NOTE: The length sensors L3 and L4 are used only for 230V machines.
For other combinations, the message "CANNOT DETECT ORIG. SIZE" will
be displayed 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 cycle
and increases the machine's productivity.
However, if the by-pass feeder is used, note that the machine assumes that
the copy paper is lengthwise. For example, if A4 sideways paper is placed on
the by-pass tray, the machine assumes it is A3 paper and scans the full A3

area, disregarding the original size sensors. However, in this machine, for
each page, the data signal to the laser diode is stopped to match the copy
paper length detected by the registration sensor.
Original size detection using the ADF is described in the manual for the ADF.
