There are three ejection paths to tray 1 and 2 depending on the ejection processing.
There is only one paper ejection path to the escape tray. When the equipment is set to non-sort, all copies are ejected through the following path. Stack ejection roller. This is the copy ejection path when the equipment is set to sort for paper size other than A4, B5, or LTR or when set to staple sort. Copies are delivered to the processing tray for aligning and stapling. Then they are ejected using the rear end assist. Feed two sheets of paper to buffer two or three sheets if 2-point stapling.
Then they are aligned and stapled in the processing tray and ejected. Even while stapling or offset is being performed, simultaneous stack ejection, which simultaneously ejects copies delivered to the buffer and post processed stack in the processing tray, is performed because copies are received continuously from the host machine. The stack delivered from the buffer is ejected to the processing tray and the stack processed in the processing tray is ejected to the tray.
Simultaneous stack ejection operation is described below for two A4 copies between stacks when the equipment is set to sort. At the same time, the stack in the processing tray is delivered toward the delivery tray by the return roller and rear end assist guide. Return roller. When the escape tray is specified as the destination of paper ejection in the non-sort mode, the paper delivered from the host machine to the finisher is rerouted to the path shown below by the escape inlet flapper and ejected to the escape tray.
Escape delivery roller. The paper output mechanism serves to keep a stack of sheets coming from the finisher in place for the next steps stapling, folding.
The paper inlet is equipped with the No. The paper positioning plate is kept in wait at a predetermined location to suit the size of paper. The paper positioning plate is driven by the paper positioning plate motor M4 , and the position of the plate is identified in reference to the number of motor pulses coming from the paper positioning plate home position sensor PI7.
A sheet moved by the inlet roller is handled by the feed rollers and the crescent roller and held in a predetermined position. The feed plate serve to move sheets by coming into contact with or moving away from sheets as needed. The alignment plates put the stack into order each time a sheet is output. The alignment plates are driven by the alignment motor M5 , whose position is identified in reference to the number of motor pulses coming from the alignment plate home position sensor PI5.
To prevent interference between paper and the paper folding rollers when the paper is being output, the folding rollers are designed to be covered by a guide plate. The guide plate moves down before paper is folded so as to expose the paper folding rollers.
The inlet is equipped with the No. Inlet motor. Saddle inlet. Guide motor drive signal. Alignment motor drive signal.

A copy arriving in the finisher from the host machine is routed to the saddle stitcher by the saddle inlet flapper. The saddle stitcher executes stitching and saddling operations on the copy and then delivers it to the saddle stitcher tray. The stitcher unit receives sheets from the finisher unit and outputs them inside the vertical path in vertical orientation. The vertical path, while sheets are being output, is configured by two paper deflecting plates.
Sheets coming later are output closer to the delivery slot, and the volume of paper that may be output is as follows:. The alignment plates operate to put the sheets in order each time a sheet of paper is output to the vertical path assembly.
The alignment plates are mounted at the edge of the vertical path assembly. The alignment plates also operate after stapling to prepare the stack for delivery. When all sheets have been output, the two stitchers stitch the stack. The stitchers are positioned so that they face the center of a stack. The two stitchers are not operated simultaneously so as to prevent the paper from wrinkling between two staples and to limit the load on the power supply.
The operation will be suspended if paper has already been picked up and delivered; the display of the host machine will indicate a message prompting the removal of the paper. Driving the Stack Delivery Belt 1. Outline of Operations The stack delivery belts are driven by the stack handling motor M2 , and the two are moved in parallel at the same time.
At the beginning of operation, the stack handling motor M2 is driven to set the stack delivery lever to home position. Outline of Operations The stack delivery belt operates as follows: 1 A sheet is delivered and deposited in the intermediate handling tray.
As may sheets as are specified are deposited in the intermediate handling tray. Thereafter, the stack delivery belt is stopped once in front of its home position. The front aligning plate is driven by the front alignment motor M3 , while the rear aligning plate is driven by the rear alignment motor M4. The front aligning plate home position sensor S6 and the rear aligning plate home position sensor S7 are used to detect the home position of the respective aligning plate.
The following shows the position of alignment and the sizes for alignment: Type of sort Non-sort Staple sort Sort Position of alignment Alignment front Front alignment Offset alignment T Reference: The machine initializes itself at the start of operation. Controlling the Alignment Motor F is a block diagram of the drive circuit used for the front alignment motor M3 and the rear alignment motor M4.
Both motors are 4-phase stepping motors. Front Alignment staple sort The machines stapler is used in place at the front and, therefore, sheets are stapled at the front. A sheet is delivered by the host machine, and is deposited to the intermediate handling tray. When the sheet reaches the intermediate handling tray, the return roller butts it against the stopper plate to align it in feed direction, moving the sheet to stapling position. Thereafter, the rear aligning plate is driven and the sheet is aligned to the front.
Offset Alignment non-stapling a. Sort In sort mode, each stack of sheets is displaced for alignment, referred to as offset alignment. A stack of sheets is displaced by 20 mm. The first stack is displaced to the front i. Fa The stack is then aligned by either the front or rear aligning plate. To align to the front, the rear aligning plate is used; to align to the rear, on the other hand, the front aligning plate is used moving the plate to the edge of the stack. If the sheets are A4 or A3, the home position of the front aligning plate will be used as the reference when the alignment is to the front; the home position of the rear aligning plate will be used as the reference when the alignment is to the rear.
