Initialization
methods The scanner can be initialized (returned to

a fixed set of conditions) in the following
ways:

Hardware
initialization

Software
initialization

When the scanner is turned on.
When the scanner receives a SCSI Reset signal from
the SCSI interface.

Optional Transparency Unit
Specifications

The transparency unit (B813152) allows you to scan positive
and negative transparent materials—35 mm slides, 35 mm

filmstrips, and film up to 8.5 × 11.7 inches in size. In addition

to four film guides, it comes with a reflective document mat
that allows you to alternate between scanning transparent
materials and normal reflective (paper) documents.
