Uper Duplex not holding card in place

Is there any message on the operator panel when the jam occurs? Where in the paper path does the jam occur? There are diagnostic tests in the printer but those are best left to an authorized service center.

Metal tab on right side of copier is bent and correctly touching the duplex unit interlock switch. Open the duplexer and notice the metal tab stick out. Put back to a 90 degree angle.

Open the duplex module cover at the back of the printer (1).
Release any cards stuck in the module (2). Make sure that the duplex
mechanism can move freely in the direction shown

It means a card is jammed in the top back part of the printer. You may need to open up the back hatch to pull out the card.

Every time you open the printer, it advances CMYK panel 01 to position the print head.This can cause loss of ribbon. Avoid opening the printer to the maximum you canoptimize your prints.

Your duplex is the big box on the right side of the machine push the back side shut against the machine and try again

Sounds like either the thermocouple or the heater went out. Was this the error code?

OP-01604 Thermocouple problem in L1 laminator

The comments in the service manual states:
- Check the thermocouple wire for damage.
- If the thermocouple was recently replaced, verify that it is not installed backwards
- Verify that the thermocouple connector is not unplugged or plugged in backwards

I would probably order a replacement part, call in your local DataCard service representitive or send it to DataCard for repair.

Hi Bret! Since this is a brand new printer, I would advise calling Lexmark. I'm afraid that you may void your warranty if you do much more at this point except for going back through the steps to make sure the duplexer was installed correctly.
1. Power off the printer and unplug the power cord from the wall outlet
2. Push the release button, and gently lower the front door.
3. Release the green tabs and lift up the image transfer belt.
4. Remove the cover over the duplex connector.
5, Remove the duplex option from the packaging. Carefully install the option into the printer, under the image transfer unit. NOTE: Make sure to line up the arrows on the duplex option with the arrows on the printer. Make sure the duplex option locks into position.
6. Lower the image transfer belt back into position. Make sure the belt locks into position.
7. Close the front cover.
8. Plug the printer back in, then power the printer on.
9. Try printing a few pages to confirm that the duplex option is securely installed. Then select the duplex option in the software and print a few double-sided pages to confirm that the duplex option is working.
The following link will take you to the instructions for enabling the duplex option in the software.

If the above does't work, I would strongly suggest contacting Lexmark for further help.
