The OPC belt sensor [A] is above the top
left corner of the OPC belt. The OPC belt
sensor is a reflective photosensor and finds
the markers [B][C] on the left end of the
OPC belt. The controller uses the signals
from the OPC belt sensor to calculate the
position of the horizontal joint line [D] on the
OPC belt. The copier does not use the area
around this line to make latent and toner
images.
