When an original is set on the DJF feed table, th e lea din g edge is stopp ed by
the stopper [A], and the feele r [B] activa te s the origin al set senso r. The Insert
Original indicator light goes out an d the DJF informs the copie r’s CPU that
the originals have been set.
When the Start key is pressed, the copier’s CPU sends the feed-in signal to
the DJF. On receipt of this signal, th e sto pp er sole no id [C] activa tes to raise
the stopper to allow the originals to be fed in, and to lower the press rollers

The feed-in clutch [A] activat es when the DJF receive the feed-in signal.
200ms after the feed-in clutch act ivate, the feed-in motor feeds all originals to
the feed roller [B].
When the originals reach the fee d rolle r, th e sto pp er sole no id [C]
de-activates to lower the original sto pper [D] and to lift up the origina l press
rollers [E].
When the originals pass through (be twe en the sepa rat ion belt [F] and feed
roller), only the lowest orig ina l is sep ara te d an d fe d on to the exposure glass.
Until then, the feed-in motor rotates slowly (372mm/sec) to ensure prop er
original feeding. When the lea ding edge of the original activates regist rat ion
sensor - 2 [G], the feed-in clutch [A] turns off to reduce the mechanical load
and prevent the next original fro m f eeding. Also, the feed motor rotat es more
quickly (1250mm/sec).

BASIC OPERATION 23 April 1993
[C][B]
When the leading edge of the original reaches the exposure glass, the
original is transported by the tra nsport belt [A] (belt drive motor turns on 200
ms after the start key is pressed).
When the trailing edge of the orig ina l passes through registration sen sor - 1
[B], the feed-in mot o r tu rns off. When the trailing edge of the original passes
through registratio n sen sor - 2 [C], the belt drive mot or gra du ally de crea ses

200ms after the belt drive motor turns off, the feed -in mot or tu rns on until the
next original activates reg istra tion sensor - 1 [B], the next original waits until
the first original copy jobs comple te . This op era tio n red uces the original feed
in time.
When the scanner reaches the return position, the copier’s CPU sends the
feed-out and feed-in signals to the DJF CPU in order to exchange the original
for the next original.
When the DJF receives the feed -out signal, the belt drive and fe ed -ou t
motors turn on.
When the scanner reaches the return position after scanning the last original,
the copier’s CPU sends only the fe ed-out signal to feed-out the last orig inal.
If the original is smaller than A4 sideways, the origina l just copied is
transported to the rig ht sid e of the expo sure glass then waits until the next
original copying is completed . The n the previous original is delivered . This
operation also reduces the original fe ed-in time .

Unlike one-sided original feed, the back side of the original must be copied
first to keep the originals and copies in the correct order.
During original feed-in, the sequence is the same as fo r one-side d feed ;
however, the belt drive motor con tin ue s rota ting until the original reaches the
inverter section. The DJF CPU also energize the feed-out motor and the
inverter solenoid [A] fo r a short time.
After the inverter mechanism inverts the original (10 pulses after the feed-out
sensor [B] activates), the belt drive mot or reve rses an d th e orig inal is fed
towards the original scale. It is stoppe d at the correct posit ion on the
exposure glass, and the DJF CPU sends th e cop y start signal.
When the scanner reaches the return position, the copier’s CPU sends the
invert original signal to the DJF CPU in order to ma ke a cop y of th e fro nt sid e.
The original is inverted in the same way as for back side copying.

second set of origina ls [D] ha s bee n set (st oppe d by the original stopper [E] )
and the first set of originals [A] are all fe d-in , th e orig ina l set sensor feeler [B]
is still actuated and only the original feed sensor is deactuated. There fo re,
the copier’s CPU recognizes tha t th e first jo b is comple ted.
If the second job is alrea dy pre set, the second set of originals is a ut oma tically

4.4 COMBINE 2 ORIGINALS MODE
4.4.1 Overview
[Fig.1]
2 originals are fed onto the exposure glass at once in the comb ine 2 origin als
mode as shown in figure 1. This allows copying 2 originals onto one sheet of
paper automatically either in the full size mod e or in the red uction mode. If it
is used together with the dup lex mod e, 4 originals can be copied on a single
sheet of paper automatically.
If odd numbered originals are place d on the origin al ta ble, the first original is
placed on the exposure glass as sho wn in fig ure 2.
Only 1-sided originals can be used, and Auto Pa per Select (APS) and Auto

The DF operation in the combine 2 original mode is as follows:
[Figure 1]
The first original is fed in the same manner a s the one -side d orig ina l
mode. When registration sensor-2 det ect s the trailin g edge of the first
original, the feed-in and the belt drive motors sto p once and the feed -in
clutch turns on again to pre pa re for the second original fee d.
[Figure 2]
As soon as the feed-in and the belt drive motor turn off, the belt drive
motor starts rotatin g in reve rse to align the first original against the
original scale. Then the belt drive mo tor t urn s off .
[Figure 3]
50ms after the feed-in motor turns off, the feed -in mot or tu rns on again at
a lower speed (372mm/sec) to feed the secon d orig ina l.
A few pulses (0 ~ 14 pulses: depends on the SP mode adjust men t) after
the registration senso r-2 is a ctiva ted by the leading edge of th e seco nd
original, the feed-in motor and the feed-in clutch turn off.

