3.5.1 Manual ID Control
When in manual image density mode, the user can select one of 14 manual
ID levels. For each level, the intensity of the light output by the exposure lamp
(as measured by the light sensor) is fixed. This is shown in the above graph.
For manual ID levels 2 through 7, the development roller bias also varies.
(See the section on development bias.)
