Major components of the original exposure system are as follows:
Item Function/Method
Exposure light source LED
Original scan In BOOK mode: Original scan is performed by moving the contact image sensor (CIS).
When ADF is used: Original stream reading is performed with the contact image sensor
(CIS) fixed.
Scan resolution 600 dpi (vertical scan) x 600 dpi (horizontal scan) (Color send: 300 dpi horizontal scan)
Gradation 256
Carriage position
detection Contact image sensor (CIS) HP sensor (SR401)
Magnification range 50% to 200%
Vertical scan direction:
Image processing is by image processor PCB
Horizontal scan direction:
BOOK mode:
Carriage movement speed change and image
processing by image processor PCB *1
ADF mode:
Original feed speed change and image processing by
image processor PCB *1
Lens Rod lens array
CMOS sensor Number of lines: 1
Number of pixels: Total 7488 (incl. 7176 effective pixels)
Maximum original scan width: 304 mm
CIS drive control Drive control by reader motor (M401)
Original size detection [1] BOOK mode:
Vertical scan direction:
Detection by reflection type sensor (AB/INCH)
Horizontal scan direction: Detection by reflection type sensor (AB/INCH)
[2] When ADF is used
Width:
Detection by original width sensor PCB in ADF
Length: Detection by photo sensor in ADF
*1 The control method depends on the magnification. For more details, refer to "Magnification Change".
