Epson 3260 - Manual (Page 81)

When you send data or press the FF button, the push tractor does
not feed the paper.
Check that the paper-release lever is in the raised, continuous-
paper position
The paper has come off the push tractor. Reattach the paper to
the push tractor.
Paper feeding from the push tractor is crooked or the paper jams.
The position of your paper supply may be preventing it from
feeding straight. Make sure the paper supply is not obstructed
by a cable or some other object.
Make sure that your paper supply is positioned within 1 meter
(3 feet) of the printer.
Check that the holes on the sides of the paper are aligned with
each other. Also, make sure the sprocket units are locked and
their covers are closed.
Check that the paper-thickness lever is set correctly for the
paper you are using. See “Adjusting the paper-thickness lever”
in Chapter 2.
Check that the paper size and thickness are within the
specified range. See the paper specifications in the Appendix.
The paper fed from the push tractor does not eject properly.
The page may be too long. Tear off the fresh supply of paper
and eject the page from the printer. Use only paper that is
within the specified length range described in the Appendix.
