Canon imageclass mf6530 paper jam error wont go away

If the message PAPER JAM comes up on your LCDdisplay, first deal with the paper jammed inside the machine and then deal withthe paper cassette.If after removing the jammed paper inside the machine and in the cassette and the LCD display still indicates a paper jam then unplug your printer and plug it in again. If you still see a message that says paper jam, there is probably a problem with your sensors and you should contact a technician to repair the sensors on the machine.

Check where that u removed the paper and see if one of the sensors is stuck or out of place. also look for a piece of paper. you may have to get a flash light to see better

SOLUTION:
DO READ. sometimes there are two papers, but we're aware of one only.

I found that my printer stopped since a paper jam occurred. Well, I opened the door, removed the cartridge and found an A4 paper stuck. I gently pulled it and the paper was out.

But still printer won't start saying that a paper was stuck inside it. I tried every mean to find (in back outside door, inside, outside). Searched internet, shook the printer sideways, upside down, but nothing.

But lo, behold, in the top outside bin (where paper just comes out), I pulled the rollers (they don't fully come out, but just drop a bit), and found ANOTHER a4 paper (i.e. two papers had been jammed inside and I pulled out just one).

Also, I'd like to add, at another time, I fed a small a paper (about 3 by 5 inches) which was just lost inside printer, and showed a jam, that paper too had been stuck here only, in the path just before where the paper comes out of small rolllers.

So, that's it my friends, hope it helps.
