Page 275 Outline of Mechanism 1 July 1994 1.5.2 Paper transport process Simplex copy mode In the simplex copy mode, copies are stacked on the copy tray with the image side down as shown. In the finishing modes, copies are inverted and stacked on the shift tray in page order as shown by the dotted line.
Page 276 1 July 1994 Outline of Mechanism 1.5.3 Original transport process SADF mode In the SADF mode, the original is set with the image side down and transported from right to left. ADF and RDH modes There are two copy modes: sort and stack. In the stack mode copies of the same page are grouped together.
Page 277 Outline of Mechanism 1 July 1994 Duplex original to duplex copy or simplex copy mode In these modes, the original is set with the image side down on the original table and is transported as shown. The original is stopped on the exposure glass and the front side of the original is exposed first.
Page 278 1 July 1994 Outline of Mechanism Simplex originals to duplex copy mode Copy paper motion for odd originals The original motion in the RDH is just like the simplex original to simplex copy mode. In case of the other RDH and finisher systems, usually two cycles of the simplex original feeding makes one set of duplex copies.
Page 279 Outline of Mechanism 1 July 1994 This is because the originals copied on the front and reverse side are alternately copied due to the alternate paper feeding system. As the margin can be adjusted by changing the original flash (exposure) timing, the original stop on the exposure glass must correspond to the adjusted flash timing.
Page 280 1 July 1994 Outline of Mechanism Duplex original to simplex copies mode One cycle of original feeding makes one set of copies. For each original feeding, the front side image is copied and the copy is stacked in the duplex tray. Then the original is inverted in the RDH and the reverse side image is copied onto the copy from the duplex tray.
Page 281 Outline of Mechanism 1 July 1994 1.5.4 Alternate paper feeding timing chart *1 to *8 on the charts show the key points for understanding the alternate paper feeding. Refer to the explanation below for each key point. The timing charts are based in the following copy mode conditions: Left One: Two sets of copies are made from 10 originals in the simplex original to duplex copy mode.
Page 282 1 July 1994 Outline of Mechanism "Paper Feed Timing" shows the timing when each paper is fed from the LCT. The numbers correspond to the number of the original which will be copied on the front side of the paper. The chart shows only odd number because the even numbered originals are copied on the reverse side of the paper.
Page 283 Outline of Mechanism 1 July 1994 1.5.5 Cover sheet and chaptering modes Even in the duplex copy mode, the copy for the original which is designated as the cover and slip sheets does not enter the duplex tray. This is to enable the use of copy paper up to 163 g/m of paper weight.
Page 284: Total
1 July 1994 Outline of Mechanism How the designated original is copied in the duplex original to duplex copy mode In the duplex original to duplex copy mode, although the original designated with the cover or chaptering mode is always copied on the front side of the cover or slip sheet, it is copied during the second original feeding cycle, not during the first one.
Page 285 Outline of Mechanism 1 July 1994 During the Last Original Feeding Cycle Normal original motion After completing the copy run, one more original feeding is done. This is to return the designated original, which had been made side down during the first original feeding cycle, into the original setting.

Page 405 1 July 1994 Duplex and Paper Exit 4 As the air knife solenoid is operated according to the number of sheets stacked when duplex stacking is completed, the number of sheets fed are counted by the duplex paper feed sensor. 5 The OFF timing of the vacuum solenoid is deter- mined 0.1 second after determining that all the paper on tray has been fed.
Page 406 Duplex and Paper Exit 1 July 1994 7 During duplex paper feeding, transfer time from the 2nd duplex paper feed sensor turns ON to when the reg- istration sensor turns ON is measured as for like the 1st to 3rd tray paper feed. The feed motor ON timing for the 2nd time is changed.

Page 446: Basic Operation
Finisher 1 July 1994 2.17.2 Basic operation Inverter When the finisher is used in the single side copy mode, copies are always guided to the inverter tray as shown by the dotted line in the above illustration. The copies are inverted then delivered to the shift tray [F] with the image side down.
Page 447 1 July 1994 Finisher 2.17.3 Inverter junction gate operation In the single side copy mode, if one of the finishing modes is selected, the inverter junction gate solenoid [A] is energized when the copier exit sensor (the eject junction sensor) detects the first copy. The junction gate pawls [B] are switched so that copy paper is directed into the inverter tray (downward).
Page 448 Finisher 1 July 1994 2.17.5 Paper delivery switching Depending on the selected finishing mode, the copies are directed up or down by the junction gate [A]. A two-way solenoid is used to control the junction gate. When the exit sensor of the copier is activated while in staple mode, the solenoid [B] pulls the plunger in the arrow [C] direction.
Page 449: Jogger Movement
1 July 1994 Finisher 2.17.7 Shift tray side to side shift mechanism In the sort/stack mode, the shift tray [A] moves side to side to stagger and separate sets of copies. The horizontal position of the shift tray is controlled by the shift motor (dc motor) [B] and the shift cam (helical cam) [C].
Page 450 Finisher 1 July 1994 2.17.10 Stapler The staple hammer [A] is driven by the staple motor [B] via gears [C], two eccentric cams [D], and two links [E]. After all copies are stacked in the jogger tray, the stack is held by the jogger fences. Soon after this, the staple motor starts rotating to staple the copy stack.
Page 451 1 July 1994 Finisher 2.17.12 Feed-out to shift tray After being stapled, the stack feed out motor [A] starts rotating. The pawl [B] on the lift belt [C] transports the set of stapled copies up, and feeds it to the shift tray. Approximately 0.6 second after the stack feed out motor starts, the motor stops for 400ms.
