Canon MX850 - error code says remove document from ADF. There is nothing in it and I blew canned air through it. Can't clear error code. What else to do?

SOURCE: SUDDENLY THE ADF DOSEN'T WORK

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.

First thing I would try is to reset the device by turning the device off, and waiting a full 20 seconds, then attempting to restart the printer, wait for it to do its full boot up cycle and then try again, if that doesn't work I might e-mail, or call Canon.

Hope this helps,

I had the exact same problem. The Alarm light was always on and the screen said "Document in ADF. When I pressed "OK" it would read "Eject the document". Even after I placed paper in the ADF and the paper would feed the document through it, the error and the Alarm light was still there. I found the solution, Lift the cover to expose the flat bed scanner glass. Under the cover, there is a long white bar with two white tabs perpendicular to the white bar. One of the tabs was retracted. Pull on the tab until it is fully extended. The alarm turns off and there is no longer the error. Simple solution to a damn annoying issue.

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
