20 Most Recent Lexmark X342n All-In-One Laser Printer Questions & Answers


Quoting from support.lexmark.com above:


Error: "936 Main Drive Motor"; Error: "936 Transport Motor"; Error: "937 Main Drive Motor"; Error: "937 Transport Motor"


The 936 and 937 error codes indicate that the printer thinks there is a problem with the main drive motor.


  1. If your printer is posting one of these errors, turn it off and let it sit powered off for at least a minute.
  2. While the printer is off, open all of the doors and covers on the printer. Also remove the toner cartridge. Make sure there is no paper jammed in the printer. Pay close attention to the area where the toner cartridge sits. The main motor is located just to the left of the toner cartridge.
  3. If nothing appears to be wrong with the inside of the printer, reinstall the toner cartridge and close all the doors and covers. Now power the printer back on. If the error does not return, try printing again.
  4. If the error does not return when you print, continue using the printer. If the error does not return after a few days, this may have been an isolated incident and the printer should be fine.

If you have snapped the lid switch or male end to sensor, you may have to jump out the door switch.

If not, see the attached link for information

This means that the photoconductor has reached the end of life; on other printers, this is called the drum. It transfers the toner onto the page during printing so that it will fuse to the paper. The replacement is $70 from Lexmark: http://www.lexmark.com/US/en/view/Ink/Toner%20&%20Supplies/X340,-X342-Photoconductor-Kit/catId=cat170003-category&prodId=3599-product . The replacement should last about 30000 pages.

To replace the unit after you get a replacement, open the front cover and pull out the print cartridge assembly by the handle. Put the assembly on a flat surface. Remove the toner cartridge by pressing the button on the assembly and pulling on the handle. Open the new photoconductor kit and snap the toner cartridge into place on it. Then slide the new assembly into the printer. The steps are shown here: http://support.lexmark.com/index?page=answerlink&userlocale=en_US&segment=SUPPORT&locale=en&url=http%3A%2F%2Fsupport.lexmark.com%2Findex%3Fpage%3Dcontent%26id%3DSO4365%26actp%3Dsearch%26viewlocale%3Den_US&productCode=&answerid=16777217&searchid=1397780403561 .

After installing this, you need to reset the photoconductor counter.
With the printer on, open the front cover and press and hold Stop for 5+ seconds. When you see Resetting PC Counter release the Stop button. Close the front cover when prompted to do so.

If this doesn't clear the error, try powering off the printer for 10 seconds. Otherwise, try unplugging the printer for a minute to reset the internal memory. If the unit still doesn't reset the counter, it may need service. Contact Lexmark.

I hope this helps.
