Notes.
1. Tint is the line scanning rate or integration time. Tint is determined by the interval of two start
pulses, SP. The integration time of 347msec is set at the factory. For additional comments, see note
(1) under Table 5, Recommended Operating Conditions.
2. fclk: main clock frequency.
3. Vpavg = å Vp(n)/1728.
4. Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%,
Where Vpmax = maximum pixel amplitude in the line scan and Vpmin = minimum pixel amplitude in
the line scan.
5. Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)) x 100%
Upadj is the non-uniformity in percent between adjacent pixels, Where Vp(n) is the n^th pixel in the
line scan.
6. Ud = Vdmax – Vdmin.
Vd = the average dark output level.
Vdmin is the minimum output voltage on a black document (LED is turned off).
Vdmax is the maximum output voltage on a black document (LED is turned off).
7. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 50 lp/in and Vmin: minimum output voltage at 50 lp/in,
where lp/in is the line pairs per inch.