[Figure 4]
Soon after the feed-in motor turns off, both the feed-in and the belt drive
motors turn on again at the lower speed (372mm/sec).
After registration sen sor-2 detects the trailing edge of the seco nd origin al,
the feed-in and the belt drive motors turn off and gradually th e belt drive
speed reduces to sto p the original at the pro pe r p lace on th e exposure
glass.
[Figure 5]
After the copying of th ese origin als is f inish ed , the belt drive motor and
the feed-out moto r t urn on to fee d ou t th e originals. 50mm before the
trailing edge of the first original de-activates th e feed-ou t sen sor, both the
belt drive and the feed-out motor rotate at the lower speed to improve
original stacking.
48 pulses after, the belt drive motor turns off and 60 pulses after the
feed-out sensor d et ect the trailing edge of the second original, the
feed-out motor turns off.

The drive from the feed-in motor [A] is transmitt ed to the pick-u p rollers [ B]
and the feed roller [C] through the feed-in clutch [D] as shown. The feed roller
and the friction belts [E] are used to feed -in and sep ara te the origin als [F] .
Only the bottom original is fed because the friction belt prevents any other
original from feeding.
Original feed starts when the feed roller starts turning and advances the
bottom original of the stack. The feed roller moves the original past the
separation belt because the driving force of the feed roller is greater than the
resistance of the friction belt . The friction belt prevents multiple fee ds
because the resistance of the frict ion belt is great er th an the frictio n be twe en
original sheets.

Normally the separation belt is not driven . Whe n the cop y jo b is comple te d,
the separation solenoid [A] activates for 100ms. to transmit the drive from the
feed-in motor [B] to th e sep aration belts [C] as shown.
By this operation, the part of th e frict ion belt that contacts the feed roller [D]
or the original changes to prevent multiple feeding .
When the pasted original mode is selected, the separa tio n solenoid turns on
to drive the separation belt in the same dire ction as the feed rollers.
This disables the separa tion function to reduce the frictio n be tween the
original surface and the separation belt.

THIN / THICK ORIGINAL MODES 23 April 1993
7. THIN / THICK ORIGINAL MODES
This document feed er ha s two dif ferent ways of stopping orig ina ls a t th e
correct position on the exposu re gla ss. They are called the thin original mode
and the thick original mode. The mode used is dete rmined by using the
copier’s User Tool No.12.
1. Thin Original Mode
The original is stopped at the corre ct po sitio n on the expo sure glass
based on encoder pulse count. The belt drive motor stops shortly after
the original trailing edge passes registration sensor - 2. (Exact timing
depends on registration adju stme nt .)
In the pasted original mode, the DJF automatica lly se lect s this mod e.
2. Thick Original Mode
When thick original mode is selecte d, the belt drive mot or rema ins
energized to carry the original approximately 10 mm pass the left scale.
Then, the belt drive motor pauses and reverses to feed th e orig inal back
against the original scale. This forces th e orig ina l aga inst the left scale
and thus aligns the trailing edge of the original with the scale.
Thick original mode is selected at the factory.

23 April 1993 ORIGINAL SIZE DETECTION
8. ORIGINAL SIZE DETECTION
[F]
The DJF detects original widt h through the on/off combination of the three
original width sensors -1 [A], -2 [B] , -3 [C] , it also detects the original length
through the use of the registration sensors -1 [D], -2 [E] and the pulse count
sensor [F].
[D]
[C]
[G]
[A]
[B]
The DJF CPU counts the pulses between regist rat ion sensor - 2 [E] on timing
and registration senso r - 1 [D] off timing.
Based on this pulse count, the CPU dete rmine the origin al len gt h.
The reason for using two registration sensors are:
1) Registration sensor -2 [E] is used to sto p the pre -fed original to wait until
the previous original is fed out. For p recise cont rol, the origin al sto p
position must be after the pull out rollers [G ]. Therefore, registration
sensor -2 is placed after the pull-out roller.
2) Registration sensor -1[D] checks the trailin g edge of the origina l. This
check is used to place the orig inal on the exposure glass.
Enough distance is required bet ween the sensor and the orig ina l scale.
Therefore, registration sensor -1 is placed 34.9 mm before sensor -2.
The original size is determine d by the combination of the det ect ed origin al
width and the length.

When the DJF is opened, the lift springs [A ] pro vide enough force to ensure
that the DJF does not fall onto the expo sure glass. When the DJF is closed,
points "➀", "➁", and "➂" are aligned and no upward force is provided to the
DJF.
The lift switch [B] is actuated when the DJF is closed . The copie r t hen shif ts
to the document feeder mo de. The lift switch also serves as the reset switch
for DJF misfeeds.
When a book or thick (maximum thickness 60 mm) original is copied, the DJF
acts as a cover for the original as sh own in the figu re [C] . The lift switch is
turned off during th is co ndition, so the DJF does not function. The tension of
spring [D] returns the DJF to the norma l condition after copying a thick
original.
