Paper Feed Unit
6.4.1.6.8 Paper Take-Up Roll
• Since the Paper Lifting Plate is raised at all times by the Paper Lifting Springs, paper is wedged in the
mechanism when the cassette is slid out of the machine if the Paper Take-Up Roll is round in shape. So
the roll is semicircular and the circular part of the roll is positioned on top at times other than take-up.
For the purpose of explanation, we call this position of the Paper Take-Up Roll the "retracted" position.
• The Paper Take-Up Roll is grooved to keep good friction under heavy loading.
• In each of the Fixed Paper Size Cassette and Universal Cassette, there are two Paper Take-Up Rolls
mounted.
• When the Take-Up Solenoid is energized, it causes the spring tension to bring the drive gear into mesh
with the clutch gear. This results in the drive being transmitted to the Paper Take-Up Rolls.
