| media index
| Selects the media index from 0 to 15.
|
The sensitivity adjust defined by the copy of the media parameters where the copy is selected by the media index. When the host turns on the laser in preparation for a plot, the laser power is specified by the sensitivity, the area of a swath and the drum speed.
|
|
| Theoretically the sensitivity should be a constant for every media but experience has indicated that the sensitivity is head-dependent. The NVS parameter med <media index> sensitivity defines the constant for the media and the NVS parameter med <media index> sensitivityadjust defines a head-dependent adjustment percentage.
|
|
| Note that the thermal head does not access the sensitivity adjust; this field is used only by the host. This media parameter is defined by the thermal head because the exposure ( determined by the combination of the laser power and the drum speed ) is head-dependent.
|
|
| The NVS parameter med <media index> laserpower is the original method used to define the laser power. The NVS parameter med <media index> sensitivity and med <media index> sensitivityadjust is the preferred method used to define the laser power. The sensitivity is independent of the area of a swath and the drum speed.
