8.1.11 PAPER MISFEED – DUPLEX PRINTING (GUIDE PLATE)
SERVICE CENTER CALL RESPONSE
A jam occurred between sensors during duplex
printing.
When paper is sent to the duplex unit during
duplex printing, the trailing edge sensor detected
the trailing edge of the paper but the registration
sensor could not detect the leading edge of the
paper.
Ask the operator to try the following procedures to
remove and prevent paper transport jams during
duplex printing. Also, check inside the duplex unit
or printer for paper. If you find paper inside the
duplex unit or printer, remove it, and then press
the [Paper Feed] key.
(1) Check the type and condition of the paper,
then do the following procedures.

1-1 If the paper is thick (105 g/m or more), feed
the paper manually for one-sided printing.
1-2 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.
1-3 Check the paper and if it is coated, make sure
it meets specifications for coated paper. Use
only coated paper that is recommended for
use with this printer.
1-4 Curl can develop if paper remains unused and
loaded in the paper cassette for a long period.
Remove the curled or wrinkled paper.
(2) Disconnect the duplex unit and check the
reverse guide to make sure that reverse guide
is closed on both ends. If open, lock the
reverse guide on both ends.
