2.2.2 MIXED ORIGINAL SIZE MODE

This section explains what happens when the user selects mixed original size mode.
Because this ARDF is a sheet-through document feeder, the method for original document width
detection is the same as when the originals are the same size, but the document length detection
method is different. Therefore, the scanning speed is slightly slower.
Document length detection
From when the skew correction sensor switches on until it switches off, the CPU counts the
transport motor pulses. The number of pulses determines the length of the original.
Feed-in cycle
When the original size for the copy modes listed below cannot be determined, the image cannot
be correctly scaled (reduced or enlarged) or processed until the original's length has been
accurately detected. The length must be determined before the image is scanned.
