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.
