- Confirm the height every time you move the equipment.
C. When installing the Finisher in the equipment, make sure that the height of the Finisher is proper. If it is not, the

Check if the Mylar attached to the exit of the Bridge Unit is deformed and obstructing the paper transport path.
Correct it if deformed.
2. Bridge Unit exit Mylar deformed
B. To keep the installation height of the Finisher stable, it is preferable that the casters are faced to the equipment
side.
A. Confirm that the Finisher is installed horizontally (the height of its front side and that of its rear side are the
same
)
.
1. Improper installation height
(Paper is not properly transported
from the equipment to the
Finisher if each height is
improper.)

a: Slide the buffer guide to the center and lubricate between the shafts of the
front buffer guide.
b: Slide the buffer guide forward or backward and lubricate between the shafts
of the rear buffer guide.
* Be sure to lift up the buffer roller before sliding the guide.
5. False operation of the entrance
sensor or the transport sensor
(An error may occur when the
entrance sensor or the transport
sensor does not perform proper
detection.)
A. Check if the wires of the entrance sensor or the transport sensor are being caught or short circuited, or any of
their connectors is disconnected.
4. False operation of the buffer
guide
(Paper jams may occur if the load
is applied to the buffer guide
during its opening or closing
movement.)
Remove the stationary tray and apply grease "Molykote EM-30L" (the size of 5 grains of rice) to the buffer guide
shaft.

3. Improper connection between
the equipment and the Hole

(Paper is not properly transported
from the equipment to the Hole
Punch Unit if they are not
connected correctly.)
When the Hole Punch Unit is installed, check if the connection point is shifted forward or backward.

7. Paper not placed properly in
the drawer
(Paper may be skewed if there is
extra gap between the paper and
the side wall in the drawer and
thus may cause a jam on the
Finisher transport path.)
Be sure to lock the side wall.
Operation check of the transport sensor actuator: Rotate the shaft slowly. If the actuator is not rotated together, its
o
p
eration is normal.
6. False operation of the paper
exit guide
(An error may occur when the
paper exit guide is not operating
properly because paper may
remain on the finishing tray or not
exit properly during sort or
stapling exit.)
Replace SPG-SFFD-SUPT-SF (6LB090140) if the paper exit guide is not operating properly.

5. False operation of the entrance
sensor or the transport sensor
(An error may occur when the
entrance sensor or the transport
sensor does not perform proper
detection.)
B. Check if the actuators of the entrance sensor and the transport sensor are operating smoothly. If they are not,
remove the actuator and check if there is any paper dust or foreign matter between the shaft and the hole. Clean if
there is.

When replacing, be sure not to scratch the shaft (ASYB-SFT-EXT-RLR-DRV-

B. Check if the gear teeth of GEAR-IDLER-EXT-BUF, GEAR1-EXT-RLR-BUF and GEAR2-EXT-RLR-BUF mesh
correctly. If any of them does not mesh correctly, replace ASYB-SFT-EXT-RLR-DRV-BUF, ASYS-LVR-E-RLR-

2. Stationary tray opening/closing
switch actuator deformed
(A cover-open error occurs if the
actuator is deformed because the
stationary tray opening/closing
switch cannot be turned and
performs false detection.)
Replace PLT-OPEN-SW-BUF if the actuator is deformed.
Close the stationary tray securely if it is open.1. Stationary tray left open
(A cover-open error occurs if the
stationary tray is left open
because the stationary tray
opening/closing switch performs
false detection during operation.)
Replace HNDL-DOOR if the actuator is deformed or damaged.3. Front cover switch actuator
deformed (MJ-1101)
(A cover-open error occurs if the
actuator is deformed because the
front cover switch cannot be
turned and it performs false
detection.)

Turn the power OFF. Then check the gap between rollers on the buffer roller guide and the buffer tray while the
buffer roller is left lowered. If the gap does not reach 0.3 mm, replace the buffer roller guides (LVR-E-RLR-BUF)
on both front and rear sides.
3. Improper roller gap on the
buffer roller guide and buffer tray
2. Catching pad link arm
deformed, damaged or removed
(Paper is not aligned properly
because the link arm of the
catching pad is deformed,
damaged or removed.)
Check the gap within the range 7 mm from the edge of the buffer roller guide.
- When more than one
sheet of paper is
loaded on the buffer
tray, the first sheet is
pushed out of the tray
by the second sheet.
- When more than one
sheet of paper is
loaded on the buffer
tray, the leading edge
of the second sheet is
caught and thus a
paper jam occurs.
- When paper is
transported from the
buffer tray to the
finishing tray, the
paper is run on the
front or rear alignment
plate.
- When paper is
loaded on the finishing
tray, the front and rear
alignment plates
excessibly push the
paper.
- When paper is
transported from the
finishing tray to the
movable tray, the
paper exit guide
catches the paper and
thus a motor error
occurs because the
paper cannot exit.
Check if the catching pad in the Finisher paper exit section is properly attached. If its link arm is deformed,
damaged or removed, replace ARM-SOL-ALIGN (6LB100080).
Check if the catching pad in the Finisher paper exit section is properly attached. Replace it if it is deformed or

4. Improper spacing on the edge
section of the buffer roller guide
and the buffer tray upper section
- When more than one
sheet of paper is
loaded on the buffer
tray, the first sheet is
pushed out of the tray
by the second sheet.
- When more than one
sheet of paper is
loaded on the buffer
tray, the leading edge
of the second sheet is
caught and thus a
paper jam occurs.
- When paper is
transported from the
buffer tray to the
finishing tray, the
paper is run on the
front or rear alignment
plate.
- When paper is
loaded on the finishing
tray, the front and rear
alignment plates
excessibly push the
paper.
- When paper is
transported from the
finishing tray to the
movable tray, the
paper exit guide
catches the paper and
thus a motor error
occurs because the
paper cannot exit.
Turn the power OFF and pull the plunger of the buffer roller lift solenoid by hand. Then check the spacing on the
edge section of the buffer roller guide and the buffer tray upper section while the buffer roller is lifted up. If the
edge section of the buffer roller guide is not lower than the buffer tray upper section, replace STAY-BUFFER.
- If the joint surfaces of the stationary tray and the rear lower cover (or the
control panel unit) are shifted 4 mm or more, the motor bracket may be
deformed.
- Do not hold the stationary tray when unpacking.
5. Motor bracket deformed
(The bracket of the buffer tray
guide motor or the buffer roller
drive motor is deformed and thus
drive is not transmitted.)
If the buffer tray guide motor bracket (HLDR-TRAY-BUF) or the buffer roller drive motor bracket (HLDR-MOTR-
BUFFER) is deformed, replace it.

8. Stack transport motor belt out

If the stack transport motor belt is loose, retighten it, or replace the motor bracket (BRKT-MOTR-SF) to retighten
the belt.
7. Improper installation of
alignment plates
6. STAY-BUFFER deformed Remove the bracket of the buffer roller lift solenoid. Then check that STAY-BUFFER is not deformed using a
scale or other straight tool. Replace it if it is deformed.
If the front or rear alignment plate is removed or its installation is improper, reinstall it. (The alignment plates must
not be risen even if they are tilted to the right or left.)
