Found the cain has chewed the rubber roller that guides chain andjacent to lower fairing. does it supposed to roll and rotate with the chain hitting it?

If nothing happens no carrier movementor paper feed you probably have a bad keyboard.
If the carrier moves but no feed the index motot may need to be lubed.
If the roll moves but the paper dosen't you may have debris on the paper tray or bad lower fed rolls.

Hi, is this valve timeing or ignition, you are doing, anyway with the piston at tdc and the lower marks aligned on the caseing and the rotror, insert the camshaft into the head with the cam lobes pointing downwards so the valves would be closed,place the cam sprocket over the chain and locate the mark on the sprocket upermost to align with the cut out on the rocker cover, you may. Then have to flick the cain over the sprocket using a screwdriver until you align the marks exactly together, next check the lower marks have not moved and both the top and the bottom marks are alinged exactly with each other, next turn the camshaft slightly to align the bolt holes and fit the 2 sprocket bolts using a small amount of loctite or similar, tension the chain check for realignment of marks and rotate the engine using a spanner not the kickstart to check it rotates without obstruction, when you are happy it does then you can attempt to start the machine

The rubber roll is supposed to do it. Since it is clean, pull out some tape and try again. Otherwise, please contact our help desk. The numbers are at dymo.com.

No I think the tensioner is loose. Or chain hitting side.

The Solution One thing you should always do is clean the three paper feed rollers. To do this, take out the paper, get a moist cloth, and wipe them strongly.
Don't use alcohol. It's better to use plain water, because alcohol gets into the rubber and can wash out the rubber softeners, making the rubber harder, which is not what we want. So use a cloth that is moist, but not dripping, with water.
While you wipe one roller, push down on another with a finger and turn the rollers around slowly, so every bit of them is cleaned. Don't forget the narrow center rollerit also has a small rubber surface.
Sometimes this brings the printer back to work, but after more use and more time it usually doesn't. The remaining reason why the stupid thing doesn't feed paper is that the two springs pushing the paper against the rollers are too soft to begin with and, moreover, lose some of their spring force over time.
The springs have an outer diameter of 15 mm. If you can get some similar springs that are somewhat stronger, but under no circumstances more than twice as strong, replace the springs. If not, there is another way.
Since the springs are much longer than they need to be, you can take them out, cut them exactly in the middle, then use two of the fragments in place of one. In addition you can stretch them somewhat.
Step by Step Instructions You need only an ordinary screwdriver and pliers to cut the springs.

1. Remove the paper and the two cables from the printer and turn it around, so you can look into the paper tray.
2. Push the expendable paper holder in, so it's out of the way.
3. Use your thumb to bend the inner paper guide forcefully forward and to the left, until it bends enough to slip out of the right bearing hole.
4. Then pull it to the right to take it out of the left bearing hole as well. It should now move forward a little and allow you to see the two springs.
5. To make even more room to work on the springs, reach for one of the rubber rollers and turn it down (i.e. rotate the roller downward), until the mechanism opens the gap fully.
6. Use the screwdriver and one finger to shift the springs out of the lower hole and push them onto the conical rest on the inner paper guide you have just loosened, then pull them out. Don't use so much force that you bend them permanently.
7. Remember the length, then stretch both springs and let go again, until they are about one inch, no more, longer than they were. Repeat the stretching and increase the force until you have stretched them enough. This is actually not all that important, so don't overdo it.
8. Take one spring and turn it such that you can cut at the exact middle of the spring. Cut the spring in half. Repeat with the other spring.
9. Roll two fragments into one, so you get two shorter, but double springs.
10. Use your finger and perhaps the screwdriver to push each double spring onto the conical spring guide on the loose paper guide, then maneuver the lower end of each spring into the hole on the lower side, so the springs are in place again.
11. Push on the loose paper guide from above to check that the springs are properly seated and move correctly.
12. Push the loose paper guide into its bearing holes again, first left, then right. For the right side you have to bend it again strongly, so you can get the paper guide back into place.
13. Before you test the printer, switch it on once without paper, so the rollers move back into their normal parking position.
14. Put the paper back in and test the printer. Enjoy!

If the printer won't "pick" the paper, open the back of the machine and look for torn pieces of paper obstructing the path. The paper should be all the way back against the stop so that the rubber rolls will contact the paper when the paper is lifted up against them. There should be no paper bunched up behind the access door. If the paper is against the stop at the back of the machine and the rubber on the roller wheels is ok (mine has three rubber rolls on the right side and one on the left plus a couple in the middle without rubber) then there is a possibility that the mechanism that moves the paper up against the rollers is not operating. You can observe the paper action with the back off by putting one sheet of paper in the tray. Watch as you press and hold the second button (paper) - the mechanism should lift the paper up against the rollers and feed the sheet out the back (because you have the access door off to view). If the paper is not lifted and taken out, the printer might be repairable by repairing the part that has failed - take the printer apart and look at the mechanism. I doubt that you can find parts for it so if it is not simple repair, it will probably cost too much to repair. The paper has to be far enough into the tray so that the rubber rollers catch it - for 8.5x11 paper, the paper should be a little over an inch from the forward edge of the tray when it hits the stop (the paper guide will be approximately 1/8 inch in from that same forward edge.

Very often burrs are created on the drive links when the chain comes off, this explains a fairly easy method of removal.

Other possibilities, can you rotate the clutch dum without the chain? Can you rotate the sproket nose?

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH

Thank You for using FixYa.

If pictures are rolling during normal playback, just check one thing first. Open the Cassette flap and see the condition of the tape. Is it chewed and stretched at the bottom? If yes, the problem is a worn Capstan / Pinch roller in the VCR. It is cheweing up the lower edge of the tape, and therefore the VCR is not able to process the 'Control Track.
All you need to do is replace the Capstan / Pinch roller.It is a big (approximately 1 inch high by 1/2 inch wide Black Rubber roller inside the VCR. REPLACE. Problem will be solved.

Does it do this with other television sets? If so, then it indicates the problem resides in the VCR. Rolling as you describe suggests either the VCR isn't producing a clean enough vertical sync pulse in the video signal, or the TV circuitry isn't processing the pulse properly. First, try cleaning the heads (not just the video head, but also the audio/control head which is to the right of the rotating video head. If this doesn't fix the problem, an electronic problem is likely. Unless this is a high dollar unit, repair is not recommended, as VCRs of the last 10 years or so are essentially disposable. I've done some looking on the 'net regarding copy protection, and it doesn't look like this is an issue here.
