SCANNING
B234/B235/B236/D101/D102/D103 6-32 SM
Two xenon lamp (30W, 57,600 lux) as the exposure lamp [4] illuminates the
original. Two lamps reduce the occurrence of dirty background caused if there is a
gap between the original and the exposure glass. The two lamps also improve
color registration for color scanning.
The image is reflected onto the CCD [11] (600 dpi resolution) via the 1st, 2nd, and
3rd mirrors, and through the lens [13].
The CCD (10 μm 600 dpi, 4 ch, 3-line) can scan in color as well as black and white.
The scanned color documents can be used with Palm (Auto Document Link, Desk
Top Editor for Production, Print Job Manager Professional) or with Scan-to-Email.
The lens, CCD, and SBU are in a single unit, the lens block. The optical axis, focus,
and MTF are pre-adjusted, so this lens block requires no adjustment in the field.
The 1st scanner consists of the exposure lamp [4], the lamp regulator [7] and the
1st mirror.
