• When the ADF Is Closed
The sensor in the host machine goes ON when it is brought down to 30° or less [3]. At this
time, the host machine assumes that the ADF is about to be closed; this state remains for 5
sec and then, the host machine assumes that the ADF has been closed [4].

Memo
Detecting the Size of Originals
• GP605
It is assumed that the ADF is fully closed 3 sec after the sensor in the host
machine goes ON. Based on this assumption, the state of the sensor when
the sensor in the host machine goes ON and the state of the original size
sensor 3 sec thereafter are compared to find out the size of the original
placed on the copyboard glass.
This also means that, if the user fails to close the ADF within 3 sec after the
sensor in the host machine has gone ON, the host machine can wrongly de-
tect the size of the original (wrongly assuming the presence of an A3/LGR
original).
• iR8500/iR7200
The iR8500 and iR7200 allows 5 sec for the detection of the size of origi-
nals to avoid affecting the first copy time (It take 2 sec to turn on the fluo-
rescent lamp).
