Epson EPL-N2750 Quick Reference Manual page 9

Note:
If the paper jam is in the Large Capacity Paper Unit, you
may find it easier to remove the jammed paper if you open
both the cover and the cassette.
When the paper jam is cleared completely, the jammed
page's print data is automatically reprinted.
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.
