6.4.1.6.7 Paper Separating Mechanism

• Each cassette has fingers that function to separate the top sheet of paper from the rest of the paper
stack at paper take-up. The fingers are fitted to the right front and rear corners of the cassette. When
the Paper Take-Up Roll starts turning to take up the top sheet of paper, its turning force is directly
transmitted to the top sheet of paper as it is in direct contact with the Paper Take-Up Roll. That force
overcomes the block of the fingers, causing the top sheet of paper to ride over the fingers and be fed
out of the cassette into the machine.
• The collars and mylars placed on both sides of the Paper Take-Up Roll restrict the length of the loops
that form in the paper at the fingers, helping the paper edges to easily slip out of the fingers.
• As to the second sheet of paper, the paper transport force obtained through friction with the top sheet of
paper is weak and does not allow the second sheet of paper to ride over the block of the fingers.
Hence, the second sheet of paper remains stationary with the rest of the paper stack in the cassette.
• When there are only two sheets of paper left in the cassette, the bottom sheet can be fed with the top
one if the friction of the Paper Lifting Plate is weak. The Friction Plate affixed to the Paper Lifting Plate
prevents this from happening.
