NOTE
• If a Duplexing Document Feeder is being used, it detects the size of the original.
• If a copy cycle is run with the Original Cover opened, the size of the original is deter-
mined when the Start Key is pressed.
3. Determining Original Size
• The copier determines the size of the original by the combination of the HIGH and LOW
outputs from the original size Detecting sensors SE1 to SE4.
• Even if an original is of an irregular size, the copier rounds the size to the nearest stan-
dard size.