The aligning plate the rear aligning plate if aligning is to the front, or the front aligning plate if the alignment is to the rear is held in wait in home position. When alignment takes place, the aligning plate is driven as far as the edge of the stack to be offset from the home position. Fb If the number of sheets specified or of originals is in excess of the limit imposed on the intermediate handling tray, as many sheets as can be accommodated limit are delivered; thereafter, the subsequent sheets are aligned in the same direction.
Non-Sort In non-sort mode, the sheets are aligned where it would be offset to the front in sort mode. Outline of Operation a. Staple Sort The machine operates as follows in staple sort mode: 1 The host machine communicates the selection of stapling and paper size. Reference: If the number of originals exceeds the limit imposed on the intermediate handing tray, the stack in the intermediate handling tray will not be stapled but will be delivered to the delivery tray.
The subsequent sheets will not be stapled either. Offset Alignment The machine executes offset alignment as follows: 1 The host machine communicates the selection of sort and paper size. Stack handling motor: CW to deliver the stack. Stapling 1. Outline The machines stapler is fixed in position at the front, and is not designed to shift or swing. Stapling takes place at the same position, and a staple is driven from under the sheets. Reference: If the number of sheets specified or the number of originals exceeds the limit imposed on stapling, the machine will not staple the stack and instead delivers it to the stack tray.
Used to make sure that the sheets are where stapling takes place; otherwise, idle stapling is executed to enable stapling. Detects the home position for stapling. Used to make sure that a cartridge is inside the stapler unit. Remarks Inside the stapler unit Inside the stapler unit. Controlling the Stapler Motor F is a block diagram of the drive circuit for the stapler motor M6. Operation of the Delivery Tray 1. Outline The machine is equipped with a single delivery tray to which stacks of sheets are deposited after they have been aligned, offset, and stapled in the intermediate handling tray.
When the first stack of sheets has been deposited in the delivery tray, the delivery tray paper sensor S11 goes ON. The position of the delivery tray is monitored in reference to the number of clocks generated since it has left the delivery tray paper height sensor S The upper limit of the delivery tray is detected by the delivery tray upper limit sensor S13 , while its lower limit is detected by the lower limit sensor S The limit imposed on the delivery tray in terms of the number of sheets is recognized for the following: Reference of detection Paper height and the state of the delivery tray lower limit sensor Paper height or the count of the number of sheets.
Thereafter, it moves up to a point about 5 mm above the point at which the paper height sensor S10 detects the top surface of the paper in the delivery tray.
Delivery tray DOWN. Detecting the Height of the Stack in the Delivery Tray In all modes, the stack in the delivery tray is detected in reference to its height by the delivery tray paper height sensor S The delivery tray moves down until the delivery tray paper height sensor S10 goes off after the delivery of a stack.
Thereafter, it moves up to a point about 5 mm from the point at which the paper height sensor S10 detects the top surface of the paper in the delivery tray. If the delivery tray lower limit sensor detects the delivery tray while the delivery tray paper height sensor remains ON, the finisher controller PCB communicates the overstacking condition to the host machine; when the stack is removed, the delivery tray moves to home position, ready to receive the next delivery.
Delivery tray paper height sensor flag. Stacks in the Stack Tray T shows the maximum numbers of stacks that may be deposited in the stack tray. When stapling is selected, the limit imposed on stacking is considered in reference to the number of stacks in the stack tray, in addition to the height of paper. A stack of sheets increases the count by 1; a total of 30 counts causes an overstacking condition, and the fact will be communicated to the host machine, which in response indicates a message prompting the removal of the stacks.
Stacking 30 stacks of 30 stacks of 30 stacks of limit 30 sheets 20 sheets 15 sheets. Holding Paper in Place in the Delivery Tray The paper retaining lever serves to prevent the wrong detection of paper height otherwise caused by curling of the stack. The paper retaining lever is driven when the stack handling motor M2 rotates in reverse, operating as follows: When sheets are delivered to the delivery tray in the form of a stack, it is deposited on the paper retaining lever, which makes a single turn to hold down the paper.
Then, the delivery tray continues to move down until the delivery tray paper height sensor S10 goes OFF. The delivery tray then moves up to a point about 5 mm above the position at which the stack tray paper height sensor S10 detects the top surface of the paper. The foregoing operations are repeated to hold down the stack. When the delivery tray reaches the delivery tray upper limit sensor S13 and, as a result, the sensor sends a signal S13D to Q5, STCTCW2 will be cut off, causing the motor to stop rotating clockwise.
Likewise, when the delivery tray reaches the delivery tray lower sensor S12 and, as a result, the sensor sends a signal S12D to Q5, STCTCCW2 will be cut of, causing the motor to stop rotating counterclockwise. Outline 1. The inlet sensor S2 remains ON after all the following: the inlet sensor detects paper; the machine moves the paper as far as its trailing edge leaves the delivery roller; and the machine moves the paper another 21 mm.
