Document glass
Pattern 1
Original A: In the regular position and is
detected.
Original B: Is within the margin lines of area
2, so is detected as an original in area 2.
Original C: Placed in areas 1, 2, and 4, but is
within the margin lines of area 3 so is
detected as an original in area 3.
Pattern 2
Originals A and B are placed in area 1 in a
detectable state, but neither is detected
because they are treated as multiple
originals in one area.
Pattern 3
Original A: In the regular position and is
detected.
Original B: In area 2, but is not detected
because it touches the margin line.
Pattern 4
Original A: In the regular position and is
detected.
Original B: Not detected because it does not
fit into either area.
Pattern 5
Originals A and B cannot be detected
because both are placed in area 1, or they
are detected as a single original because
they are too close to each other.
