Measures
Adjust the height of the DP

Check if the document pro-
cessor is securely closed. If it
cannot be closed due to the
DP frame deformation,
replace the document pro-
cessor.
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-
nal within the specifications.
Remove the foreign objects
on the original. If it is not pos-
sible to remove the foreign
objects completely, remove
the original.
Turn the DP exit sensor on
and off manually and check
the indication at U244 [Eject].
If the DP exit sensor does not
properly operate, clean and
reattach it and reinsert the
connector. If not repaired,
replace it.
Execute U243 [Conv Motor].
If the DP conveying motor
does not properly operate,
reattach it and reinsert the
connector. If not repaired,
replace it.
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.
