3.8.3 Functions
The following shows the construction and purpose of the scanning system:
1. Original glass
This is a glass for placing original. The light from the exposure lamp (EXP) is irradiated to the
original through this glass.
The ADF original glass is used when original is read with the Automatic Document Feeder. Original
is transported on the ADF original glass by the Automatic Document Feeder, and the transported
original is read under the ADF original glass by the carriage. Do not use such solvents as alcohol
when cleaning the surface of the ADF original glass, because it is coated so as not to be scratched
by originals.
2. Carriage-1
Carriage-1 consists of the exposure lamp (EXP), reflector, mirror-1, etc. It is driven by the scan
motor (M1) and scans an original on the glass.
