Getting to know the 8825/8830 DDS
The Scanner (continued)
The Top Cover opens to allow access to the Document Drive Rolls and the
Document Hold-down Guide.
The Document Hold-down Guide may be lifted out and removed for periodic
cleaning and for the cleaning of the Platen Glass underneath. The guide
serves two purposes: it helps guide the document through the scanner, and
it serves as a target of known reflectivity during calibration of the scanner’s
cameras. This calibration, known as
normalization, automatically takes
place when the scanner is switched on. Therefore, the guide must be
installed before the Scanner is switched on and must be in place during
operation.
During normalization, the Scanner will not accept inserted documents.
