Paper jams only while duplexing

Single sided printing works great. When ever duplexer is used, first side prints fine but jams when it is sucked back into print second side. Have replaced duplexer unit, dc controller, drivers, have had a tech out for hours working on it to no avail. HELP!!

:-) exactly the same problem,

A user had loaded tray 3 with paper and nudged the slider at the back of the tray past the A4 mark, so the printer does not know what paper size it is getting and stops with the first sheet in the duplexer..

Back door broken, diverter gate broken?
I would look for something like this. did the tech clean the duplexers tires??

I would also try a different duplexer if possible-paper path sensor may be dirty or obstructed

I have a lexmark x6570 printer it will not print on both sides of the paper anymore it use to print on one side then pull the paper back in as use the other side


Please follow steps below on how to print 2-sided on your printer:
Printing on both sides of the paper (duplexing) automatically:
  1. Press printmastert_76.jpg.
  2. With a document open, click File > Print.
  3. Click Properties, Preferences, Options, or Setup.
  4. Click the Print Layout tab
  5. From the Duplexing area, select Use Printer Settings from the drop-down box.
  6. Make sure the printmastert_77.jpg light is on.
  7. Click OK to close any printer software dialogs that are open.

Printing on both sides of the paper (duplexing) manually:
  1. With a document open, click File > Print.
  2. Click Properties, Preferences, Options or Setup.
  3. Click the Print Layout tab.
  4. From the Duplexing area, select Manual from the drop-down box.
  5. Select the Print manual duplex instructions check box.
  6. Press Start.
  7. The printer prints the odd-numbered pages and the instruction sheet, which describes how to flip and reload the paper.
  8. Following the instruction sheet, flip and reload the paper with the printed side facing away from you.
  9. The printer then prints the even-numbered pages on the reverse sides of the odd-numbered pages, completing the two-sided sheets.
Note:
  • printmastert_78.jpg button is not functional with a Macintosh operating system. You can print two-sided documents with a Macintosh operating system by using the settings in the Two-Sided menu of the Print dialog.
  • Automatic two-sided printing (duplexing) works only with plain paper in letter and A4 sizes. If you want to print two-sided documents on another size or type of paper, use the manual duplexing method.
  • To return to single-sided printing, make sure the printmastert_79.jpg light is not on.

HP Laserjet p3005x printer - Just received this printer from used stock. Every time we try to print in duplex, the paper jams under the toner cartridge after printing the first page and then being sucked...


Hello, This problem is commonly caused by what is known as the (DPA) duplex pendulem assembly. The function of th DPA is to switch the direction of the paper in order to print the duplex side. The DPA sometimes will bind and not work properly which results in the paper jam you have described. See Photo Below.

In order to change this part, the printer needs to be dis-assembled. AN HP Certified Technician would be best to do this repair.

Oki C9300 - paper keeps jamming in the 2 same places, reads either 383 paper jam or non paper sense error. All drums and tonners are new, paper is loaded.


your getting a 383 paper jam, find paper in two different places.
See if it's a duplex related problem. print single sided documents, if that works, try printing two sided documents (it'll be the duplexer) if it only fails while printing duplex.

Also, check the back door. Make sure the back exit tray is closed all the way.

You can also have a paper jam in the duplex unit (open the front door), the duplex unit slides out the front. You can easily remove the duplex unit and run the printer without it.

HP 1320 duplex printing paper jam


Managed to solve this myself: I disassembled the printer and noticed there was a paper jammed in the duplex tray. Rolls were all ok, but the paper blocked the use of the duplex pathway. For disassembly help check the HP 1320 service manual, which you can find on the net as a PDF.

I am trying to print double-sided copy on card stock


HI there sounds like there is a blockage in the duplex area that is not holding any sensors down. Check the duplex area for torn paper, failing this it maybe a sensor problem which will then need a engineer.

Hope this helps
Thanks J

Samsung 3561ND fails to print double sided.


Do you use the duplexer a lot? It sounds as if the rollers inside need to be cleaned. I don't recommend doing this yourself as it involves lifting the printer off of the duplexer, and I don't want to be responsible if you accidentally drop the printer or you or someone gets hurt. But that's how to get to it; the offending rollers should be visible, and may be cleaned with a clean rag moistened with a multi-purpose cleaner. Alcohol is what's recommended, but I shy away from it as it's known to dry the rubber, and all you want to do it clean the built-up dirt and paper duct off of it. Let me know how it works, if you do it! If you opt not to, call a qualified printer technician.
