Stapler Unit Movement B793 48 SM 2.8 STAPLER UNIT MOVEMENT The machine has only one stapler [A]. It does stapling for booklets and for corner stapling. The stapler unit motor [B] moves the stapler fr om side to side. The stapler unit HP sensor [C] detects when the stapler unit is at home position. In corner staple mode, at the start of the j ob, the stapler moves to the position where the stapler will be inserted. In booklet mode, at the start of a job, the stapler moves to a starting position that depends on the paper size, as follows: ƒ 8.5 x 14 inches or shorte r: Rear side staple position ƒ Longer than 8.5 x 14 inches: Center position. When the st apler is at the center position, bracket [E] rel eases ‘stopper L’, which ca tches the bottom edge of the paper for booklet stapling with longer paper sizes. This will be described in a later section. If the stapler safety sensor [D] detects the stapl er unit at its initialization, the stapler unit stops moving until the stack feed out belt pawl and stopper S are at home position. If the stapler unit does not stop, it could collide with the pawl and/or the stopper.
Stacking for Booklet Stapling SM 49 B793 B793 Booklet Finisher 2.9 STACKING FOR BOOKLET STAPLING 2.9.1 OVERVIEW There are two stoppers near the stapler unit. T hese stoppers hold the stack of paper in the correct position during stacking. The stoppers are called ‘stopper S’ and ‘stopper L’. Stopper S is used for legal size paper, or shorter than 8.5 x 14 inches. Stopper L is used for paper that is longer than 8.5 x 14 inches. ƒ In corner stapling mode, the pawl on t he stack feed-out belt holds the stack of paper. For booklet stapling, this pawl stay s at home position, which is on the rear side, so it does not inte rfere with booklet stapling. 2.9.2 8.5 X 14 (LEGAL) OR SHORTER At the start of the set, the upper retracti on motor [A] turns on, and stopper S [B] moves down into position to catch the paper . The upper retraction motor also moves the upper clamp roller [C] into contact with the stack .
Stacking for Booklet Stapling B793 50 SM When the stack is complete, stopper S moves away [D], and the machine feeds the stack to the correct position for stapling. To do this, the upper clamp roller motor [E] rotates the upper clamp roller. 2.9.3 LONGER THAN 8.5 X 14 INCHES At the start of the set, the stapler moves to the center position. At this position, a bracket [A] on the stapler unit pushes stopper L [B]. The pawl [C] on the stopper L assembly then moves into position to catch the paper. T he upper clamp roller holds the stack (see the
Stacking for Booklet Stapling SM 51 B793 B793 Booklet Finisher previous section). When the stack is complete, the stapler mo ves to the rear-side position, and stopper L moves away. The machine feeds the stack to the correct position for stapling.
Moving the Stack to the Folding Position B793 52 SM 2.10 MOVING THE STACK TO THE FOLDING POSITION First, the upper clamp roller feeds the sta ck down after the stack has been stapled. When the lower clamp roller [A] catches the stack, the upper clamp roller stops, and the lower clamp roller feeds the stack down. The lower clamp roller is released just befor e the leading edge of the stack reaches the bottom fence [B] (this fence cons ists of two pawls that catch the paper). The bottom fence moves the stack to the folding position The fold roller motor [C] tu rns the lower clamp roller. The lower retracting motor [D] moves the lo wer clamp roller against and away from the stack. The lower clamp roller HP sensor [E] det ects when the lower clamp roller is moved to the home position. The bottom fence lift motor [F] moves the bottom fence up and down. The bottom fence HP sensor [G] detects when the botto m fence is at home position.
Folder SM 53 B793 B793 Booklet Finisher 2.11 FOLDER 2.11.1 OVERVIEW The fold plate pushes the stack into the nip bet ween the fold rollers. The fold rollers feed out the stack, then reverse to feed it back in agai n. Then, the fold rollers feed the stack out of the folder, to the booklet tray. 2.11.2 FOLD PLATE [A]: Bottom Fence Stack Stoppers. Catches t he stack after it is released by the clamp rollers. [B]: Fold Plate Motor. Drives the timing belt and gears that move the fold plate. [C]: Fold Plate Cam. Controls the movement of t he fold plate to the left (into the nip of the fold rollers) and right (toward the fold plate home position). [D]: Fold Plate HP Sensor. Controls operation of the fold plate motor. [E]: Fold Plate. Moves left and pushes the st ack into the nip of the fold rollers and then moves right to retract.
Folder B793 54 SM 2.11.3 FOLD ROLLERS [F]: Fold Roller Motor. Drives forward to feed out the stack at the fold, and then drives forward again to feed out the folded stack. ƒ This cycle can be repeated by changing the setting of SP6136. [G]: Fold Rollers. Driven by the fold roller motor, this roller pair feeds out the stack at its fold, reverses to feed in the stack to, and then feeds forward again (assisted by the fold unit exit rollers – not shown) to feed out the stack to the lower tray.
Punch Unit SM 55 B793 B793 Booklet Finisher 2.12 PUNCH UNIT 2.12.1 OVERVIEW OF OPERATION Skew Correction Before Punching The finisher entrance roller corrects for paper skew and then the punch unit moves across to punch the holes at the correct position. Each sheet is punched one at a time. Paper feeds out of the copier. The finisher entrance sensor [A] detects the leading edge of the sheet. The finisher entrance roller [B] stops rotating br iefly while the copier exit rollers continue to rotate. This buckles the paper against the fi nisher entrance roller to correct skew. The finisher entrance roller starts to rotate again and feeds the sheet into the finisher. These SP codes adjust the ske w operation in the punch unit: ƒ SP6130. This SP corrects the punch hole ali gnment. To do this, it corrects the skew of each sheet by adjusting the amount of time the finisher entrance roller remains off while the exit roller of the machine rema ins on. For more, see Section 5. Service Tables. ƒ SP6131. This SP determines w hether the finisher entrance roller stops to correct skew when paper enters the finisher. You can use this SP to disable the skew correction. For more, see Section 5. Service Tables.
Punch Unit B793 56 SM Punch Unit Position Correction These operations (skew correction before pu nching, and punch unit position correction) increase the accuracy of the punch alignment. The trailing edge of the sheet passes the finisher entrance sensor [A]. The paper position slide unit moves the paper po sition sensor [B] forward to the edge of the paper. The paper position sensor detects the position of the paper edge and sends this information to the punch unit board. The machine uses the detected position of the paper edge to calculate the correct position for punching. The upper transport motor switches on and ro tates the feed rollers [C] the prescribed distance to put the paper under the punch unit [D]. Using the result of the posit ion calculation, the punch unit control board moves the punch unit [D] to the adjusted punch position. The paper position slide unit and its paper sens or, move back to the paper position slide home position sensor [E], and the punch unit fires the punches to make the holes. The feed rollers feed the punched paper out of the punch unit and into the paper path. The punch unit moves back to home position (det ected by the home position sensor [F].
