Symptom
When making multi-page enlargement in the digital art function, C3300(scan trigger input failure)
may appear.

Cause
When making multi-page enlargement, how many areas the original is divided into (2~36) in order to
read the image is determined based on a combination of original size and reproduction ratio. After
the start key is pressed, the developing process is done in the order of C->M->Y->BK, so the
scanning and returning operation is repeated by the scanner. The order of the area to be read starts
from the rear of the original scale side to the front, then to the trailing edge of the scanning direction
(If the area is divided into four, the order is as shown in the figure below). As the scanner returns
even after BK is developed, depending on original size and reproduction ratio it takes too long to
move the scanner to the scanning start position of the next area when the area is changed to the
scanning direction (Move from "2" to "3" in the figure above), which causes the error C3300.

changed so that the scanner will not return after developing Bk.
