10.9 PAPER REGISTRATION
Main motor rotation is transmitted to the timing belt [A] through a series of
gears. The timing belt rotate the relay gear [B] and then the registration roller
clutch gear [C]. When the registration clutch [D] is energized, the rotation of
the clutch gear is transmitted to the lower registration roller [E].
The registration rollers can be rotated by a knob in the front to ease misfed
paper removal.
The registration sensor [F], which is positioned just before the registration
rollers [G], controls the paper feed stop timing. The 1st paper feed clutch
stays on for 120 milliseconds and the relay roller clutch (2nd feed station)
stays on 144 milliseconds after the leading edge of paper actuates the
registration sensor. At the end of the period, the CPU turns off the 1st paper
feed clutch or the relay roller clutch. This delay allows time for the paper to
press against the registration rollers and buckle slightly to correct skew.
The CPU energizes the registration clutch 1.4 seconds after the Start key is
pressed. The registration rollers then feed the paper to the image transfer
section.
