- Stacking
Paper is sent to the staple tray by the alignment brush roller.- For paper of sizes which can go into the pre-stack tray (A4 SEF, B5 SEF, LT SEF): The top fence moves down and presses the leading edge of the paper to straighten the leading edge of the paper. When more than 50 sheets of paper are sent to the staple tray, the positioning roller presses the paper to prevent the paper from falling down.
- For paper of sizes which cannot go into the pre-stack tray: After the stapler tray entrance sensor turns off (A4 size paper: 55 to 65 ms after the trailing edge of the copy passes the stapler tray entrance sensor), the positioning roller motor is energized to push the positioning roller into contact with the paper. Then the positioning roller rotates to push the paper back and align the trailing edge of the paper against the stack stopper. The alignment brush roller guides paper to the stack stopper.
Jogging
Stacking straightens the rear edge of paper. Then jogging straightens the sides of the paper. At the start of a copy job, the jogger fences move 7.2mm from the width of paper and wait. When the rear edge of the paper passes the stapler entrance sensor, the jogger fence moves 3.7mm inward while stacking straightens the rear edges of the stack. Then the jogger fences move another 3.5mm inward to straighten the side edges. When jogging is completed, the jogger fences wait 7.2mm away from the width of the paper until the next operation.- A plate spring extends from the front and the rear edges to improve the straightening mechanism.
- Paper Holding
To staple up to 100 sheets of paper, the machine holds paper so that the edge of the stack that will be stapled is flattened. When the jogger returns to the home position, the stack plate motors operate the stack plates that hold the paper. When the next following sheet turns the stapler entrance sensor OFF, the stack plate motors turn ON to return the stack plates back to the home position. The home position is detected with the stack plate HP sensors. This process is done every sheet, so that the front and rear stack plates hold down the curled parts at the corners of the stack. The front and the rear stack plates cannot operate if the stapler is there, so they only operate when the stapler is not there. This is monitored every sheet. The central stack plate always operates regardless of the location of the stapler.
