Subject: DF-600 / DF-610 and PH-3A/3C change for KM-7530
Model:
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
improve tolerance against clutch locking due to the unsuccessful recovery of spring,

CHANGE 3.: Measures for the erroneous operation
‘MAIN PCB’ has been changed to prevent PI (photo interrupter) erroneous operation and to improve tolerance
due to the increase of processing number of the sheets.
New version Main PCB mentions ‘VER 3’ (REV 3).
• ‘MAIN PCB ASS'Y’: Q30 is removed and the number of relay poles has been changed from 1 to 2.
In order to secure good operation, the number of the elements (transistor) has been changed from 4 to 6.
(staple motor drive circuit is changed.)

paper is ejected to the main tray
after saddle stitching.
(DF-610 only)
When paper with centerfold is stacked, the set count should be cleared if there is
no more paper on the tray. However, if the centerfold unit is pulled out at that time
(when there is for example a paper jam), the communication between the finisher
and the centerfold unit is interrupted. Then, if the communication task restarts the
receiving buffer is cleared and ‘paper empty’ on the tray is detected. As a result,
the stack count for centerfold is cleared.
→ Software has been changed so that the counter is not cleared when there is
paper on the stack tray for centerfold, even if the centerfold unit is pulled out and
put back.
When the centerfold unit is installed, ‘main tray overflow’ is detected at 1,500
sheets. However, the main tray goes up and down at every straight ejection and
the tray detection sensor for 1,500 sheets is hereby turned on and off. Because of
this, the message ‘main tray overflow’ appears and disappears repeatedly.
→ S/W has been changed to solve this.
Phenomenon
In the main tray ejection mode, when the paper is ejected with saddle stitch and
staple, if the number of the stacked paper is increased, paper may jam at the
ejection side.
Change
Software is changed as follows.
• Count the sets of ejected paper with saddle stitch and staple to the main tray,
and give the notice of the main tray full to the copier at 50 sets count so that the
copier stops the operation.

4 Addition of Sim. 237 (= ‘Setting
the number of stacked sheets on
the main tray’)
This simulation is added for both
DF-610 and DF-600.
Presently this simulation is
supported in combination with
KM-7530 only. In future, this
simulation will be also supported
with KM-6330, KM-4530 and KM-
5530. Details will follow later.
PUNCH UNIT CONTENTS OF CHANGES
CHANGE 1.
In order to prevent the paper from twisting / bending due to the increase of peripheral speed, the number of
rotation for punch cam shaft has been increased. Additionally, in order to secure the stopping accuracy of the
cam shaft, the structure of ‘UNIT, PUNCH’ (= component part of ‘PUNCH ASS’Y’) has been changed.
• ‘SPRING, STOPPER’:
Dimensions have been slightly changed to prevent the stapling from being performed twice and for
reinforcement due to increase of the rotation numbers for punch.
• ‘SPONGE, STOPPER SUB’:
The thickness is changed from 4mm to 5 mm to reduce noise.
CHANGE 2.
The clutch has been changed to secure proper rotation of the ‘CLUTCH, PUNCH’ due to the raise in
temperature.
• ‘CLUTCH, PUNCH’: shape change
• ‘BUSHING, PUNCH CLUTCH’: newly added.
SPRING, STOPPER

Paper might jam or fall due to the paper curl around the time that 3,000 sheets of
paper are stacked without stapling.
Software has been changed so that the number of stacked sheets without stapling
is adjustable to 1,500 sheets or 3,000 sheets by simulation 237.
Sim 237: Setting [0] → Present state
Setting [1] → 1,500 sheets/1,000 sheets support
The following change is made in case of using the small size (*) paper without
stapling.
DF-610: possible to change to 1,500 sheets / 3,000 sheets
DF-600: possible to change 1,000 sheets / 2,000 sheets
* As for larger size, originally, the upper limit is 1,500 sheets or 1,000 sheets.
