Print Problem error after 1/3 to 1/2 prints

I have a little more info on my printing problem.  In front of the Platten there is a long black plastic piece that tilts up and down as needed when printing.  If I reach in and hold this piece tilted up, my full page will print.  If I don't do it, it will stop after 1/3 to 1/2 prints.  There is a small piece underneath the tilting piece that runs on a belt right to left that makes this piece tilt up and down.  It appears that this tilting is needed to change carts. (Down to change carts, Up to print).  I only need a black cart as I'm printing a diagnotic test (hold power & Ready etc).  The small piece appears to move too far to the left causing the tilting piece to move into the wrong position.  Any ideas how to fix this problem?

    I think this is a common problem with the MD-5000. I'm searching for a fix now. I've lubricated the parts in question and am testing now. Since the problem is intermittent on my machine, I don't know if the promising results that I've seen will last.

This is not for changing carts, it's for the anti-curl function. You need to attach your printer to a computer, load the driver, try a test print from the computer, and check to see if the printer is reporting an Anti-curl motor error

Clean a KX-P7100 printer

The paper jam in theKX-P7100 is usually due to the paper tray.

If you pull the paper tray out you'll notice a black piece of plastic (located at the most front) with a cork like material in the middle. Try pushing down on this piece of plastic a few times. If it does not pop up immediately the grease that Panasonic used has become "sticky". The piece of plastic is removed by turning the tray upside down and pushing on the small plastic tabs that hold the black piece of plastic in. Be careful to not loose the spring that is located under the black piece of plastic or break the plastic tabs that hold it in place. Once you get the black piece of plastic out, clean it with que tips and clean the area it slides up and down in. Make sure to remove all the "sticky" grease. Once you get it clean, don't forget to stretch the spring to one more inch. the spring quality is awful at tensile strength. Then place the spring back in its place and push the black piece of plastic back in its place. You can add some light oil to the black plastic to make it slide better. After it is reassembled try pushing down on the black piece of plastic a few times. It should spring up almost immediately. This should take care of the jams that you are experiencing.

In addition, you may have to stretch the 2 big springs under the metal plate in the paper tray to one more inch. To access them, you'll have to unscrew the 3 philips screws under the tray (take a picture before :-)), take away the 2 blue pieces and take out the metal plate.

Now I'm able to print from the media tray without any problem :-).

Hope this helps!

My driver side window wont roll down, manualy, it rolls down on an angle. How do I fix it?

Thanks for the info, I think I can help. Roll the window down until it tilts forward just a little. Once the glass has tilted forward, do you see a tiny hole in the rear upper corner of the glass? I think your model has a small piece of plastic that hooks into that hole and rides up and down the vertical window track to hold the glass straight.

Removal instructions:

1) unplug everything and move the unit to where you can work on it.

2) Remove the paper, and remove the hinged lid (tilt the lid to the up position and lift directly up and off).

3) Remove the push button cover which lifts directly off - straight up.

4) At the top of the button control module is a recessed release clip. Use a flat blade screwdriver and push down on the clip. While pushing down, slide the control button assembly down. lift the outside edge up (there are straight clips on the inside edge). Lift up slowly as the connection cable needs to be unplugged. the cable itself unplugs. Just pull down evenly grasping the top blue laminated section. The blue goes to the outside (contacts go to contacts on the inside). Set the button control unit aside.

5) Using a #10 Torx screwdriver, loosen the two screws in the back corners of the glass cover assembly. Lift the glass assembly up (like changing an ink cartridge), and pull the front lip left and right forward - there are two clips at these locations. Pull forward and lift up. Remove the glass cover assembly off and set aside. Note, tip over and remove the scews (best to remove and put back in after the cover is back fully in place). In reassembly, be sure to feed the control button cable back through the hole, and that it goes back into place the way it came out (including folding back into the slot under the button control assmebly).

6) The black plastic cover has two metal clips visible. These are not the release clips (they hold a glass piece in place under the black plastic cover). The release clips are outboard of these metal clips and are two slots. Insert a small flat blade screw driver, and push the handle toward the center. While prying, lift the cover at that end up, pry the other end and lift the black plastic cover off.

7)While you're in there, you might as well clean the mirrors (THERE ARE FIVE OF THEM)and glass. At the front of the lamp on the botton, the lamp wires lead to a white two piece plastic connector. Unplug the lamp wires. Where the lamp is, toward the front is a black philips screw in the clear plastic piece that holds the front end of the lamp. Remove this screw, and lift the clear plastic piece with the front end of the lamp up slightly, and then pull the full lamp assembly forward and out. This will open the space to the mirrors and glass. Use a Q-Tip and small pieces of paper towell and glass cleaner to clean the mirrors and glass strips. I tried to remove these to clean them, but the metal clips were too tight.. better to clean it all in place. BE SURE TO CLEAN THE EYE!!!!!

8) Clean the bottom of the glass top assembly.

9) Reverse the above to reassemble. Be sure to plug the lamp back in, and the button control assembly. Leave the black plastic cover off.

10) Place the glass top assembly back in place, and snap it down before dropping the screws in the back holes.

Don't know why, but you should be good to go.

