This message indicates that there may be a paper jam inside the
cover of the Duplex Unit, which is also known as cover D.
Follow these steps to clear paper jammed inside the cover of the
Duplex Unit:
1. Open cover D.
Note:
Because the toner on the paper inside the printer may not have been
fixed on the page, toner may come off on your hands when you
remove the paper. If you spill toner on your clothing, rinse it off with
cold water. Using hot water may leave a permanent stain.
