SELECTION OF RESOLUTION MODE
The
μ
PD8882 has function of two readout modes, High Resolution Mode and Low Resolution Mode. These two
modes can be selected by
φ
SEL switch.

High Resolution Mode
2400 dpi (Max.)
High level
Low Resolution Mode
1200 dpi (Max.) (odd 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 2400 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 odd photocell arrays can be read out.
This mode enables 1200 dpi (Max.) resolution with A4 size.
To use intermittent reset drive enable signal charges of adjacent pixels in odd line to add at the charge to voltage
conversion area. Then it can achieve low resolution with A4 size such as 600, 300 or 150 dpi.
