• When the ADF Is Closed
When the ADF is closed, the machine-side sensor goes ON as soon as it is closed to 30°
or lower [3], causing the machine to assume that the ADF is starting to close; 4 sec thereaf-
ter, the machine assumes that the ADF is fully closed [4].

Memo
Detecting the Size of an Original
The GP605 (iR600) is designed assuming that the ADF is fully closed 3 sec
after the machine-side sensor is ON. It compares the sates of the original
size sensors when the machine-side sensor goes ON and 3 sec thereafter to
identify the size of the original on the copyboard glass. If the user, there-
fore, does not close the ADF within 3 sec after the machine-side sensor
goes ON, the GP605 (iR600) can wrongly identify the size as being A3.
In the case of the machine, it uses 5 sec for the detection of original size
without affecting the first copy time (i.e., by making use of the 2 sec re-
quired by the fluorescent lamp to go ON).
