funny thing, just had the same problem on a Canon mx850, one year old. the cause = a serious paper JAM. My solution, i freed all the paper around the two little black spongs under the inks cart. then, i turned the printer on, waited for it move the ink cart to the middle, after i unplugged the printer so that the ink stayed in the middle. this permits you to move it freely, and have the room to work on the purge system. 5c20 is the pruge system not working correctly! i actually had to take apart my printer, opened it in two to find that the little motor that moves the purge system just got unplugged, probably by the paper JAM!. simply replugged the little motor. before trying this, behind the two black hard sponges, under the white squeege that moves back and forth; is a little black wheel, with uneven teeth spaced on it. this only turns clock wise direction. must likely it's stuck, needs to do a complete turn to be realigned. clock wise only (try to move it if your not sure what side is clockwise, don't insist, it's not that hard to turn the right way!!) now, when you turn this wheel, the squeege moves back and forth and the sponges go up and down, alernating with the sponges. it should become easy again, and the problem should be alright!
it's to be noted that, i won'T open the printer like i did, if is just out of the box!! or still under warantee.
i live in the middle of no where, and i had nothing to lose in trying to fix it myself.
hope this helps, write for more questions
