Measures
The actuator for the PF paper
feed sensor is caught. Also, if
it comes off, reattach the
actuator and its release
spring.
When the sensor surface or
photoreceptor black felt is
dirty by paper dust, etc.,
clean them.
Check the sensor operation
by executing U031 and U241,
and clean or replace the sen-
sor if it does not operate
properly.
Measures
When there is no margin from
the paper leading edge to
4.0mm(+1.5/-0.0mm), and,
when there is no check line
(fuser jam) on 20mm(+/-
1mm) from the paper leading
edge of the test pattern that is
output in U034,adjust the
leading margin at U402.
Relocate the paper width
guides or the MP paper width
guides along the paper size
to properly detect the paper
size.
If the media type is not
matched to the actual paper
weight (the paper jam occurs
due to the paper separation
failure), set the media type at
[System Menu/Counter] key
> [Common Settings] > "Org./
Paper Set.".
