DF-600: KM-4530 / DF-610: KM-4530/5530/6330/7530

Please be informed that a number of parts on the DF-610 have been changed and improved in order to use
this finisher perfectly in combination with the KM-7530. (DF-600 is also affected by these changes as some
parts are shared with the DF-610.)

Attention:

When installing the DF-610 to the KM-7530, please check if it is the new / slightly modified DF-610.
When installing the punch unit (PH-3A/PH-3C) to the KM-7530, please check if the punch unit is the new / modified type..
A distinction can be made between old and new type by a marking seal, which has been added to the outer packaging of the
new types.(see photos below.)

A round red seal is attached next to DF-610.
Note:
As for the DF-610 that supports the
KM-6330, a green seal is attached instead.

DF-610 CONTENTS OF CHANGES

CHANGE 1.: Noise reduction at paper conveying

Paper conveying noise may increase because the usage frequency of the siding drum goes up.
In order to prevent any noise, if present, the following change has been done.

• ‘RIGHT GUIDE, SUB CONVEYING’: ribs were added.

• ‘GUIDE, FEED SHIFT SUB EJECT’: shape of claw changed.

• ‘SHAFT, CONVEYING DRUM’: fixation pin for drum and gear is changed from ∅2 spring pin to ∅2.5 parallel
pin to create a more stable fixation of drum and gear. In compliance with change of pin, the size of the hole
in the shaft also needed to be changed.

• ‘SHAFT, CONVEYING DRIVE’: size of hole in the shaft has been changed.

CHANGE 2.: Improving tolerance for clutch locking

• ‘CLUTCH 33, CONVEYING’: ‘spring clutch’ has been changed to ‘electromagnetic clutch’ in order to
