 CIS model
The automatic document feeder (ADF) of the CIS model consists of the pick-up roller,

For further details on the sensors, see 3.6 Sensors position.
Fig. 2-10
The duplex scanning mechanism allows you to use the following two types of scanning,
“ADF scanning” and “document glass scanning”. These two scanning methods are
switched depending on whether the document front sensor 1 detects the document or not
when starting scanning.
However, in the case of the CCD model, there is the case that the “document glass
scanning” is given priority to over by a state of the document cover sensor (described
later).
