(Conventionally, the correction has been made immediately before the start of actual scanning) This function takes effect in copying. Making the correction during standby may shorten the preparation time for copying. NOTE: Do not access these selectors. • Selector 7: Home position of the CCD unit This selector determines whether the home position of the CCD unit should be the CCD lock position or the location of the white-level reference film (attached to the inside of the scanner top cover). If the location of the reference film is selected, the CCD unit will not return to the lock position so as to shorten the travel time, decreasing the preparation time for copying. 46

Selectors
1
through
3:
Delay
time
from

the
ADF

in
These
selectors
determine
how
long
the
ADF
will
delay
automatic
drawing
-in
of
documents
(to
the
scanning
standby
position)
after
you
set
them
in

as
well
as
determining
whether
or
not
the
ADF
automatically

Selectors
4
through
6:
Periodical
correction
intervals
of
the
reference
voltage
applied
to
white
level
compensation
for
document
scanning,
during
standby
These
selectors
set
the
correction
intervals
(in
seconds)
of
the
reference
voltage
to
be
applied
to
white
level
compensation
for
document
scanning
during
standby,
as
well
as
determining
whether
or
not
the
controller
makes
the
reference
voltage
correction
during
standby.
(Conventionally,
the
correction
has
been
made
immediately
before
the
start
of
actual
scanning)
This
function
takes
effect
in
copying.
Making
the
correction
during
standby
may
shorten
the
preparation
time
for
copying.
NOTE:
Do
not
access
these
selectors.
Selector
7:
Home
position
of
the
CCD
unit
This
selector
determines
whether
the
home
position
of
the
CCD
unit
should
be
the
CCD
lock
position
or
the
location
of
the
white
-level
reference
film
(attached
to
the
inside
of
the
scanner
top
cover).
If
the
location
of
the
reference
film
is
selected,
the
CCD
unit
will
not
return
to
the
lock
position
so
as
to
shorten
the
travel
time,
decreasing
the
preparation
time
for
copying.
