NOTE: L: Lengthwise, S: Sideways, O: Paper present, X: Paper not present
For other combinations, "Cannot detect original size." shows on the operation
panel.
The above table shows the outputs of the sensors for each original size. This
original size detection method eliminates the necessity for a pre-scan and
increases the machine's productivity.
However, if the by-pass tray is used, the machine assumes that the copy paper is
lengthwise (L). For example, if A4 sideways paper is placed on the by-pass tray,
the machine assumes it is A3 paper and scans a full A3 area. Information from the
original size sensors is disregarded.
Refer to the ARDF manual for more information on original size detection with the
ARDF.
6.3.4 ANTI-CONDENSATION HEATER
The anti-condensation heater is available as an optional unit. The anti-
condensation heater prevents condensation on the mirrors. Condensation can
occur when the scanner unit is moved from a cold room to a warm room, for
example. Condensation can cause abnormal images.
