Conveyance controls can be roughly divided into the following 2 patterns:
A. Pattern 1: Normal conveyance control
• While the paper is nipped to both t he main body’s fixing roller and the FNS conveyance roller, the
M701 (FNS conveyan ce motor) opera tes at the speed of 230 mm/s accor ding to the mai n body line
speed. When the paper passes through the fixing roller, the M701 operates at the speed of 600 mm/s.

SD701 (Roller releas e solenoid) i s turned on to r elease the nip of the FNS conv eyance rolle r for the
increased productivity of sorting, grouping and stapling.

paper exit opening.
If the shutter opens whi le the tray is g oin g up or d own, the MS 702 (Shu tter s wi tch ) is tur ne d o n to sh ut o ff

ALIGNMENT SECTION
3.2 Operation
3.2.1 Paper alignment control
Paper stacked by the paper exit roller /A is aligned by the alignment plates. The alignment plates provided
in front and rear, one for each, are driven independentl y by the M704 (Align ment motor /F) and the M703
(Alignment motor /R). For straight al ignment of the sorting, grou ping, and stapling oper ation, the paper
moves symmetrically in front and in rear, and is aligned at the center by the alignment plates and it moves
asymmetrically while in the shift mode.
The home positions of the ali gnment pl ates are de tected by the PS709 (Al ignmen t HP sensor /R) and the
PS710 (Alignment HP sens or /F).
A. Straight alignment operation
Small size paper such a s 5.5 x 8.5R, A5R or B5R is stacke d and aligned to prevent the p aper from
having uneven edge after being exited.
II UNIT EXPLANATION
During the paper exi t, the alignment plate /F and the alignment plat e /R move symmet rically in front
and in rear based on the center of the alignme nt sect ion with al ternatio ns of ali gnment an d alignm ent
release. Aligned papers are exited for every 5 sheets.

4.2.1 Stapler control
The stapler unit is d riv en th rough the timing belt by the M 705 ( Sta ple r mov em ent moto r). A c co rd ing to t he
form of the rail, the stapler unit can turn round at either end of the rail for oblique stapling.

(the position varies depending on the paper size)
A. Stapler movement control
The stapler is normally on s tandby at th e ho me positi on where t he PS7 08 (Stap ler un it HP sen sor) i s
turned on.
According to the s tapling selection from the copier, the M705 (Stapler m ovement motor) moves the
stapler to the position corresponding to the paper size for stapling operation. After completion of printing, the M705 moves th e stapler to the home positio n. The control of the timing for turn ing off the
M705 is made by the number of drive steps after the PS708 is turned off.

II UNIT EXPLANATION
(1) For 1 position staple
After completion of the al ignme nt oper ation of the l ast pap er, the M707 (Pressure motor ) is tur ned on
to press the paper with the paper exit roller /A. Then, the M708 (Stapler mo tor) is turned on for stapling.
For continuous staplin g, the M70 5 (Stap ler mov ement mo tor) does not mov e and the st apler r emain s
as it was, waiting for the next stapling.
(2) For 2 position staples
After the M705 (Stapler movement mot or) moves to the speci fied position from the fir st stapling pos ition, the M708 is turned on to carr y out the s ec ond stap li ng. When the conti nuo us sta pli ng is s ele ct ed
at this time, the stapler remains at the second stapling position in front.
After completion of printing, the stapler returns to the home position.

STAPLER SECTION
4.2.2 Staple control
When in the stapl e mode, st apling is made by th e drivin g force of th e M708 (Sta pler m otor). Thr ough the
control of the PS712 (Stapler HP sensor), the M708 makes one rotation.
The maximum number of sheets of paper that can be stapled and the operation when the stapling is not
allowed can be set by using the 25 mode DIP SW.
A. No staple detection control
B. Operation after changing a staple cartridge
II UNIT EXPLANATION
When the PS713 (Stapl e detec tion sens or) det ects t he no st aple c onditi on, the m essage o f no stap le
is displayed on the LCD of the main body.
After changing a staple cartridge, the M708 is driven for blank stapling until the PS714 (Stapler ready)
detects staples, to set the staples at the stapling position.

5.2.3 Tray up/down control while in print operation
When the PS706 (Tray lower limit sensor) is off with the power on, the M706 (Tray up/down motor) rotates
backward to lift down the tray unit. The tray unit stops when the PS706 is turned on.
The number of option tray s i nst alle d (1 tray, 2 trays, or no optional tray ) is cou nted by the fol lo win g ope r ations.
When the PS716 (Tray count sensor) is off during the de tection of the tra y lower limit that is performed
when SW2 (Sub power sw itch) is turned ON, it is jud ged that th er e is no op tio nal tray p rovi ded . And when
the PS716 is on, it is judged that the optional tray 1 is installed. And then the M706 rotates forward to lift
the tray unit by one stage up and stops. At this time, when the PS716 is on, it is judged that the optional
tray 2 is installed.

How to use this catalog
This parts catalog includes illustrations and part numbers for all replacement parts and assemblies used in this model.
Model-specific parts are identified in the illustrations with reference
numbers. Use the reference number to locate the corresponding part
number on the facing page.
Common hardware items, such as screws, nuts, washers, and pins, are
identified in the illustrations with reference letters. Use the reference letter to locate the corresponding part number on the hardware listing in the
lower right hand corner of the facing page.
If you know a part number, but don’t know where the part is used, use
the numerical index to determine the page number and reference number for that part. Because some common parts are used in several
places, there may be more than one entry. Refer to the illustrations to see
where the part may be used.
If you know a part’s description, but don’t know where to look to find
the part number, use the alphabetical index to determine likely page and
reference numbers. Then look at the illustrations to determine that you
have identified the correct part. Locate the part number using the listing
on the opposite page.
Retail pricing that appears with the numerical index, while valid when
this catalog was printed, is subject to change without notice. The prices
are only suggested prices and are provided only for reference. Dealers
may determine their own selling prices. For up-to-date pricing, refer to
current Konica price lists or contact the Konica Parts Distribution Center.
How to order parts
Use standard Konica parts ordering procedures to obtain these parts.
For ordering options, contact Konica’s Parts Distribution Center.
When ordering parts, be sure to specify part numbers exactly as listed in
this catalog.
