Initialization methods

SCSI Scanner is turned on or receives a SCSI

Reset signal from the SCSI interface
(hardware initialization).
Scanner receives a SCSI Bus Device
message or an Esc @ command from the
software (software initialization)

USB Scanner is turned on or USB cable is

unplugged from the USB port on the
scanner (hardware initialization)
Scanner receives a Bus Reset from the
USB interface, or an Esc @ command
from the software (software initialization)

Optional Transparency Unit (B813182)

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

film or documents up to 8.5 × 11.7 inches in size. In addition

to four film guides, it comes with a reflective document mat
