MX-FNX2/AR-PN1/MX-RBX1  DISASSEMBLY AND ASSEMBLY  6 – 4

8)

Insert a pin [18] with a diameter of approximately 2 mm 
(use of a 2 mm Allen wrench is recommended) in the round
hole to secure the gear.

9)

Turn the gear [19] to align the round hole in the staple clincher
cam with the round hole [20] at the back.

10) Insert a pin [21] with a diameter of approximately 2 mm (use of

a 2 mm Allen wrench is recommended) in the round hole to
secure the gear.

11) With the gears and cam fixed, install the timing belt [22] on

gears [23] and  [24].

12) Mount the staple position check gear [27] so that the blue mark

[25] on the staple position check gear is aligned with the round
hole [26] in the frame.

The position where the blue mark is aligned with the round
hole is the home position for stapling. If the staple jam cancel
dial is turned for some reason, the home position deviates,
making it impossible to remove the stapler cartridge.  If such a
case, the gear can be returned to the home position by check-
ing blue mark position.  Therefore, it is necessary to mount the
gear at the correct position.

13) Remove the pin securing the gear to the cam.
14) Assemble the spring [28], spacer [29], staple jam releasing

gear [30], timing belt [31], and relay gear [32] and secure them
with the E-ring [33].

If the gears at the front of the saddle unit or the paper fold rollers in
the sale unit are replaced or removed for some reason, adjust the
gear phase following the procedure described below.
1)

The paper fold rollers [1] and saddle cam [2] must be posi-
tioned as shown below.
