Support Code 2804 on Canon MX922
[ Edited ]

Support Code 2804 MDF failure to scan.  'doc size not suitable for duplex scanning'.  Win 7, Pixma MX922


Tech support tried valiantly to figure this out but could not, so I'll share my solution.  I suddenly kept getting Support Code 2804 failure on MDF after duplex scanning several hundred pages of docs to PFD files.  Three calls to TS yielded nothing but a guess that document paper had some kind of security to prevent scanning.  I've not heard of that, but it was a clue that I researched. 


Here my answer to the 2804 failure, but it's not good.  Scanner feeds first page, and displayed the error saying doc size not suitable for duplex scanning.  All you can do is clear the error  


Measure your document.  Printer docs say ADF will work with 4x6 and 8.5x11.  Read that literally.  My financial institution switched to a 8.5x10.3 page size.  When I got to those docs, the error began.  I have not yet experimented on the MINIMUM document length, but the 10.3 definitely fails. 


This appears to me to be something that could be fixed.  Not sure if is hardware of software, but is a definite drawback to an otherwize good scan process.
