This is a typical CCD scanner mechanism.

Point out the main components, as shown in the diagram in the manual.

The USA version contains two length sensors.

In this machine, there is an ADF exposure glass. In ADF mode, the scanner moves
below this glass and scans the original while the ADF feds it past this glass.
¾
In the Mojito and SP5, there was no ADF exposure glass. The ADF fed the
page onto the exposure glass, where it was scanned in the same way as for
book mode.
ˆ
There is also an optional anti-condensation heater for the scanner.
¾
The heaters for the paper trays and transfer unit are standard equipment.
