Chapter 3: Using the Operator Panel and Menus
Toner Darkness
(continued) When you first enter
Toner Darkness
, the operator panel displays:
Notice the periods (
.
) displayed across the second line of the operator panel. Each period
represents one of the numbers 1 through 10 from left to right. A symbol like a
v
or an arrow
points to the location of the
8
value, which is the factory default.
A minus sign (
-
) at the left end of the string of periods indicates you are scrolling to the lower
numbers in the string. A plus sign (
+
) at the right end of the string of periods indicates you are
scrolling to the higher numbers in the string. If you decide to change the setting to
6
, for
example, use
<Menu
to scroll back to the
6
.
As you scroll backward toward the minus sign ( - ) indicating lower numbers, notice the v or
arrow symbol moves on the operator panel as you press the <Menu button. It now appears in
place of the sixth period. Notice the numeral 6 displays next to the equal sign to indicate your
selection. A vertical bar ( | ) indicates the factory default of 8 . The vertical bar remains at 8
unless 8 is selected. Then, the arrow covers the vertical bar.
Press Select to select 6 as your current setting. The Saved message displays.
