(2) Adjusting the Stapler Phase
When the gears or timing belt at the front of the stapler is replaced
or removed for some reason, the staple shooting timing of the

of the staple clincher (upper unit of the stapler). Adjust the stapler
phase following the procedure described below.

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
