set in place into slots. I removed these. I then removed the plastic inside part. You can rotate it slightly and then twist it off.
Now you can look directly into the space hidden behind the rollers. I used a paperclip to remove the piece of magazine. I then re-connected everything in reverse. It worked first time.

Addition to Solution #5 bart_evans: In my case the idler didn't function properly as well, but oiling the idler didn't solve the problem. When trying to push the idler upwards with my finger, I felt that some cogwheels had to snap into place. When I put oil on a cogwheel that was deeper in the printer that problem was solved. :-) Thanks Bart

Finally fixed the ADF!! This was a solution for my printer - maybe some of you have the same problem. Canon support wanted me to send in my MP830 for repair (which by the way, costs more than a new printer), so I decided to try and fix it myself-since it wasn't working anyway, I couldn't do much harm. There is a small hairpin-like wire that disconnected from one of the gears so the ADF wasn't pulling the paper. I took the ADF apart-very carefully so I wouldn't lose the place of any of the small gears. Reconnected the wire, and wha-la, the ADF is now working. This was not easy by any means, so I wouldn't recommend to start taking your ADF apart unless you have complete faith in yourself to get it back together.

I just got that message and was a little disheartened by the helpless feedback. Check all areas of the adf feed area. I found a band aid stuck in the underside of the cover when I lifted it up. Pulled it out and the message went away.
As far as the band aid, my roomate is a moron. I don't know what she did and I don't want to know what she did.

I just got that message while I turned on the printer and lifted the top portion to change the ink. The "door is open" message came on so I put the door back down and then shortly got the error message. Pressed ok and the message won't go away.

After a call to Canon resulted in advice to spend money at an authorized repair dealer or get a discount on another Canon printer (!!), the best solution may be to gather all users with same problem and take legal action.

Solution to remove paper from ADF was to remove inner ADF mechanics from frame:
Over all 10 screws but pretty simple without disassambling the gears.
From bottom one can turn some of the gears manually to romove the paper.

Canon Pixma MX330, ADF error, Code : 2,103,0
Here's what I found. There were no stuck gears or pieces of plastic caught anywhere.
The ****** can still feed paper, except for (consistently) the last page -->error/stuck.
1) In order to CLEAR THE ERROR you need to do two things
a) & b):
a) Press OK, WITH THE HOOD OPEN, with a piece of paper loaded in the ADF, being careful to grab the paper manually as it comes out of the bottom of the hood.
b) Windex the strip of glass surface which sits under the ADF next to the platen. This needs to be done with attention to minute detail, and a bright LED flashlight; since ink smudges off of documents and collects on the glass with alarming frequency. The machine may think these smudges are caught/jammed paper.
2) In order to SCAN a stack of paper, add one blank sheet to the bottom of your document. This page will be the one that
fails to clear the ADF, generates an error, and must be manually cleared before the next job.
The rest of your pages will have already scanned.
Repeat Every Time You Use it
