Scanner unit
Original exposure and scanning are performed by the integrated scanner unit of LED, mirror,
lens and CMOS line sensor.
Light emitted from LED is re
fl
ected by the original and reaches the CMOS line sensor through
the 3 folding mirrors and 4 free curvature mirrors.
1. LED lamp unit
On LED lamp unit, the light is generated from the 2 LED lamp PCBs (LED chip: 48 pieces per
PCB).
Generated light is exposed to the original through the re
fl
ection plate.
2. Free curvature mirror
Scanner unit is equipped with the 3 folding mirrors and 4 free curvature mirrors.
Free curvature mirror has symmetric facet in main scanning direction and asymmetric facet in
sub scanning direction against the optical axis.
3. CMOS line sensor
CMOS line sensor scans the image per 1image line.
CMOS line sensor has 4 lines (R, G, B, BW). At B&W scanning, it uses 1 line (B/W) and uses
3 lines (R, G, B) at color scanning.
Error code
E301 (insuf
fi
cient light intensity)
-0001 The light intensity during front side shading is lower than the standard level
-0101 The light intensity during back side shading is lower than the standard level
