Aligning the Feeder
The Feeder is pre-adjusted to align perfectly with most individual
scanners. However, some scanners may have a drum that is aligned
slightly outside of the tolerance range of the Feeder. If the slide original
holder is not being drawn correctly into the scanner, then you may
need to adjust your Feeder alignment as described below. In most cases,
however, this is not necessary. Usually, you will need to do this just once
if at all.
Checking the Alignment
To check the alignment, mount the Feeder to your scanner and insert
the slide original holder as described in “Mounting the Feeder” on page
8. Then inspect the slide original holder to see if it sits perfectly centered
within the Feeder. If it is too far to the left or right, then the Feeder will
have difficulty loading the Feeder in or out of the scanner. It may also
have trouble monitoring the position of the holder, so you may get an
error claiming that the Feeder “can’t find the frame position”.
If possible, measure the distance on each side of the slide original holder
and calculate the correction needed to center it.
Correcting the Alignment
If the slide original holder is not centered correctly in the Feeder, then
use the procedure below to realign the Feeder.
If the feeder is currently mounted, then use the software-assisted
procedure to unmount the Feeder as described in “Unmounting the
Feeder” on page 15.
Inspect the back panel of the Feeder and locate the two nuts that hold
the feeder to its mounting plate, as illustrated below in Figure 13.
