2. Technical Explanation Controls Paper inside a cassette is lifted up by the Lifter Plate. The Lifter Plate is lifted up by rotating the Cassette 2 Lifter Motor (M104). When the Cassette 2 Pickup Roller comes into contact with the paper surface, the Cassette 2 Pickup Motor (M102) rotates to pick up the surface layer paper, and the Cassette 2 Feed Roller and Cassette 2 Separation Roller feed only 1 sheet of paper to the feed path.
2. Technical Explanation *2: Presence of the cassette is detected when the size switch is pressed. (When none of the switches are pressed, it is judged as "no cassette".) Size Plate Cassette Size Switch Link Arm Guide Plate Paper Level Detection Control Paper level inside the cassette is detected by the sensors shown in the following table.

2. Technical Explanation Cassette Paper Sensor Cassette Paper Surface Sensor Paper Paper Cassette Paper Level Sensor Paper Detection Control Paper is detected by the Cassette 2 Size Detection Switch, Cassette 2 Lifter Sensor and Cassette 2 Paper Level Sensor. The absence of paper is notified when the Cassette 2 Paper Level Sensor is turned ON at the time the Cassette 2 Size Detection Switch is turned ON (it is detected that the cassette is in the host machine) and the Cassette 2 Lifter Sensor is turned OFF (the Lifter Plate is raised to the pickup position).
2. Technical Explanation Lifter Control When the cassette is set, the Cassette 2 Lifter Motor rotates to raise the Lifter Plate. Then, the paper is raised to the position to be picked up. Registration Control It is a control to align the image on the ITB with the paper at a specified timing. Based on the leading edge detection by the Pre-Registration Sensor, the following 2 controls are used: •...
2. Technical Explanation Image Registration PS04 Roller Cassette 2 Size Mismatch Detection Control Whether the size is mismatched is determined by paper length. The time a sheet of paper passes through the Pre-Registration Sensor is converted into distance. Then, the calculated distance and the paper size detected by the Cassette 2 Size Detection Switch are compared.

5. Adjustment 3. Loosen the Fixation Screw. 4. Move the Adjustment Plate to the left or right according to the scale value checked in step 3. As the Adjustment Plate is moved toward the left of the machine by 1 scale mark, the left edge margin is increased by 0.5 mm. 5.
5. Adjustment 6. Return the cassettes to their original positions. NOTE: If you are concerned with the difference in level of the cassettes after mechanical adjustment, adjust it by loosening the 2 screws. 7. Copy from the cassette, and check that the left edge margin is within 2.5mm +/- 1.5mm. Cassette Left Edge Margin Adjustment (1st Side: Software Adjustment) Copy from the cassette, and check that the left edge margin is within 2.5 +/- 1.5mm (in the case of LTR/LGL: 4.2 +/- 1.5 mm).
