CIS: moves to point of original detection
xenon lamp: off

F-5-19
3) Copyboard Cover Closed (15 deg C or more, less than 25 deg C )
a. External Light Detection
The machine executes an external light search.
F-5-20
b. Size Detection in Sub Scanning Direction
The copyboard cover sensor identifies a "closed" state.
CIS: at point of original detection
xenon lamp: off
original sensor: on
F-5-21
4) Copyboard Cover Closed (less than 15 deg C)
c. Size Detection in Main Scanning Direction
The machine turns on the xenon lamp inside the CIS, and uses the CCD inside the CIS to check the reflected light.
CIS: at point of original detection
xenon lamp: on
original sensor: on
F-5-22
5) Copyboard Cover Fully Closed
After the copyboard cover sensor has identified a "closed" state, the machine checks for a change in the output level of the original sensor (CCD point of
detection) for 3 sec. If there is no change in the level of output, the machine identifies the condition to indicate the presence of an original.
The machine uses combinations of changes in the levels of 6 locations to identify the size of the original:
F-5-23
6) Standby (in wait for a press on the Start key)
