(15) How to replace the perforation Lower Blade
① As the lower blades of the perforator repeatedly cut the paper, the paper finish condition
degrades.
② If this is the case, shift the lower blade position slightly.
③ If the lower blades cannot be shifted any more, it is necessary to replace them.
④ Remove the perforator by reversing the procedure described in (12) (How to attach the
perforator).
⑤ Shift the perforator lock lever to the right and raise the upper blades.
⑥ Remove the hexagon socket set screws from the lower blades.
⑦ Remove two screws, followed by the cartridge bearing lid.
⑧ Remove the ball bearing, plain washer, and spring, and pull out the lower blades.
⑨ Replace them with new ones and assemble by reversing the removal procedure.
Caution
Avoid contacting the cutting edge of the
perforating blade. Otherwise, injury could occur.
