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 selec-
tion 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 sen-
sors (W1, W2, W3), and the document length is detected by the docu-
ment length sensors (L1, L2) to identify the document size. Judgement
of the document size is made in a certain timing after detecting the
document with the document set sensor (W0).
