3. Document size detection
Document size detection by document set tray
When a document is set on the document set tray in the auto mode
of paper/copy magnification ratio selection, the document size is
detected to perform the auto selection function of paper and the copy
magnification ratio according to the detected document size.
When documents of different sizes are mixed and set on the tray, 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 determine the
document size.
The document size judgment is made after a certain time from when
the document set sensor (W0) detects the document.
