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.

your sensor flag in the back is broken or missing

Try changing the photoconductor kit
