To change the driver, loosen the
knurled screw and pull the driver from
the spigot which is sprung and on
bearings, and pull it upwards out of the
stapler head guide. To install, guide the
driver in from above and hang it on the
spigot.
Then tighten the knurled screw. When
changing the driver, care is to be taken
that the engraving “26” on the upper
end of the driver shows towards the
operator. Normally Foldnak stapling
folding machines are delivered with
ring drivers (item no. 2932619) which
are suitable for stapling with ring
staples or staples. Instead of the ring
driver, a flat driver (item no. 2932616)
can be used for thick layers.
8.3 Stapler
head
care
and
malfunctions
Damaged staples must be removed from
the stapler head staple channel. For this,
pull back the staple slide (fig004, 26)
until it engages, then loosen both
knurled screws (fig004, 24) and swing
the straps (fig004, 27) towards the
bottom.
The stapler head can be pulled off after
the contact wire has been pulled off.
The stapler head front plate and the
magazine are to be cleaned of staple
remnants as well as the front plate still
in the machine.
Then replace the stapler head and
tighten the knurled screws (24). Staple
remnants in the guide channel can lead
to driver breakage. Please, therefore,
thoroughly clean the guide channel
every time stapling is unsuccessful.
Very thinly grease the driver above the
stapler head after approximately ever
5,000 staplings.
Clean the stapler head regularly,
otherwise faulty operation could occur
because of dirt.
Should there not be any staples in the
paper although the magazine is full:
Check whether the staple slide is bent
forward due to accidentally being
allowed to spring forward. If this is the
case then carefuly file off these burrs so
that the staple slide can again push
completely forwards into the stapler
head.
8.4 Cleaning rollers
With use, printer’s ink can collect on
the rollers. This can reduce the rollers’
grip. For this reason the rollers must be
cleaned when needed. A cleaning agent
can be used for this, such as is used for
folding machines or pressure rollers.
