1-2 Check to see if paper printed on one side is
being used. Paper printed on one side has a
tendency to double-feed. If the double-feeding
persists, replace with other paper.
1-3 Do not use curled (less than 2 mm) or
wrinkled paper, especially when printing on
both sides of postcards. If the curl or wrinkling
cannot be removed before printing, replace
with new paper.
1-4 Check the paper and if it is coated, make sure
it meets specifications for coated paper.
Replace with paper that is approved for use
with this printer.

loaded in the paper cassette for a long period.
Remove the curled or wrinkled paper.

Feed roller slippage.
Curled or wrinkled paper has jammed.
Not closed after a jam was removed.

locks of the reverse guide on the left and right side
(if both are not locked correctly) can cause the
paper to skew, preventing the paper from feeding.
Not closed after a jam was removed.
No force applied to the transport roller, so there
was insufficient power to feed the paper.
