Service Manual • ScanMate 4000/5000 Edition 1 • January 1996
Four drum rotation speeds, six aperture settings and automatic focus
with software override are available.
The drum speeds change with resolution and the scanner will automat-
ically select an aperture. Higher resolutions demand slower rotational
speeds and smaller apertures.
Speed of rotation and aperture selection is adjusted automatically, (the
aperture can be overridden by the system software to smooth large
fields). The focus is adjusted automatically but can be overridden to
produce smoothing of rasterised originals.
Manual adjustment is achieved as follows:
• open photoshop plug-in.
• click on the options button.
• choose an aperture range from 1 to 6.
Note: 1 is the smallest value.
• choose a focus value from -500 to +500.
Note: positive (+) is away from the drum.
