Paper jams when folding 8 1/2 X 11 ivory paper; less often with white. Tech says it's a paper issue - so whose colored paper (brand) will work - or is it a design flaw?

Hi,
There are a number of reasons why the paper would jam at registration. First off, if the paper is completely flat & straight it is probably a feed issue or paper detect issue. There are 2 little black photo reflectors before the rollers in the centre of the feed path. These sensors can get covered with paper dust & may need cleaning. Also try feeding paper from the manual feed tray & see if it jams. If you have jams from both cassette's & manual feed then its most likely a sensor of feed issue. If its from one tray only then the sensors in the vertical path may be dusty with paper dust or worn pick up & feed tyres. There is also an issue with the feed clutches in the paper pick up drive unit which can fail & have been upgraded.
Secondly, if the paper is Z folded at the registration rollers but before the fuser then it could be the primary bed drive gear. This gear also drives the secondary belt unit located in the right hand door assembly.
Hope this helps.
Dave.

The jam indication is set because the sensor(s) detect one. This could be due to a buildup of paper dust, a small bit of a sheet that tore off and got lodged deep inside when removing a previous jam, or damage to the sensors if the jam was removed forcibly by pulling the sheets out from the wrong direction.

Everything you checked sound good. Might be printer software problem, and needs to be re-flashed. Software only available from secure web site that a technician would have, see what it cost if to much buy a new one with extra bells and whistles !

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

Printers can be finicky. Ours at church works with no problems until we bought a different brand/weight of paper, then it jammed frequently. That is the first thing I would check. Then, the next thing is the rollers can get slightly worn. When you're talking less-than paper thickness tolerances, it doesn't take much to make a difference between working and jamming. Unfortunately getting these worked on is close to if not right at the cost of a new one.

HELLO WHAT JAI INCLUDING THOSE OF A QUESTION PAPER JAM = if the paper fits in the oven = problem = must clean separation or the ressord that holds fell, puts in place if it is a question of stuffing at the beginning of cycle = ventillet paper i hope that it works for this anomaly

This jamming has to do with third-party toner cartridges being used. I had this problem using Xerox toner cartridges and found that I would have no jamming if I used at least 2 hp-brand toner cartridges and the rest Xerox. I then used a different brand of 3rd party toner cartridges that would not jam as long as just the black cartridge was a genuine HP black toner cartridge. This issue has been confirmed even by the manufacturers of the generic toner cartridges. Hope that helps!

There is probably a crinkled piece of paper stuck in the paper path somewhere causing an alignment issue. Open all the access panels you can and check everywhere for a small piece of paper. Check really good as this issue can be caused by a VERY small piece all folded up.

See here. Also here.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

hi
follow these steps
1.checked for and remove any obstructionsfrom paper feed tray.
2.tilt and shake printer..checked for any rattling noise..checked for any foreign objects inside printer obstructing the paper flow.
3.Take a sheet of paper ..fold it length wise 3-4 times to make it a thick.insert this into paper feed tray...move it left and right a couple of times..unplug power cable and replug it after 10 seconds...try printing ...if it does not work,,,,contact tech support 1-800-332-4120...ur printer is brand new and under warranty cover,,,they would replace it for u.
goodluck:))))

As several previous posts said there was a pieces of paper folded up inside. Per a previous post remove the sheet feeder rack. At this point I removed the two outside screws (of the three) on the backe. After this the whole top lifts about 3/4 inch (19mm) to give your fingers more room to clear it. Looks like she will print another day.

Thanks for the tips on here.
