(Calibration).
Reattach the DP multi-feed-
ing sensor (emitter) or the DP
multi-feeding sensor
(receiver) and reinsert the
connector. If not repaired,
replace the sensor.
Reconnect all the connector
to the DP main PWB. Then,
fix or replace the wires if they
are pinched by other part or if
they have any damage.
When the issue is not
resolved, replace the DP
main PWB.
Measures
Remove the folded original.
Fix or replace paper. If it is
difficult to replace, relocate
the leading edge with the
trailing edge of the paper to
feed or turn over the paper,
and reinstall it.
Explain users to use the origi-
