I am trying to print and the paper jams from one side

Hi,

Please clear out the paper jam by removing the tray and removing any pieces of paper stuck in the printer. You can also open up the back of the printer and remove paper as well. Then, try to print on both-sides again. If your printer has multiple trays, try switching the source tray prior to printing.

Thank you.

check between the rollers there will be small bits of paper jammed in that is the reason.

Issue
During printing, the paper becomes stuck in the all-in-one and the error message 'Paper Jam: Clear jam, and then press Enter' displays on the control panel display.
Solution
Use the following instructions to clear a paper jam from the product:
Step one: Check for and remove any loose paper from the In tray
Do not try to remove jammed paper from the In tray. First remove any loose paper from the In tray to avoid worsening the jam.
CAUTION: Always try to remove jammed paper from the back of the printer first to avoid mechanical damage.
Step two: Clear the jam from the back of the printer
Follow these instructions to clear jammed paper from the back of the product. If the product is equipped with a two-sided printing accessory, skip to that section.
Remove the rear access door to clear the paper jam

1. Remove the rear access door by pressing the buttons on the side of the door and pulling it toward you.
Figure 1: Removing the rear access door

2. Gently pull the jammed paper out of the rollers.
WARNING: If the paper tears while removing it from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the product. If all the pieces of paper are not removed from the product, more paper jams might occur.
3. Replace the rear access door. Gently push the door into the all-in-one until it snaps firmly into place.

Remove the two-sided printing accessory to clear the paper jam

1. Remove the two-sided printing accessory by pressing in the buttons on the sides and then pulling the accessory toward you.

3. Gently pull the jammed paper out of the rollers.
WARNING: In the rare occurrence of a severe paper jam, you might need to remove the face plate from the front of the automatic document feeder and lift the pick assembly to remove torn pieces of paper from deep inside the automatic document feeder.
4. Close the cover of the automatic document feeder, and then reattach the document feeder tray.

Step four: Verify that the print carriage can move freely
Follow these steps to try to move the print carriage.
CAUTION: Do not force the print carriage to move if it is out of plain view or feels stuck. Forcing it may damage the printer.

1. With the product turned on, open the print cartridge access door. The print carriage might try to move into the access area. If so, allow it to move to that position.
2. Without turning off the product, unplug the power cord from the back of the product. Unplug the power cord from the power source. The power cord must be unplugged to allow the parts to be moved by hand and to reset the paper feed mechanism, without the risk of an electrical shock.
3. Looking in through either the print cartridge access door or the output paper tray, make sure the print cartridges are locked into the carriage and have not come loose. Also, make sure that there are no obstructions under or around the carriage to block it from moving.
4. Make sure the print carriage can move freely across the width of the product by gently pushing the carriage to the left and then to the right. Clear any obstructions found.
You may have to reach through the output paper tray to access the print carriage.
5. Close the print cartridge access door and plug the power cord back to the back of the product. Plug the power cord into the power source.
6. Press the On button to turn on the product.

Step five: Reload and test the printer
After you have removed the jammed paper, make sure the product is still functioning properly.

1. Reload the product with plain paper.
2. Peform a self-test by pressing and holding the RESUME button on the control panel until the product begins printing. A test page prints.

Step six: Service the printer
If you have completed all the steps listed above and are still experiencing a problem, service the product.

try turning off the printer for about 10 sec. to clear its memory and turn it back on.. then print again

According to the LexMark support page, this is most often related to not getting the print cartridge assembly properly positioned. (Left and right sides not fully in place). Another possible source is paper in the output tray when using the double sided printing feature. (This leads to grabbing an extra sheet when it tries to retrieve the paper to print the second side. Paper stock thickness will change the number of pages printed before this happens.).

I hope this helps.

The print carriage may get stuck on either side or in the middle of the printer. The Carriage Jam: Open Door, clear carriage jam, and then press OK to continue error message may display on the front panel of the all-in-one.

Solution
The print carriage is the device which contains the print head and moves left to right during printing.
Figure 1: Carriage Assembly

To resolve this issue, follow the steps below in the order presented.

Step one: Print a Self Test

Follow the steps below:
1. Press the Setup button.
2. Select Print Report and press OK .
3. The self-test page should print. If it prints a test page, there is no need to follow the remaining steps, as the error message may be false. Make sure the printer now prints from the computer (if installed on one). If it does not print, proceed to the step two.

Step two: Clear the paper path

Follow the steps below to clear the printer of any jammed paper and reset the printer.
1. Leave the printer on and then disconnect the power cable and the USB or Ethernet cable from the back of the printer. Do not reconnect them until instructed to later.

NOTE: Make sure the printer is on before disconnecting the power cord. Failure to disconnect the power cord from the rear of the unit can cause damage when removing jammed paper.

2. Open the top access door.

Figure 2: Opening the top access door

3. Make note of where the carriage is stuck and look for jammed paper. A paper jam can cause the error message and the carriage stall. Some paper may be jammed in different locations than those shown in the photos below.

Figure 3: Paper jammed on the left side

Figure 4: Top view of paper jammed on the left side

Figure 5: Paper jammed on the right side

Figure 6: Top view of paper jammed on the right side

NOTE: Do not use any tools or other devices to remove jammed paper. Always use caution when removing jammed paper from inside the unit.

If the carriage is stuck on the right side:
a. Check for any paper or object that may be restricting the carriage.
b. Move carriage all the way to the left side.
c. Check the paper path all the way to the right side and remove any paper still in the printer.

If the carriage is stuck on the left side:
d. Check for any paper or object that may be restricting the carriage.
e. Move carriage all the way to the right side.
f. Check the paper path all the way to the left side and remove any paper still in the printer.

If the carriage is stuck in the middle:
g. Check for any paper or object that may be restricting the carriage.
h. Move carriage all the way to the left side.
i. Check the paper path all the way to the right side and remove any paper still in the printer.
j. Move carriage all the way to the right side.
k. Check the paper path all the way to the left side and remove any paper still in the printer.
4. Remove the rear access door or duplexer (if installed) from the back of the printer.
5. Check for and remove any paper still in the printer.
6. Replace the rear access door, and close the top access door.
7. Reconnect only the power cable. If the printer does not automatically turn on, press the Power button.

NOTE: The printer may go through a warm-up period of up to two minutes. Lights may flash and the carriage may move. Wait until this warm-up period is complete before going to the next step.

8. If the Power light is on steady, print a self-test page as done in Step one.

If the Power light is not on steady and the carriage is still in a stalled position, proceed to the next step.

Step three: Plug the printer directly into a wall outlet

Verify that the printer is properly connected to a suitable power source by following the instructions below.
1. Verify that the computer and the printer have a three-prong power plug.
2. Remove the printer cable from any power strips or surge suppressors, and plug it directly into a grounded (three-prong) wall outlet.
3. Try the print job again to see if this step resolved the issue.

NOTE: If the printer prints when plugged directly into a wall outlet while disconnected from any power strips or surge suppressors, the power strip or surge suppressor may not be allowing sufficient voltage to reach the product.

4. If this did not resolve the issue, proceed to the next step.

Step four: Service the product

If you have completed all of the steps listed above and are still experiencing a problem, service your product.hope this helps

Do not continue this way, you are sure to ruin your paper sensor or the like. Most probably you have a paper jam inside near the carriage or roller. Open at front, check inside for paper jam.
