4.1.3 Roller/rolls spacing mechanism
A. Storage roller/rolls spacing mechanism
• The Storage Roller briefly stops when the first sheet of paper completes a switchback
sequence during a multi-print cycle in the Sort Staple mode. If, however, paper measures
217 mm or more in the FD direction, the leading edge of the second sheet of paper
reaches the Storage Roller before the roller stops turning. The Storage Roller is therefore
raised up to allow a given clearance from the Storage Rolls.
• The Storage Roller is spaced from the Storage Rolls as a cam is turned by the corre-
sponding motor.
B. Exit roller/rolls spacing mechanism
• Paper needs to be temporarily transported to the Finisher Tray in the Staple mode, which
makes it necessary to raise the Exit Rolls to provide a given clearance from the Exit
Roller.
• After the stapling sequence has been completed, the Exit Rolls are lowered and pressed
against the Exit Roller so that the paper can be fed out.
• The Exit Rolls are spaced from the Exit Roller as a lever is moved to the right and left by
the cam which is rotated by the motor.
