ENUS31242What you will see
The paper jams when you try to print on both the front and back sides of the page (duplex printing). Each time, the printer will display a 233 type numeric error.
Recommended actions
The first action is to locate and remove the jammed paper.
NOTE: There may be more than one page jammed in the printer. Make sure to check/clear the entire paper path.
| Step | Action | Image |
| 1 | Remove the standard paper tray (Tray 1) from the printer. | |
| 2 | Look into the area where the paper tray was and locate a green tab. Push down on the green tab; this should lower a green plastic guide. | |
| 3 | Look for any jammed sheets of paper stuck behind the guide. If there is any paper jammed in this area, carefully remove it. | |
| 4 | Open the front door. | |
| 5 | Go to the back of the printer and open the rear access door. | |
| 6 | Look for any jammed sheets of paper. If there is any paper jammed in this area, carefully remove it. | |
| 7 | Close the rear door. |
| 8 | Close the front door. |
| 9 | Reinsert the paper tray. |
| 10 | Press the button to continue or try printing again. If paper continues to jam, see the additional suggestions below. |
Additional suggestions
- Make sure you are loading the paper into the tray correctly. The side and rear paper guides on the tray should be resting lightly against the edges of the paper but not putting pressure on the paper.
- Make sure the standard paper tray (Tray 1) is not overloaded.
- Make sure the rear door is closed completely and stays fully latched.
- If the paper is stopping above Tray 1 (behind the duplex guide mentioned in step 2 in the table above), check the position of the green plastic duplex guide. If this guide is not properly seated, repeated paper jams can occur here. To check the position of the guide, you will need to follow the steps in the table below.
| Step | Action |
| 1 | Power off the printer. |
| 2 | Open the front cover and remove the print unit assembly (toner cartridge and photoconductor). |
| 3 | Remove the standard paper tray (Tray 1). |
| 4 | Carefully place the printer on its side. |
| 5 | See the area highlighted in the photo below. Make sure the guide is snapped in all the way. If not, try to snap the guide back into place. |
| 6 | If you are able to snap the guide back into place, set the printer back on its base. Reinstall the paper tray and the print unit assembly. Power on the printer and try printing again. |
| 7 | If the issue persists after you have tried all of these suggestions, service may be required to correct the issue. For assistance in setting up service, please contact Lexmark Technical Support or a local authorized service provider. |
