3.2 Original Size Detection
The original tray width sensor, original length detection sensor, and original width detection sensors-1
and -2 work in combination to detect the size of originals.

3.2.1 Outline
When an original is placed on the original tray, the width of the original is detected by the positions of
the original width guides. Then the original width sensors -1 and -2 and the original length detection
sensor detect the size of the original being transported. Based on the detection result of these sensors,
the size of the original is finally determined.
3.2.2 Original tray width sensor
The original tray width sensor detects the width of an original placed on the original tray.
It is detected by the brush attached to the rack moving on the original tray width sensor, which is a
board with the different length of the patterns written.
This brush is moved as the original width guide is moved. Signals (TWID0S, TWID1S, TWID2S) are
opened and shorted to SG by this movement.
The combination of these short (= low level) and open (= high level) can determine the width of the orig-
inal.
Sizes detectable in combination of these open and short of the signals are as follows:
H (= high level): Open L (= low level): Short
