Component Layout SM 37 B793 B793 Booklet Finisher Item No. Purpose Clamp Roller Motor Stapler Unit Motor 36 Moves the stapler from side to side. Lower Retraction Motor 40 Drives a large cam that alternately clamps and unclamps the lower clamp roller, which is the idle roller of the clamp roller pair. When these rollers are clamped, they are part of the paper feed path and feed the stack toward the bottom fence of the fold unit. When the idle roller is retracted, the stacks falls a very short distance (3 mm) onto the fold unit bottom fence below. These rollers remain unclamped while the bottom fence pos itions the stack for folding and while the stack is folded by the fold rollers. Fold Roller Motor 44 Controls the rollers that fold the paper. Fold Plate Motor 46 Controls the plate that makes the fold in the paper. Bottom Fence Lift Motor 47 Raises the bottom fence and stapled st ack to the correct fold position for the paper size. Punch Motor 48 Punches the holes in the paper. Paper Position Sensor Slide Motor 52 Controls side-to-side movement of the paper position sensor in the punch unit. Punch Movement Motor 57 Moves the punch from side to side.

Booklet Tray SM 43 B793 B793 Booklet Finisher 2.5 BOOKLET TRAY The sensor actuator arm [A] re sts on the top of the stack of stapled booklets as they are output to the lower tray. A flap depressor [B ] keeps the open ends of the booklets down. The front booklet tray full sensor [C] and r ear booklet tray full sensor [D] detect when the tray is full of booklets. ƒ The front booklet tray full sensor is mounted higher than the rear booklet tray full sensor. ƒ The booklet tray is stationary. When it becomes full, the stapling and folding job stops until booklets are removed from the tray. ƒ If the booklet tray is not installed (this is detected if the front and rear sensors remain OFF), the machine will not operat e in the booklet staple and fold mode. When booklet mode is selected, the tray full message appears on the operation panel. The combinations of the tw o actuators and two sensors w hen the actuator arm rises determines the number of booklets that t he tray can hold before the job stops. Tray full detection depends on the size of the paper and the number of sheets in one stapled and folded booklet. The condition detected by the machine ( Ready Full 1, Full 2, Full 3; see the illustration above) depends on the states of the sensors, as shown in the table below.

After a booklet is feed out, the fold roller mo tor stops the exit roller. The machine then monitors the tray full sensors every feed-out of a paper stack. The machine checks a certain condition, based on the si ze of the paper and the number of sheets in the booklet. Two examples are shown below the table. Tell the operators that the number of sheets that the lower tray can hold will vary greatly. - Lower Tray Full Condition Tables - A3 (DLT) Sheet 1 2 3 4 5 6 7 8 9 10 Full 1 15 Cnt - - - - - - - - - Full 2 - 3 Cnt 11 Cnt - - - - - - - Full 3 - - - 16 Cnt 12 Cnt 2 Cnt 3 Cnt 5 Cnt 6 Cnt 7 Cnt A4 (LT) Sheet 1 2 3 4 5 6 7 8 9 10 Full 1 15 Cnt - - - - - - - - - Full 2 - 8 Cnt 16 Cnt 19 Cnt 5 Cnt 2 Cnt 2 Cnt 2 Cnt 3 Cnt 4 Cnt Full 3 - - - - - - - - - -
Booklet Tray SM 45 B793 B793 Booklet Finisher - Examples - After the copier makes a booklet with 1 sheet of 11 x 17 inch paper, the machine checks every feed-out of a paper stack for the ‘Full 1’ condition. If the Full 1 condition occurs 15 times (‘ 15 Cnt’ in the table above), the machine detects that the tray is full. After the copier makes a booklet with 5 sheet s of A4/LT paper, the machine checks every feed-out of a paper stack for the ‘Full 2’ condition. If the Full 3 condition occurs 5 times (‘ 5 Cnt’ in the table above), the machine detects that the tray is full.
Jogger Unit B793 46 SM 2.6 JOGGER UNIT The jogger is used in corner-s taple mode and in booklet mode. For each sheet of paper when it arrives in the staple tray, the following is done. ƒ The jogger motor [A] drives the jogger fences [B]. ƒ The positioning roller solenoid moves the positioning roller [C] onto the top of the sheet. Then the lower transport motor turns on and t he positioning roller rotates to push the sheet of paper against the stopper (there are two stoppers: stopper L or stopper S the one that is used depends on the paper size, as we shall see later.) The jogger HP sensor [D] detec ts when the jogger fences are at home position (away from the stack). The staple tray exit sensor [E] detects if a jam occurs when the machine feeds the stack out at the bottom of the jogger tray.
