Controlling the Phase of the Crescent Roller
1.
Outline
If alignment was executed with the crescent roller in contact with the stack of sheets, the result-
ing friction against the roller causes the stack to move inappropriately (Figure 3-317). To prevent
this problem, the phase of the roller is identified and used to determine the timing of alignment.
The phase of the crescent roller is identified by the crescent roller phase sensor (PI12S). The
flag for the crescent roller phase sensor is mounted to the crescent roller shaft. The flag will leave
the sensor while the roller shaft rotates, turning the sensor ON or OFF, enabling the assumption that
the crescent roller is positioned at the opposite side of the stack (Figure 3-319). The alignment
plates are operated to correspond with this change in the state of the sensor.
