2. ADF

[A]
When using the ADF, the machine can only detect the document width. Un-
like a copier's ADF, the machine cannot detect the document length, because
there is no length sensor.
As a result, the following copier functions cannot be used when using the
ADF, since these functions require the document length before proceeding.
•
Automatic paper selection
•
Erase border/center
The document sensor [A] and B4 width sensor [B] detect the document width.
•
When the document sensor is activated but the B4 width sensor is not,
the machine treats the document width as either A4 (210 mm) or Let-
ter/Legal (216 mm).
•
When both sensors are activated, the machine treats the document
width as B4 (256 mm).
The setting of system switch 0C bit 3 determines whether an International or
US paper size is detected.
