Duplexer I put paper in the tray, and now I'm getting a message that says "install duplexer." What is the duplexer and how do I install it? Also, it keeps referring to tray number 1, but my trays are numbered 2 and 3.

First what model? Second miss feed and jam are different, miss feed the roller can grab the paper, replace the roller putting a rubber sleave is going to mess with the feed system. Clean the rollers with alcohol

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

Make sure that you did not lower the duplex tray. Look into the printer where the paper tray goes and make sure the path is clear. The duplex tray is dropped by pushing on a green lever on the left front of the duplex tray. Simply push the tray up until if clicks and locks in place. This is the only reason I have run into with clients as to why they cannot insert the paper tray.

Check the C6200 Device Settings in the properties and make sure that the Duplex Unit is installed.

Clear the jammed paper as follows.

If the jammed paper is removed completely by using the information in the following steps, you can install the paper tray first, and then close the front cover and the printer will resume printing automatically.



If the printer does not start printing automatically, press the Go button. If the printer still does not start printing, please check that all the remaining jammed paper has been removed from the printer. Then try printing again.

Pull the paper tray completely out of the printer.

Pull the jammed paper up and out of the printer.

Press the cover release button and then open the front cover.

Pull out the drum unit assembly. Pull the jammed paper up and out of the printer. If you cannot remove the drum unit assembly easily at this time, do not use extra force. Instead, pull the edge of the jammed paper from the paper tray. If the jammed paper can not be pulled out easily, turn the jam dial towards you as you gently pull the paper out.

Open the face-up output tray. Pull the jammed paper out of the fuser unit. If the paper jam can be cleared, go to Step 7.

Open the jam clear cover. Pull the jammed paper out of the fuser unit.

Close the jam clear cover. Close the face-up output tray. If the paper jam still cannot be cleared, for HL-5130 and HL-5140 users go to Step 10, and for all other users go to the next step.

Pull the Duplex Tray completly out of the printer.

Pull the jammed paper out of the printer or the Duplex tray. Put the Duplex tray back into the printer.

Push the lock lever down and take the toner cartridge out of the drum unit assembly. Take out the jammed paper if there is any inside the drum unit.
Put the toner cartridge into the drum unit until you hear it lock into place. If you put it in properly, the lock lever will lift automatically.

Put the drum unit assembly back in the printer.

Put the paper tray in the printer.

Close the front cover.

The duplexer, which flips the paper to automatically print on the back side, slides into the back of your printer. Unplug the printer and slide the duplexer out to check it for jammed sheets. You might have pulled out a sheet or two in the main printer section and left one in the duplexer.
As for the top tray, the paper feed wheels ride on the end of a long lever that drops down to rest on the paper. It should be held up out of the way by a spring until the drawer is inserted, but sometimes the plastic nub that the spring pulls on breaks off. Lexmark sells a little kit of the spring and "bellcrank" to fix it. If your paper tray holds 500 sheets - a whole **** - you need part no. 56P1331 "Parts packet, bellcrank and spring, 500 sheet." For 250-sheet trays the part number is 56P1337. A web search for either part number will find you a seller.

The JAM DUPLEX message appears if you remove a sheet of paper from the face down output tray after only one side has printed.
The paper sizes you can use with the duplex printing function are A4, Letter or Legal.
If the paper adjustment lever for duplex printing is not set correctly for the paper size, paper jams may occur and the printing will be out of position on the page.


Open the back output tray.
Use both hands to slowly pull the jammed paper out of the fuser unit.

Close the back output tray.
If the paper jam cannot be cleared, go to the next step.
Pull the duplex tray and paper tray out of the printer.
Pull the jammed paper out of the printer
Put the duplex tray and paper tray back in the printer.

Hello
See if you have selected weight paper from the tray in the duplex mode.
Weight paper is selected in duplex mode only from the bypass.
So you check that the paper in the tray 1 or tray 2 must be plain paper and in duplex mode it can print normally.

Problem solved by simply uninstalling and re-installing the driver (with the same procedure as before... bah!)

1. Take out paper tray 1.
2. Remove any jammed sheets of paper you find there.
3. Once you have done this, reinstall the paper tray and try printing again.
   Note: You may receive a message informing you that another sheet of paper is jammed elsewhere in the printer. If so, please open the front door and remove the toner cartridge. Also open the rear door of the printer (and the duplex option if a duplex unit is installed). Remove any and all jammed sheets of paper you find. Then try printing again.
4. If the printer jams again with a 241 Paper Jam error message, look to see if it has tried to feed a sheet of paper out of the tray.
   

What is the exact error message shown on the display ?
Does it makes any strange noise when you start it up ?
