Scanner Transporter
The slide scanner transporter system consists of a 35 mm transparency holder, a transporter
stepper motor and a photo-sensor located on the front of the main controller PC board. Upon
command from the microcontroller, the transporter system drives the 35 mm transparency being
scanned through the scanner's illuminated scanning area while the lamp and optics projects and
focuses the image line-by-line onto the CCD sensor on the image sensor PC board.
The main controller PC board provides a transporter driver that receives signals from the
microcontroller. These signals directly drive the transporter stepper motor to its applicable
position during scanning and calibration. The transporter photo-sensor (U1) provides the
reference for properly positioning the transporter assembly.
Scanner Optics
The slide scanner optical system consists of a florescent lamp, a filter wheel (original SS35 and
SS35 ES up to serial no. B6xxxxxxD) or light tunnel (SS35 ES from serial no. B6xxxxxxE and
SS35 PLUS), and a lens block assembly (filter and lens). Figure 2-2 shows the scanner image
path.
