I had a paper jam and then the rolller bar will not engage properly. Tried to follow directions to put it back together but a extra spring poped out from somewhere. No directions in book. We have 3 springs one with roller bar assembly another on the right hand side at the panal and one unknown spring not sure where to put it. I have an engineer here with me who can not figure it out. He can build a nuclar plant but can not figure this complecated fax.

Paper jam after fuser replacement.


Since you reset the counter you reset your paper size .the paper detection flag ,spring that returns it to its h ome position knocked off. Check all your connectors and make sure the drive gears are meeting up. Most fusers have what they call a pivot gear. It has a spring that engages it to the main drive . Make sure there meeting up. Tip ,mark a gear and make sure it rotates. White out works well to mark a gear. You could have a bad part.

Epson Stylus Photo PX800FW paper jam


Got my own PX800FW.

Please note that ADF paper jam online docs of EPSON Aculaser 1100 http://www.epson.co.uk/gb/en/viewcon/corporatesite/products/mainunits/faq/2929/1393#toc6 are craph* more detailed than the PX800FW **** that EPSON is making users put up with.



I am having the very same ADF scanner jam issue (paper stuck directly when trying to feed into the lower rolls).

Initially I suspected the upper paper feed rolls (turning them requires rather strong force), but they were not the actual problem (see below).

If you want to inspect these top rolls, then remove the top flap
(use a screw driver to somewhat (and obviously carefully!) bend the plastic hold located towards the user panel side, then lift off top flap.

I then unscrewed its 4 screws.

To remove the main roller mechanism, you need to pull out (somewhat forcefully, but obviously carefully) the large white extended cog bar. Then push out the somewhat larger wheel bar from its flap-side plastic holder.

Now you\'re able to (while keeping a watch on the small white tab that\'s being drawn back by a spring) remove the entire roller skeleton.

I then proceeded with removing the end cap (fiddling with a screw driver - but watch out for some parts getting lost due to a somewhat strong spring!) and replaced the spring with a weaker one, and adding some washer plates reinforce the slightly weakish spring. I then ended up with a roller mechanism that was almost as strongly pressing the rolls towards paper, yet actually turning them ended up easier on the motor.


I then put everything back together, but an attempt with the newly replaced parts failed, too.


Then I directed my attention towards the main motor / cog mechanism.

I rather instantly had to discover that the main cog at the main ADF motor was broken, and this is very likely to be the reason for the ADF jam issue.
This rather flimsy black cog is made of plastic (and having some nice tiny predetermined breaking point holes to boot!! guess where it did break...) and sitting on a metal drum which seems to be rather strongly attached to the main motor axis, unfortunately.
I will now try to remove the drum, possibly with the help of hopefully successfully warming it via a hair dryer. Choosing to glue the original plastic cog instead doesn\'t sound like such a marvelous proposition...

Given the rather flimsy appearance of the entire printer a future EPSON choice is quite unlikely.

Paper jam for dell 1130 laser printer


Ive got a Dell 1130n that was jamming once it came out towards the top. if you take the top off (2 screws in front and 2 screws in the back) and the rollers right there at the back (once you get the top off) take that long "roller bar" and the springs that push up on that bar just slightly stretch them out and clean the rubber wheels with soap and water (allow to dry) and put everything back together. Also the wheels in the back could be cleaned too. If you open the rear cover there is another "roller bar", there are grey clips on each side that if you pull down the click into place, just unsnap the "roller bar" and clean these wheels as well. It has worked great for me so far.

Carriage jam


Hi there

Follow these steps to fix the problem

Unplug the power cord of the printer and open the cover to reveal the carriage assembly.

Squeeze the two levers beneath the paper tray together to remove the tray.

Slide the carriage assembly from the left side of the printer to the middle where you have easy access to it. If the carriage assembly will not slide, Push down the large black bar located directly above the rollers and then release it so that it springs back up. Now attempt to slide the carriage assembly to the right again. If it still does not slide, Locate the flat black component found directly below the rollers in the tray compartment. It should be lying flat, parallel with the base of the printer. If it is pointing upward, push it down.

