3. Document size detection
1) Document size detection with the document set tray
When documents are set on the document set tray in the auto selection
mode of paper/copy magnification ratio, the document size is detected
and paper and the copy magnification ratio are automatically selected.
When different sizes of documents are set, the max. size is detected.
The document width is detected by the document width sensors (W1,
W2, W3), and the document length is detected by the document length
sensors (L1, L2) to identify the document size. Judgement of the docu-
ment size is made in a certain timing after detecting the document with
the document set sensor (W0).
