Epson LX-810 User Manual page 211

Problem
You tried to
manually insert a
single sheet, but
instead paper was
fed from the cut
sheet feeder's bin.
One page of
printing has spread
to two pages.
Solution
The single sheet may have been inserted in
the wrong place. Check the position of the
paper and try again. Refer to
Your document may be more than one
page long. If so, the first page can be fed
manually, but subsequent pages will feed
from the cut sheet feeder bin. If you need
to print more than one page using manual
feeding, pull the paper set lever forward.
The page length setting may be wrong.
Run a self test in CSF mode. The printer
will automatically measure the paper
loaded and set the correct page length.
Refer to 5-9.
