8.8.8 Horizontal Registration Position Detection Operation
0009-3190
The machine executes home position detection of the duplexing horizontal registration sensor when the main power switch is turned on, when jam recovery
is started, or when the front cover is closed. The registration sensor goes on, and moves to the start position (A4 detection position).
When the paper moves from the duplexing feed assembly and reaches the duplex paper sensor (PS34), the horizontal registration motor (M16) goes on,
and the duplex horizontal registration sensor (PS31) stars to check the edge of paper while the paper stops at the duplexing repickup point and for each
duplexing session.
The machine checks the paper width indicated by the slide guide of the manual feed tray assembly and the cassettes size when the registration sensor goes
on, to determine the point at which detection is to be started (a point about 10 mm from the edge of paper assuming ideal movement of paper).
The start position is used as the point of reference, and the machine identifies the paper position taking into account the likely displacement based on the
number of drive pulses from the motor (1 pulse = about 0.16 mm).
F-8-47
*1: The edge of paper and the contact with the sensor are detected in the absence of the light-blocking plate.
*2: The start position (SP) varies as the paper edge position varies depending on the size of paper.
HP: start position of the duplexing horizontal registration sensor.
SP: start position of the duplexing horizontal registration sensor.
