MX-7000N  DSPF SECTION  C – 7

Size detection on the document tray
The document width is detected by the DSPF document width sensor (SPWS), and the document length is detected by the DSPF 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, documents of different sizes are mixed and set on the document tray, the largest size is detected.

To increase the document replacement speed, pre-feed of the second and the later documents is performed for documents of A4/Letter or
smaller sizes. Therefore, a clutch is provided for each transport roller to perform individual control. An electromagnetic brake is provided for
each transport roller in order to reduce loads to the motor in comparison with a mechanical brake.
