4.1 NORMAL (PROOF MODE) AND SORT/STACK MODE

[C]

[B]

[A]

Options

A664D500.wmf

Copies exiting the copier pass through the entrance guide plates to the turn gate section. The turn gate [A] will send copies either to the proof tray or to the bins, depending on the mode.

– Normal (proof) mode (from the turn gate section to the proof tray) –

The turn gate solenoid energizes to turn the turn gate clockwise when the

key is pressed. The turn gate directs copies through the proof transport section to the proof tray. The main motor turns counterclockwise to rotate the vertical transport rollers [B] and proof exit roller [C].

A664D501.wmf

In this mode, the turn gate solenoid stays off to keep the turn gate [A] at the upper position. The main motor turns clockwise to rotate the sorter transport rollers [B] and the exit motor rotates the exit rollers [C].

The turn gate directs copies to the sorter bins through the sorter transport section, then the first copy is delivered between the top bin [D] and the upper guide plate [E]. The jogger plate [F] then jogs to square the copies each time.

Before the next copy reaches the sorter exit roller, the bin drive motor [G] rotates and advances the bin one step (the helical wheels [H] rotate once). When the cut out in the actuator reaches below the wheel sensor [I], the bin drive motor turns off.

Bins advance each time copies are delivered.

As with sort mode, the turn gate solenoid stays off and the turn gate [A] stays up when the

key is pressed. The main motor turns clockwise to rotate

the sorter transport rollers [B] and the exit motor rotates the exit rollers [C]. The turn gate directs copies to the sorter bins through the sorter transport

section, then the copies are delivered between the top bin [D] and the upper guide plate [E]. The jogger plate [F] then jogs to square the copies each time.

All copies of the copy run are then fed to the first bin. When the final copy is delivered, the wheel drive motor [G] turns and advances the bin one step (the helical wheels [H] rotate once). When the cut out in the actuator reaches below the wheel sensor [I], the bin drive motor turns off.

A664D504.img

When the final set of copies is jogged [Fig. 1], the stapler unit staples the stacked copies as follows:

The grip arms move inside the front side plate and catch the paper. The bin rear plate is turned so as to be flat with the sorter bin. The grip assembly brings the copies down underneath the stapler [Fig. 2]. The staple unit changes position (the position varies depending on the copy

size and staple mode) and the stapler staples the copies [Fig. 3].

[Fig. 5]

A664D506.img

The grip assembly brings the stapled copies back to the bin and the bin rear plate returns to the original position.

The grip assembly releases the copies and returns to outside the front side plate so as not to disturb the bin movement [Fig. 4].

The bin advances one step [Fig. 5]. When the final set of copies is stapled, the stapler unit is returned to the

home position. There are two staple modes.

1) Automatic stapling:

In ADF mode, when staple mode is selected before pressing the

key,

copies will be delivered to each bin and stapled automatically.

2) Manual stapling:

In sort mode, after copies are sorted in the bins, the copies will be stapled when the manual staple key is pressed and the staple position is selected. In stack mode, manual stapling is impossible.

The turn gate [A] sends copies to the proof tray or the sorter bins depending on the mode. In the proof mode, the turn gate solenoid [B] turns on and the main motor [C] turns clockwise when the

key is pressed. The turn gate [A], directs copies upward through the proof transport section to the proof tray. In this mode, main motor drive is transmitted by both the proof drive belt [D] and sorter drive belt [E]. However, the one-way clutch in each sorter transport roller drive gear [F] does not transmit the drive to the sorter transport rollers.

In the sort, stack, and staple modes, the turn gate solenoid stays off to direct copies downward to the sorter transport section. When the

key is pressed, the main motor [C] turns counterclockwise. In this mode, main motor drive is not transmitted to the proof drive belt [D] because of the one-way clutch in the pulley [G]. The entrance [H] and the proof exit [I] sensors check for paper jams.

The bin drive mechanism moves the bins up and down to receive copies. The main components in this mechanism are the bin drive motor [A], the two helical wheels [B], the wheel sensor [C], and the bins themselves [D]. There are four pins on each bin. Two of them fit in the slots in the helical wheels. Another pin fits into the slot [E] in the front side frame, and the last pin fits in the guide rail [F]. The pins slide up and down in these slots.

Two timing belts transmit drive from the bin drive motor to the helical wheels. When the motor rotates clockwise, the bins lift (black arrow) and when it rotates counterclockwise, the bins lower (white arrow). The wheel sensor actuator on the front helical wheel has a slot which detects when the helical wheel has rotated 360 degrees.

When the bins are advanced, the helical wheels rotate once (360 degrees) for each step.

As the pitch of the spiral on the helical wheel is greater when bins are at the staple and paper exit area than when bins are elsewhere, the amount of bin shift is greater when bins are at the staple and paper exit area. This leaves enough space to staple [G] and stack paper [H] and reduces the total machine height.

The bin home position sensor [A] and the wheel sensor [B] ensure that the sorter exit roller is between the upper guide plate [C] and the 1st bin [D] when all the bins are at the home position.

When the main switch is turned on, the bin lift motor [E] lowers the bins (turns counterclockwise) until the bottom bin actuates the bin home position sensor. Then, the bin lift motor raises the bins (turns clockwise) until the wheel sensor activates. At this point, the bins are in the home position.

•

NOTE:

The bin jam detector contains two LED/phototransistor pairs.

•

To detect jams, light from an LED above the bins passes through the slots in the bins to a phototransistor below the bins. If the light path is blocked at the wrong time, a jam is detected.

•

To detect paper in the bins, light from another LED above the bins passes through the circular holes in the bins to another phototransistor below the bins. If the light path is blocked, the machine determines that there is paper in the bins.

When the

key is pressed in the sort, staple, and stack modes, the copier sends the paper size information to the sorter stapler. In accordance with this data, the jogger motor [A] drives the jogger plate [B] from the jogger home position to a point 10 mm wider than the selected paper.

Options

300 ms after the trailing edge of the copy passes underneath the bin jam sensor (jam detection part), the jogger motor rotates forward and in reverse. This makes the jogger plate push all the copies against the front side plate to square the sheets. When the jogger plate pushes the paper, the plate shifts to a position 5 mm wider than the paper size when the bins lift, and it shifts to a position 1 mm narrower than the paper size when the bins lower.

The jogger plate then returns to 10 mm away from the selected paper size for the next copy.

When the bin jam sensor (paper detector part) detects that all copies have been removed from the bins after jogging is finished, the jogger plate returns to its home position.
