Description
φ
SEL
High Resolution Mode
1200 dpi (Max.)
High level
Low Resolution Mode
600 dpi (Max.) (even line readout mode)
Low level
(1) High Resolution Mode
In this mode, both signals in even lines and odd lines can be read out. This mode enables 1200 dpi (Max.)
resolution with A4 size (210
×
297 mm, shorter side).
Please refer to
TIMING CHART 1-1, 1-2
and
2-1
.
(2) Low Resolution Mode
In this mode, only signal in even lines can be read out.
This mode enables 600 dpi (Max.) resolution with A4 size.
To use intermittent reset drive enable signal charges of adjacent pixels in even line to add at the charge to voltage
conversion area. Then it can achieve low resolution with A4 size such as 300, 200 or 150 dpi.
