My conon printer mx340 says ducuments in adf error


Hi guys,
This error occurs when paper sensor in ADF = Automatic Document Feeder detects some paper inside paper path. Firs, open ADF access cover and check if some broken paper present inside paper path. If no broken paper found in paper path means paper sensor is faulty and you need got new ADF replacement. Thanks

I have a Canon Pixma MP780...it says it's offline and the printer screen is flashing 'please wait'. I've tried turning the printer and computer off and on, I've tried re-installing the printer but still...


Unplugging the printer from power and letting it sit for at least 10 minutes should clear the error, unless there is something physically wrong with the printer.

Printer is not working


It is possible that the FAX in the memory is causing the problem. Try unplugging the printer from the wall and leave it off for a minute or two to see if it will clear the memory

Try Canon support. Type your query. Click "Search"
Example: Type "clear ADF" (You may have paper or some obstruction in the Auto Document Feeder).

Was working fine now when I try to print it says "service error 6A00. Click cancel, then OK". I have done this several times, rebooted, turned printer off and on, and I can't clear it. The alarm light...


6A00 is a problem with the sheet feed unit.
Call Canon find out where & take it or send the unit UPS to the Authorized Repair Facility.
You will NOT be able to resolve the problem yourself.
Sorry for the bad news.

Hope this helps

On my Canon Pixma MP780 a vertical line appears on copies made using ADF


I tried the other solutions listed here - and no luck. After cleaning the inside of the ADF, like the manual suggested - no change. How are you supposed to do that anyway? Deep cleaning the inside of the machine also has nothing to do with it.

I finally figured out why things that I copied with the ADF had lines/marks on them, but those placed directly on the platen (big glass) were fine. When you copy with the ADF, the copy is not being made from the large glass area. Rather, there is a thin glass area right next to it.

Turns out, there were a couple of smudges (goo) on that thin piece of glass which were creating long vertical lines down every sheet. Cleaned the glass - problem solved!

Gosh, I hope this helps someone else save some time, and frustration.
