NOTE: The length sensors L1 and L2 are used only for 230 V machines.

For other combinations, the operation panel will display "CANNOT DETECT ORIG.

The above table shows the sensor output for each original size. This original size

detection method eliminates the necessity for pre-scanning and increases the

machine's productivity.

However, if the by-pass feed table 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 a full A3 area,

disregarding the original size sensors. However, for each page, the data signal to

the laser diode is stopped to match the copy paper length detected by the

registration sensor. This means that copy time for the first page may be slower

(because of the longer time required for scanning), but it will be normal for the rest
