engagement of the Move Paper Guide A/B, Stopper 2, and Rotation Paper, resulting in
rotation failure of the stapler (F1-87). To prevent this problem from occurring, grease is
applied to each move paper guide and to the stopper 2.
The first three measures already reported are shown below for your reference.
Please take the necessary measure depending on the situation.
[First Corrective Action: T/R No. ARE-381-4]
When the staple cartridge was changed, stapler rotation could go wrong by, for example,
misoperation (F1-87). To prevent this, we changed the shape of the ST rotation plate and
added a ST lock plate A.
To improve the situation where F1-87 is indicated due to the incorrect rotation of Stapler,
the retry operation to correct the trouble was changed.
(1) In case that the Stapler does not correctly reach to the stapling position within the
Stapler is returned to the home position so that the Stapler moves to the correct stapling
position and it is rotated again (with three retry).
canceled in retry, the period of the jam timer is over during the job, so not F1-87 but the
Paper Jam is indicated.
To prevent the malfunction (F1-87) of the stapler from occurring due to the movable PG SP
coming off, the shape of the hook of movable PG SP was changed. (The length of the left
hook is increased by 8mm, and the length of the right hook is reduced by 1mm.) Also,
please note that the shorter hook of the movable PG SP should be hooked to the movable
PG B/A (-28/29) and the longer hook should be hooked to the alignment tray (-18).
