Paper Feed Drive Mechanism
Figure 8
The feed roller [A] is located above the upper tray bottom plate [B], and the friction pad [C]. It al-
lows only one sheet to feed from the paper tray. They are controlled by the paper feed clutch [D].
The registration sensor detects the leading edge of the paper and synchronizes paper feed with
the activation of the laser diode to write the image on the OPC drum.
