NOTE: L: Lengthwise, S: Sideways, O: Paper present X: Low
For other combinations, "CANNOT DETECT ORIG. SIZE" will be indicated on the
operation panel display.
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, note that 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,
disregarding the original size sensors.