Slide the carriage assembly over to the right once all of the above parts are in their correct positions

Lift the actuator arm, which is directly above the white and/or gray gear assembly at the left side of the printer. The actuator arm is thin strip of black plastic that is approximately 1 3/4 inches long and 1/3 inch wide. Lifting it and releasing it should restore it to its proper position.

Put the paper tray back in the printer. With the cover of the printer still open, plug in the power cord and turn on the printer.

Press and hold "Resume," then close the cover of the printer.

Paper jam at transfer roller with no paper jammed. Have cleaned rollers with 409


Had the same problem after cleaning the rollers also. Technical help was rubish. In the end I found some clues n fixed it. There is a flag between the rollers n if it gets stuck and or in my case the spring behind it came off, then the sensor thinks there is a constant paper jam. Undo one screw and get inside n check the spring n flag. I done this. placed sping etc back in place, put it all back together n bingo. Be carefull not to drop the screw inside and make sure the cog is properly engaged or you will get a funny noise. I can provide pics etc if needed.

Paper jam


I too have this infuriating problem and the reason has already been pinpointed very well it is indeed the front rubber pinch cam not grabbing the paper well. I have approached this problem from another angle... under the front sprung loaded flap on the paper tray
there are two compression springsapprx 1/2" in dia. Gently prise apart the 2 flap pivot (on the extended arms) to gain access to the springs ,pull out the springs and either replace them with slightly stronger ones or pull the existing springs apart to retension them and pop them back (long-nosed pliers or tweezers) this will restore the spring tension lost during use with the rubber pinch cam.

Paper not feeding properly


1. Clean the rolllers first.
2, Then on the upper half of the scanner, look for a pad with small leaf springs on it. That pad can be worn or one of the springs bent down. Look into there with a flashlight and see what is dragging on the paper.
Look carefully on the top and bottom half of the scanner, you have some type of partial obstruction.

Canon MF4150 Duplex Printing Paper Jams


I have just had the same problem on one of these Canon MF4150 machines.
The manufactures warranty on our machine had expired just one week before this happened so I had to fix this myself.
The problem we had (which is very likely to be the same cause as yours) is when we removed some torn jammed paper, it had somehow pulled off a spring from inside the machine. The spring was linked to the paper jam sensor.
It does involve a LOT of work to fix it, and unless you are very 'techy' it may be quite a difficult task to do this for the 'average' person.
I had to completely disassemble the machine: Take off the front first (lift up the cover and there is 2 screws at the front and 2 clips on the bottom of the machine) Then remove the 2sides and finally the top (screws should be easy to see, to get the sides off, un-clip along the front edges and gently move them outwards and slide them backwards to release the clips on the back) being careful with the wires going to the scanner part). Then look for the fuser unit which is near the top at the back, there is a black rounded cover over the fuser. To remove the cover, look for 2 small clips one at each side and unclip the cover and gently lift upwards.  Under the cover on the left side you will see a small plastic rod which goes from the left side to a small tab in the middle, if you look about half way along that rod you should see a tiny spring, make sure this is clipped on properly and that you are able to rotate the rod and it should spring back to the proper position when you let go.
Once this is done, put it all back together again and it should work fine.

I'm sure a lot of other people probably have this same problem too so I hope this helps someone.

HP laserjet P2015D , JAM LED in a solid state ??


Dear gentlemen,

Hope this helps you sort out the problem. Please check paper jammed pieces of paper remains from paper in to out paper path. Check if the paper is properly picked-up, else check rubber roller pick-up and the solinoid motors that control to fed on and off the tray to engage pick-up. Check paper path sensors if possible. If you can determine when is the paper Jam happens please advice. Other means you can also refer your manual and machine diagnostic menu which part of the operation the paper will jam.

Best regards,
