Decal - Paper Set Direction
The finisher stacking ability depends on the paper load orientation (face-up or face-down).
For some paper brands, face-up produces better stacking and for other brands, face down
is better. The above decal instructs customers on loading paper in order to prevent
unnecessary service calls. Therefore, please use this decal for operator training.

SYMPTOM
The end fence may detach due to vibration during transport.
CAUSE
The diameter of the holes in the paper guide fence for inserting the end fence was slightly
too large (i.e. Knob Screw with Rubber Tube). This is a side effect from the previous
modification (MB No.004).
SOLUTION
Final countermeasure on the production line
The diameter of the holes in the paper guide fence for inserting the end fence has been
decreased from 5.5 mm to 4.5 mm. Please refer to MB No. 006.
Temporary countermeasure on the production line
1.5 mm
Rubber ring
An extra rubber ring (1.5 mm) has been attached to the end fence to prevent it from
dropping. This rubber ring is made by cutting the Rubber Tube (B3032788) in the
production line to a thickness of 1.5 mm.

Note: When the new paper guide fence (B3032789: MB No.006) is installed in machines
with the extra rubber ring, it is not necessary to remove the rubber ring from the end fence.
Note:
We have applied the temporary solution at the factory from the same cut-in serial numbers
listed in MB No.004, except for the machines listed below. These units have already been
shipped and do not contain the countermeasures. However we estimate the occurrence
rate to be very low. Please reattach the end fence if it has come off during transport.
