Cannot close the Process Unit
[Location]
Process Unit
[Cause]
If the main power switch is turned OFF just after the copy operation (approx. within 5
seconds) and the Process Unit is opened, the Laser Shutter May not be closed.
As a result, the rear side of Process Unit and the Laser Shutter interfere each other when the
Unit is closed and the Process Unit cannot be installed to the host machine.
[Occurrence Condition]
If the main power switch is turned OFF just after the copy operation (approx. within 5
seconds) or if the power plug is disconnected without turning OFF the main power switch.
[Field Remedy]
Process Unit can be installed to the host machine by strongly pushing it.
However, if the Unit is installed to the host machine with brute force, it may damage other
parts. Thus, be sure to follow the below operation procedure.
1) Turn OFF/ON the main power switch. (Laser Shutter is closed automatically.)
2) While the Process Unit remains pulled out, make sure that the Laser Shutter is surely
closed. At this time, do not put your hands inside the machine.
3) Turn OFF the main power switch and install the Process Unit to the host machine.

Productivity decrease at stack delivery in thin paper (52g/m2 ~
63g/m2) mode < Staple Finisher C1/Saddle Stitch Finisher C1>
[Location]
Process Tray on the Staple Finisher C1/Saddle Stitch Finisher C1
[Cause]
When the thin paper (52g/m2 to 63g/m2) is selected and the paper stack is delivered from
the corresponding finisher, electrostatic is generated under the low humidity environment
because the paper is fractioned in the Process Tray causing paper attraction. As a result,
alignment failure may occur.
To avoid this, the electro static is prevented from being generated by decelerating the feed
speed in case of foregoing condition.
[Occurrence condition]
This paper (52g/m2 to 63g/m2) is selected and the paper stack is delivered from the
corresponding finisher.
[Field Remedy]
Change the paper selection to plain paper 1 (64g/m2 ~ 81g/m2) and deliver the paper stack.
Approx. 19% of productivity can be enhanced (in the following condition).
Condition: A4 paper and 10 sheets stack delivery (1-point staple)
[Note at operation]
Feed speed is enhanced when the plain paper 1 (64g/m2 ~ 81g/m2) is specified for paper
selection.
However, the possibility to generate the electrostatic is also increased when the feed speed is
enhanced and it may cause the alignment failure.
If such a case, change the paper selection to thin paper (52g/m2 ~ 63g/m2).
