I have a Canon PIXMA MG3620 with a paper JAM - a thin strip the entire length of an 8 1/2 x 11" page tore off during printing and is wrapped tightly around the platen. I've been trying to REACH it from the front with no luck and it's not reachable from the rear of the printer. I can't figure out how to open the printer so I can access the platen. Can anyone help?Look on You Tube.

Notice that they never tell you to take apart the #$%*&^ printer.
You just have to find the paper a and pull.
And it is the same story for most other printers.

Here is the full list I found.

There are over a hundred, most make reference to either that model.

Maybe the MAN is telling you to buy another printer. The model you have is now on sale for about $50. When vendors start selling printers at low prices, repair and recovery become less productive it your time has value. The ink is more than the printer...

IMHO printers have turned into Bic lighters...when they run out or have issues you just throw them away...There's absolutely NO way to pull out this piece of paper - it's about a quarter of an inch wide and 11 inches long. Believe me, I've tried - it's in there as tight as possible. I've tried to slice it so I can grasp smaller pieces with long TWEEZERS but I'm afraid I'll score the platen if I keep working on it that way.

There HAS to be a way to get this freakin' thing open, doesn't there?? Short of a sledgehammer? (which I'm about to try next!) There are a few screws on the back but nothing comes apart (at least on the outside) so that's useless....

I've taken printers apart before - been dealing with recalcitrant electronics and mechanical gizmos for decades - but this one just has me stumped. I hate to throw in the towel and buy a new one - waste does not come easily to me - but when I do, it's likely NOT to be a Canon. I've only had the printer since this past Christmas and this problem has been going on for a few months! Before you destroy it, you can spray a mix of water, and alcohol. The will dissolve the paper and provide some lubrication. UPDATE (in case anyone CARES, lol) - after several uses of the printer's scanner function, I just opened the front of the case to see if the alcohol tip would work next and the nasty piece of paper had unrolled itself. Turns out it was caught in place by an errant sticky bit from an ink cartridge - guess I didn't fully remove the "pull to use" tab when I changed cartridges last time. So, my bad. But thanks for your advice! Good news...thanx for the update
