Canon Pc720 Copier Paper Jam

We have a Canon Pc720 and it displays a paper jam, however there is no paper jam. I replaced the paper feed sensor for some reason and that didn\'t fix it. I was reading about a "paper path sensor". Can you tell me where it is located on the copier and where I can purcahse one please?





Thank You,





Scott Borgmann

    I have the exact same problem with the same model copier. There is no paper jam and I can see no broken parts. Any help would be appreciated. JC

    I have a Canon PC 720. I removed the cartridge and replaced it and I get a rumbling noise and no paper feed then the error light.



    I don't have the operating manual. Any clues?

    Cannon PC720, I found the spring, and the post that is now hookless, but how do you get hand & tool in such a close space?

  • SJILLEDWARDS Feb 25, 2009

    I HAVE FOUND THE SPRING. . AND I CAN SEE WHERE TO CONNECT IT TO THE METAL PART.. CAN ANYONE GIVE ME ANY DIRECTION AS TO WHERE THE PLASTIC PART SHOULD BE.. THAT IS STILL THERE OR HAS BROKEN OFF.. ANY HELP IS APPRECIATED... THANKS IN ADVANCE.

    THANK YOU REPAIRMAN99 (Steven). Your solution was very detailed, extremely helpful and right on the money. Best of all it worked. From your description we were able to see exactly where the problem was (wouldn't have had a clue). My husband used the existing spring and was able to fix the problem.



    We were ready to buy another machine or call a repairman - you saved us a lot of time and aggravation. Thank you Repairman99 and thank you FixYa.

The problem with the paper jam (but not feeding) is that a small
piece of plastic that holds one end of a spring the causes the feed
gears to push against the powered gear on the back side of the toner
cartridge breaks off. So the unit does not feed (no pickup rollers
etc) and it thinks there is a paper jam (no moving paper). Orienting
the front as the side you work at, the back being the back, the
feed being the side the paper goes into and the output being the
side the finished copy comes out, open the unit. Looking into it
from the output side almost to the input on the bottom notice the
small hairlike things sticking up. Move to the left (back of the
machine) and see a few white gears all hooked into this gray metal
housing that moves up and down about 1/2 inch (It pivots). At the
top input side of this metal you will see a part of the metal that
stick up and has a small slot in it. the spring used to hook onto
this and the other end hooked to a small piece of plastic down and
more to the input side a bit, onto the upper input side of the white
plastic part that houses a shaft to a roller (fat little spring
about 1 inch long). the plastic part breaks off and you usually
can't see that a part was even there. The spring will still be in
the area. If you are handy, you can figure out how to fix it. I got
a longer spring (same strength) bent the metal toward the back 1/4"
and ran the new spring from there to a 1/16 hole I drilled in the
plastic side next to the circuit board (down low and back). I shaped
the end of the spring (where I drilled)to keep it more inside and
not hit anything. Works fine.

    Brilliant! I fixed my PC 720 in nearly the same manner as smurf313. I fed a small wire through the opening that holds the black plastic piece that sits below the grey metal housing, then up and through the lower loop of the spring. The wire should be tightened so that the grey metal housing is in it's position where the back stop is pulled down against the plastic that holds it in place. The spring should be in it's relaxed state in that position, so that it stretches when the gears are pulled down. Thanks to repairman99 and smurf313 my PC720 is working like a charm again!

  • wfoults Jul 07, 2011

    Thank you so much, I was able to drill a small hole and "tie" the wire to the plastic just below where the plastic hook was. Awesome, thanks!

    Holy cow, it worked. Haha! Thanks so much. Used these instructions to fix a PC740. Didn\'t have a drill or any thin wire on hand, so was able to use a bread tie. Go figure! :P

Thanks, Repairman 99. I had the same problem. Using your detailed instructions above, I located the spring, and the hook/slot on the gray metal piece which you described. But I couldn't find where the other end of the spring had been attached. Nevertheless, I used a piece of flexible wire to attach the bottom end of the spring to the black housing just below. Put the wire through the bottom end of the spring first, then fed the wire through the space in the black housing and twisted it tight. Then attached the top of the spring to the gray metal hook/slot, and closed. I'm back in business. And I hope that this method of reattaching the spring may be helpful to others.

    Thanks also to Repairman 99. I actually used the same spring and just opened it up a bit with some pliars, drilled the 1/16 in. whole in the white plastic housing and ran the srping from the gray housing to the hole I drilled. It took a few tries, but with a good pair of slim needle-nose pliars, I did it! (And I'm not very handy at all!!)

    Thanks to Repairman for the "map" and to smurf for the simple solution. Mine is 15-16 years old and never had a problem until last night. Fixed it this AM and it works just fine.

I think you are looking at the wrong direction. If the paper jam occured just after you pressed the start button; and the paper did not leave the paper cassette then the paper sensors are working correctly. This is because the sensors are expecting to see the paper coming but did not therefore initiating the jam signal.

Check the paper feeding roller and the transport roller if they are worn out due to aging.

There is a black plastic piece that sits on top of the grey metal housing.If the spring is still present, you can unhook the plastic piece, slip one endof the spring over it, the other on the metal hook that holds down the gears andyou are done. No need to rehook the plastic (just leave it floating) everything fits. Works like a champ. I purchased this copier in 1998. Not bad for a 15 year old copier!

Repairman99 has the correct solution here as my Canon PC720 Copier went down yesterday afternoon and I had no idea where to turn too. After some searching I found the link here to Repairman99's solution and starting looking for my problem. First off early on I thought maybe it might of been the dust inside the unit so I brought up a portable air compressor and blew out all the dust. Didn't help but later on checking the unit inside as thorough as I could I found the sprong spring Repairman99 and others spoke about here but could not find exactly where the broken plastic piece was. Thought about drilling a hole to attach the spring as others mentioned but after thinking about it decided to use a Nylon Cable Tie instead as I have a few different size bags of them in my shop as they always come in handy and are strong. I thought why not and picked one of the skinnier longer ones about 7 inches to wrap around through one end of the spring to keep it snug with the other end attached to the gray metal piece as it was from the factory. Just tied the bottom of the spring snug and out of the way. My Canon PC720 works like brand new again thanks to Repairman99. Just to mention in my search on the net it looks like many have junked their PC720 Copiers for the exact same problem. I almost faced that situation and found that there was nothing out there for sale that compared to this machine as many were complaining about the newer models that they did not come even close to working like the PC720. Many on the net said the PC720 could not be repaired as there were no parts available. I have owned mine since buying it brand new in 1998. It has worked flawlessly for almost 12 years. Only bought one Toner Cartridge in 12 years. Have been filling my own 2 Cartridges with toner bought on the net with no problems in case other PC720 owners were thinking about it. Very easy to fill and works like a brand new cartridge.

Canon PC720 copier


Looking at the copier where the paper comes out of, there is a switch to open and close it. Pull up and look on the left side in the back. There is a little spring that comes off, or breaks, or the plastic that holds it on breaks. THIS CAN PAPER JAM THE MACHINE AND SEEM LIKE A MAJOR PROBLEM. ALL IT IS IS A LITTLE SPRING. Hope that is only your problem.

Depends where the paper is stopping. The fact it is feeding suggests that a sensor isn't stuck, most likely worn out feed, pickup and seperation rollers.
