1. OUTLINE OF EACH MECHANISM AND ADJUSTMENTS
Adjustments
(1) Adjusting the tension of the timing belt
Adjust the position of the pinch roller unit so that the

Precautions on replacing the flat belt
Replace taking note of the rotating direction of the flat belt. (Arrow at the back of the flat belt)
Replace the flat belt in pairs.
1-2. Back Jogger Mechanism
The base moves forward and backward by changing the rotating movements of the stepping motor to linear
movements.
The pusher attached to the base pushes in the paper.
Adjustments
(1) Adjusting the position of the collar 05-20-12
Adjust the position of the collar 05-20-12 so that the
lever and link become parallel.
1-1. Conveyance Mechanism (Entrance)
Paper is conveyed by the flat belt.

1-3. Side Jogger Mechanism
The timing belt moves forward and backward from the rotating movements of the stepping motor.
The jog plate pushes in the paper.
Adjustments
(1) Fixing the STS belt and bracket
With the bracket touches against the two sides, fix the plate and STS belt.
(2) Adjusting the tension of the STS belt
Adjust the position of the pulley unit so that the belt slacks by 10 mm when a pressure of 0.98 N (100 gf) is
applied.
(3) Adjusting the parallelity of the jog plate
Adjust the distance (difference between A and A'
and that between B and B') between the groove of
the guide plate and jog plate to below 0.5 mm.

1-4. Stapler/Clincher Mechanism
The stapler unit staples the paper while the crank shaft makes one round by the DC motor, and at the same time, the
cam drives the clincher to bend the staple flat.
Adjustments
(1) Adjusting the height of the clincher
When the cam is at the top dead point, adjust so that the upper surface of the clinch plate and tip of the clincher
are of the same level.

(2) Adjusting the front and back positions of the stapler unit
Adjust the position at which staples come out of the stapler unit to the groove of the clincher.
qSet the stapler unit with the staple cartridge removed and clincher at the 140 (5" 1/2) position of the indication
label.
wRotate the crank shaft to the stapling position (bottom dead point).
eLoosen the M4 nut and M6 nut.
rRotate the position adjusting screw (M4 capscrew bolt), and adjust the position of the staple guide so that the
position at which staples come out of the stapler unit (small projection) coincides with the groove of the
clincher.
tAfter completing the adjustment, tighten the M4 nut and M6 nut.

(3) Adjusting the pushing amount of the stapler
unit
Set to the stapling position (bottom dead point) and
check the pushing amount of the stapler unit by
inserting the tool.
qRemove the M3 screws, and remove the staple
remaining detection sensor (upper side).
wSet the stapler unit with the staple cartridge removed and clincher at the 140 (5" 1/2) position of the indication
label.
eLoosen the M8 nut and M4 bolt.
rSet the stapling state (bottom dead point), and check the pushing amount of the stapler unit using the tool.
As the thickness of the tool differs between the two ends, if the thinner end fits the space while the thicker end
does not, it means it has been adjusted.
∗If both ends of the tool fit the space, rotate the adjusting screw (M4 capscrew bolt) to the left.
If both ends of the tool do not fit the space, rotate the adjusting screw to the right.
tAfter adjusting, tighten the M8 nut and M4 bolt, and attach the staple remaining detection sensor (upper side)
removed at q.

(4) Adjusting the position of the stapler home
sensor
When the rod is at the top dead point, adjust the PH
angle to the position where it blocks the optical axis
of the photointerrupter by 2 to 3 mm.

(5) Adjusting the position of the stopper
To prevent mis-stapling (no staples are stapled),
adjust the stopper position so that the stapler unit
does not shake at the standby position (top dead
point).
qLoosen the screw.
wLower the stapler unit.
eLower the stopper, and fix it when it touches the
stapler.
(Fix the left and right sides at the same height.)
NOTE : If this adjustment is not complete, staples
will not be conveyed inside the stapler
unit and therefore no staples will be
stapled.

(6) Checking stapling
Set the stapler unit and clincher at the 40 (1" 5/8) position of the indication label, staple, and check the stapled
condition.
