b) Output lines in sub-scanning direction
Scanning length L (1/1200 in) = 13200
Output resolution YR (dpi) = 400
Output line = [YR x L/1200 ] = [400 x 13200/1200 ] = 4400 (line) *
* Values under 0 in [ ] are omitted
The physical limitations of the Main Window Clipping at Flatbed (FB) and ADF reading are
illustrated in Figure 3.1 and 3.2 respectively.
NOTICE: This is not the guaranteed specification but the scanner may read the long document
which fits the following condition.
i) 0 < ULY + L ≤ 33072 (@1/1200 in.)
ii) L ÷ 1200 × YR ≤ 16383 line
iii)The memory installed is enough for reading.
