4.1 ONE-SIDED ORIGINAL FEED
[A] [B]
[C]
[A]
[D] When an original is set on the DJF feed table, the leading edge is stopped by the stopper [A], and the feeler [B] activates the original set sensor. The Insert Original indicator light goes out and the DJF informs the copier'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, the stopper solenoid [C] activates to raise the stopper to allow the originals to be fed in, and to lower the press rollers [D] to press the originals against the pick-up rollers as shown.

[E] [G] [B] The feed-in clutch [A] activates when the DJF receive the feed-in signal. 200ms after the feed-in clutch activate, the feed-in motor feeds all originals to the feed roller [B]. When the originals reach the feed roller, the stopper solenoid [C] de-activates to lower the original stopper [D] and to lift up the original press rollers [E]. When the originals pass through (between the separation belt [F] and feed roller), only the lowest original is separated and fed onto the exposure glass. Until then, the feed-in motor rotates slowly (372mm/sec) to ensure proper original feeding. When the leading edge of the original activates registration sensor - 2 [G], the feed-in clutch [A] turns off to reduce the mechanical load and prevent the next original from feeding. Also, the feed motor rotates more quickly (1250mm/sec).

BASIC OPERATION

[B]
[C]
[A]
When the leading edge of the original reaches the exposure glass, the original is transported by the transport belt [A] (belt drive motor turns on 200 ms after the start key is pressed). When the trailing edge of the original passes through registration sensor - 1 [B], the feed-in motor turns off. When the trailing edge of the original passes through registration sensor - 2 [C], the belt drive motor gradually decreases its speed to stop the original at the proper place on the exposure glass. 200ms after the belt drive motor turns off, the feed-in motor turns on until the next original activates registration sensor - 1 [B], the next original waits until the first original copy jobs complete. This operation reduces 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 feed-out motors turn on. When the scanner reaches the return position after scanning the last original, the copier's CPU sends only the feed-out signal to feed-out the last original. If the original is smaller than A4 sideways, the original just copied is transported to the right side of the exposure glass then waits until the next original copying is completed. Then the previous original is delivered. This operation also reduces the original feed-in time.

BASIC OPERATION
4.2 TWO-SIDED ORIGINAL FEED
[A]
[B]
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 for one-sided feed; however, the belt drive motor continues rotating until the original reaches the inverter section. The DJF CPU also energize the feed-out motor and the inverter solenoid [A] for a short time. After the inverter mechanism inverts the original (10 pulses after the feed-out sensor [B] activates), the belt drive motor reverses and the original is fed towards the original scale. It is stopped at the correct position on the exposure glass, and the DJF CPU sends the copy 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 make a copy of the front side. The original is inverted in the same way as for back side copying.

4.3 PRESET MODE
[E] [C] [B] [D]
[F]
[A]
Two sets of originals for independent copy jobs can be set on the original tray at the same time. While the first set of originals [A] remains on the original tray, both the original set sensor feeler [B] and original feed sensor feeler [C] are actuated. If the second set of originals [D] has been set (stopped by the original stopper [E]) and the first set of originals [A] are all fed-in, the original set sensor feeler [B] is still actuated and only the original feed sensor is deactuated. Therefore, the copier's CPU recognizes that the first job is completed. If the second job is already preset, the second set of originals is automatically fed to the feed roller [F] in the same manner as the first set of originals was.

4.4 COMBINE 2 ORIGINALS MODE
4.4.1 Overview
[Fig.1]
[Fig.2]
2 originals are fed onto the exposure glass at once in the combine 2 originals mode as shown in figure 1. This allows copying 2 originals onto one sheet of paper automatically either in the full size mode or in the reduction mode. If it is used together with the duplex mode, 4 originals can be copied on a single sheet of paper automatically. If odd numbered originals are placed on the original table, the first original is placed on the exposure glass as shown in figure 2. Only 1-sided originals can be used, and Auto Paper Select (APS) and Auto Reduce/Enlarge modes cannot be used with this mode.

