A. Document size detection
Size detection on the document tray
The document width is detected by the document width sensor
(SPWS), and the document length is detected by the document
length sensors (SPLS1, SPLS2). The document size is judged from
the document width and the document length as shown in the table
below.
When, however, mixed sizes of documents are loaded on the tray,
the maximum size is detected.
