    Once I found out, the bottom tray have sensor's that cous the printer to stop printing. so I change the TRAY assambly and is working very good less jamming.

    Yes I set the media correctly, and the plain paper we found the problem... the little rollers from the trays they have to be clean, if they where use before on teh wristband, we clean it alcohol, and works move the the tray wristband to the first tray. and is working a lot better. , Guys thank you for your suggestions.

    Before you print, do you set the print media to plain paper?

    The labels and wristbands don't jam, but plain paper does? What if you move the plain paper to a different tray?

You can replace those rollers. They wear smooth very quickly. In a pinch you can also peel them off the hub and put them on inside out. It will give it traction. It sounds like you already know about the little sensor in the trays themselves. I've seen them pop out of position and cause those probs. I don't think they could have made those sensors any cheaper if they had tried!

My Lexmark c534n printer keeps jamming. I have changed the rubber rollers and the photoconductors. However, the paper will not even go up into photoconductor area. The rollers do try to push the papers...

The fuser rollers might be damaged. Check if the fuser rollers are damaged because if they are they can cause the paper jam, and might need to be replaced.

Hi, my lexmark T640 is saying 202.06 paper jam, check rear door. i have opened it and there is no jam, there is no paper anywhere and have pulled all the trays out and there is no jam. what do you suggest?

This jam is refering to back door, jam in fuser (hot bit) Double check no paper is wraped around fuser rollers.

These machines have a fuser at rear if you look at he fuser from the back, on it you will see, two thick fuser rollers (ones rubber), paper runs threw these then it hits a little black switch (your machine thinks this switch is activated) and then a series(3,4) of small rubber exit rollers, this switch (between middle and left) can get damaged it also likely that a piece of paper is concertinaed in fuser.

On a T642 prints out first three sheets just fine but on 4th it never makes it to the fuser. The paper curels inbetween the fusers and toner. 201.32 error

The error 201 means exactly what you are getting;
a paper jam between the printer input and exit sensors.

It is common on these printers for toner to build up on the fuser input guide and eventually gets so big as to catch on the leading edge of the paper,

you will need to scrape the encrusted toner off of the guide.

If the device has done a large volume of printing (say over 100k) it may be a faulty fuser assembly.

I have a paper jam on my Pitney Bowes 1630. The

Good Luck, When the paper is stuck in the back, it is in the fuser and you may be able to get the paper out, but probably the drive for the fuser is messed up, which caused the jam in the 1st place, if you get the paper out, the next one through will probably jam up again. Technicians usually just replace the fuser. Oce is the repair entity for these machines now. 1 800 2423 5556

202 pam jam

usually it means that a sensor in your fuser is bad. If you have a P.M. Kit replaced the fuser and clean the printer.

but before you do, make sure that you have cleared all jams, including in the fuser.

Its probably time for a Preventive Maintanence

Brother 4100e paper jam

Can be tricky people usally damage the fuser rollers removing this jam with pliers/tweezers, it has concertined and stuck after fuser rollers and before exit rollers it will be stuck on the switch best bet is to dismantle properly and remove fuser then dismantle fuser and remove jam, another thing to be concerned about is why did it, three seneraros, Damp paper going threw fuser dries and crincles(use fresh paper from sealed packet), fuser is worn(have fuser replaced), just a bad bit of paper (just have fuser jam removed. Fusrr runs on 240v, covers break easy

Paper Jam

The fuser unit has a pape sensor. If, for some reason, the sensor is stuck, the printer will read a paper jam. Open the rear door and inspect the paper sensor located in the fuser assembly. See if it came out of it's original position or if there is something blocking it from moving freely. Good luck.