After doing the above if in a few weeks you get the same msg again go back in there and take the black top off the housing that the mirrors are in and leave it off!!!! sound crazy but it has been working on a lot of the machines that come in here.

Printing only bottom half of picture.

I had the exact same issue with mine! I didn't manage to fix it, but I know exactly what the issue is. If you open the printer, you'll find a black rectangular box above where the film fits inside the printer. This black box is connected to the board above it, and is supposed to press down against the film, and then against the paper for it to print properly. There is a little bar above the rectangular box, and there should be two plastic pieces on both ends of this bar. The bar is also connected to the gears, and when the gears move the bar, the two plastic pieces coming off of the bar push the black box down. When I looked at mine, only one of the plastic pieces was doing its job; the other one was broken, and was sliding on the bar. Tried some super glue, wouldn't work. I suggest tossing it out like I did, unless it's still under warranty or you want to try fixing the plastic piece so the printer head gets pressed down all the way.

Paper jam that I can get the small pieces of paper out

sounds like your jammed paper is in the fixing assembly. (the one on the right side, where the paper comes out printed very hot)
you are gonna have to remove it from the copier to easily remove the paper.
here's some instrutions.
remove the cartridge. then remove the platten glass. you will need to remove a small plastic cover on the left side of the glass. then just remove the glass. then remove a black piece of plastic that covers a cable. now remove the control panel. like if you were to remove the cartridge open the uper cover and there you should see a screw. unscrew it, then the panel must slide a little to your left and then just carefully unplug the flat cable. now you need to remove all the covers on the left side of the copier. (...ok they dont sell this particular model around here but if you do not happen to see screws on the left side then you may have to remove even the front cover). once done, unplug the fixing assembly, there must be at least two connectors that go directly to the power supply, then unscrew it, from two holes located at the top (where you previously remove the platten glass), on one side there should be only one screw and on the other two. once is unplugged and unscrew it should come out 'easily' Caution: It could be hot! now you gotta remove the top cover of the assembly just unscrewing the two screws one per side. it still it doesnt pop up it has some kind of metal locks you just need to push or pull depending on how they're located. once you get to this point (or even before) you should be really able to remove all the paper jammed in there. Good luck!

Paper jam in Canon MP460 printer

This can be fixed at home. It's a design flaw that locates a little paddle right on the edge of an infared light beam when the paddle is resting where it should be when no paper is in the printer. If they had extended this black plastic paddle ever so slightly toward the front of the printer, it would surely interrupt the beam as it is supposed to do. Raise the platten section as if you were going to change the ink cartridges. Locate the white plastic plate with 8 little white rollers along its front edge. About 1.5" from the right edge of this plate is slot about .25" wide, just under a metal bar going across the printer. Down in this slot is a little black plastic finger that gets lifted up when a piece of paper goes through. This little finger is the lower end of the paddle above. Poke gently on this little finger with a little stick or dowel rod. Make sure there's no paper under it. Put the lid down and try it. If still giving the paper jam error, you'll have to take the whole blooming cover off to get to the paddle. I put a piece of black electrician's tape over the paddle to extend it forward to be sure to interrupt the beam. The key to opening the cover is to start with the gray plastic pieces on each side. They move down toward the floor about 1/8" to come off. Be gentle. Try never to tip the printer on its side ink will run and make a mess. I highly recommend a pair of rubber gloves once inside -my fingers got green ink on them and it doesn't come off. Good luck.

Hi. Your printer may be in a need of basic service to clear up the jamming problem. The printer has comfiguration settings. If the configuration settings are correct, then there is no need to worry - just a basic service to the rear pressure rollers and front pressure rollers. Sometimes when the printer prints for a long time over months, then there is quite a lot of build-in paper pieces inside the platten assembly. Either if it jams, often there is sometimes piece of paper stuck below the platten assembly or in between the pressure rollers...

Black line down the page

Is the line on the front of the page or on the back? If on the back, you need to clean the platten which is the piece of plastic under the paper.

If its on the front, and you say "It lools like a rubber cover may be missing off of one of the rollers", could you upload a picture of this roller? I don't recall any covers on rollers in Canon printers.

Try this, print out a blank page. If line is still there, print out 10 blank pages. If line is still there and has not faded, this is unusual and may need servicing. There may be a problem with the encoder strip (it's a clear plastic strip with black lines running the length of the printer slightly behind the head), Try cleaning it on both sides with a little windex on a q-tip. It's delicate so be careful.

If the line looks faded after printing 10 blank pages, some ink has dripped onto something that is contacting the paper. This could be a roller, the bottom of the head carriage or even a hair or piece if dust that is stuck in the machine or on the bottom of the head. In this case, I would recommend cleaning everything. Revove the head (tell the machine you're going to replace ink, and when it moves the head into the centre position unplug the power cord.

Remove the head and clean off any dust or hairs on the bottom. Run a Q-Tip along the bottom of the carriage assembly wherever you can. Clean any accessable rollers. If you can get at it, clean the wiper on the purge unit (the unit the head sits over when it is parked), as well as the seals.

Reinstall the head and ink, close the lid, power up and retry printing.

I hope this helps. If not, there could actually be a fault with the printhead or one of the circuit boards