4.4.2 Operation
Figure 1
Figure 2
Figure 3 The DF operation in the combine 2 original mode is as follows: [Figure 1] The first original is fed in the same manner as the one-sided original mode. When registration sensor-2 detects the trailing edge of the first original, the feed-in and the belt drive motors stop once and the feed-in clutch turns on again to prepare for the second original feed. [Figure 2] As soon as the feed-in and the belt drive motor turn off, the belt drive motor starts rotating in reverse to align the first original against the original scale. Then the belt drive motor turns off. [Figure 3] 50ms after the feed-in motor turns off, the feed-in motor turns on again at a lower speed (372mm/sec) to feed the second original. A few pulses (0 ~ 14 pulses: depends on the SP mode adjustment) after the registration sensor-2 is activated by the leading edge of the second original, the feed-in motor and the feed-in clutch turn off.

BASIC OPERATION
Figure 4
Figure 5 [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 sensor-2 detects the trailing edge of the second original, the feed-in and the belt drive motors turn off and gradually the belt drive speed reduces to stop the original at the proper place on the exposure glass. [Figure 5] After the copying of these originals is finished, the belt drive motor and the feed-out motor turn on to feed out the originals. 50mm before the trailing edge of the first original de-activates the feed-out sensor, 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 detect the trailing edge of the second original, the feed-out motor turns off.

ORIGINAL SEPARATION

5. ORIGINAL SEPARATION
[F]
[E]
[B] [C] [A] [B] [D]
[E] [C]
The drive from the feed-in motor [A] is transmitted to the pick-up 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 separate the originals [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 feeds because the resistance of the friction belt is greater than the friction between original sheets.

SEPARATION BELT DRIVE MECHANISM
6. SEPARATION BELT DRIVE MECHANISM
[B]
[D]
[A]
[C] Normally the separation belt is not driven. When the copy job is completed, the separation solenoid [A] activates for 100ms. to transmit the drive from the feed-in motor [B] to the separation belts [C] as shown. By this operation, the part of the friction belt that contacts the feed roller [D] or the original changes to prevent multiple feeding. When the pasted original mode is selected, the separation solenoid turns on to drive the separation belt in the same direction as the feed rollers. This disables the separation function to reduce the friction between the original surface and the separation belt.

THIN / THICK ORIGINAL MODES
23 April 1993
7. THIN / THICK ORIGINAL MODES
This document feeder has two different ways of stopping originals at the correct position on the exposure glass. They are called the thin original mode and the thick original mode. The mode used is determined by using the copier's User Tool No.12.
1. Thin Original Mode The original is stopped at the correct position on the exposure 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 adjustment.) In the pasted original mode, the DJF automatically selects this mode.
2. Thick Original Mode When thick original mode is selected, the belt drive motor remains energized to carry the original approximately 10 mm pass the left scale. Then, the belt drive motor pauses and reverses to feed the original back against the original scale. This forces the original against the left scale and thus aligns the trailing edge of the original with the scale. Thick original mode is selected at the factory.

ORIGINAL SIZE DETECTION
8. ORIGINAL SIZE DETECTION
[D] [E]
[C]
[F] [G] [A] [B] The DJF detects original width 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]. The DJF CPU counts the pulses between registration sensor - 2 [E] on timing and registration sensor - 1 [D] off timing. Based on this pulse count, the CPU determine the original length. The reason for using two registration sensors are: 1) Registration sensor -2 [E] is used to stop the pre-fed original to wait until the previous original is fed out. For precise control, the original stop position must be after the pull out rollers [G]. Therefore, registration sensor -2 is placed after the pull-out roller.
Dual Job Feeder
2) Registration sensor -1[D] checks the trailing edge of the original. This check is used to place the original on the exposure glass. Enough distance is required between the sensor and the original scale. Therefore, registration sensor -1 is placed 34.9 mm before sensor -2. The original size is determined by the combination of the detected original width and the length.
17
LIFT MECHANISM
23 April 1993
9. LIFT MECHANISM
[A] [D]
[C] [B] When the DJF is opened, the lift springs [A] provide enough force to ensure that the DJF does not fall onto the exposure glass. When the DJF is closed, points "", "", and "" are aligned and no upward force is provided to the DJF. The lift switch [B] is actuated when the DJF is closed. The copier then shifts to the document feeder mode. 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 shown in the figure [C]. The lift switch is turned off during this condition, so the DJF does not function. The tension of spring [D] returns the DJF to the normal condition after copying a thick original.
