I have a 2000 that  runs fine on regular bond but will jam nearly every time on mylar. I get the j-14 error at the fuser...any suggestions..all of my other 2000's seem to be fine doing mylar. |

| What size sheets are these and how far do they go through? I would think you may be having a problem with the sheets building up static and "dragging" causing a exit delay. Give me more info about this problem and I will be glad to help you out. |

Static is the biggest cause of jams in the 2000. Mylar is the worst. Get some Brillianize and clean the paper path well. www.brillianize.com if you still have issues try this......
Facing the back of the machine on the far left of the fuser bed is the sensor that causes the J-14 code. Check the sensor out. Make sure it works and is in position. Make sure the flywheel isn't bumping it.
Sometime the little orange rubber wheel in the middle lower part of the Fuser exit can not rotate properly and cause a J-14. There is a fly wheel at the far left end of the fuser bed. The other end of it is connected to the orange roller. The shaft that turns it can slide left to right sometimes. Sometimes the flywheel bumps the sensor and causing a delay in the fly wheel rotation causing the J-14. Best way to see all this is to take off the rear panel of the fuser area and also the lower rear panel where the controller is. And then finally the left side upper panel facing the back. You should be able to see what's going on.
Solution - the small thin orange wheel on the middle of the Fuser bed exit needs to be removed. Simply use some snips to cut it. Then connect the small wheel to the bigger paper feed roller to the left of it. I've used nylon tape. Seems to work fine.
Ok now you wont get J-14s anymore. there's another exit sensor that will turn the machine off if there really is an exit jam. So you don't need to worry about messing up the machine or starting fires.
This has also fixed trail edge haze problems at the same time.
It has also fixed image drop-out issues on long sheets caused by media lifting away from the drum surface. That happens because the media forms a ripple because it's not laying flat on the fuser bed... all due to that orange wheel setting higher than the other fuser exit rollers and not allowing the media to stay perfectly flat. |

Good call Neil. I have actually done a similar fix to those pesky 2000 s before.
J14 is absolutely the exit pulse encoder not turning while the print is exiting. The stinkin' 2000 uses 2 exit sensors. The normal hi-lo exit paddle and this alternating hi-lo-hi-lo-hi-lo clock sensor. Due to the design of the fuser (oven) the engineers wanted to be sure if a jam occured that it did not spontaniuosly combust. That would be bad.
