MECHANICAL INITIALIZATION
During mechanical initialization, the following tests are performed:
1. The window sensor is checked. The initialization will not continue unless the win-
dow is in the ªdownº position.
2. The bail sensor is checked and the pen primer assembly is initialized.
3. The Y-axis is initialized. First the left stop is found, then the right (contact with the
cutter is made). The carriage then parks in the service station.
4. The pinch wheel position sensor is checked. If the optical sensor does not see light,
the plotter will act as if the pinch wheel lift lever is UP.
5. The media sensor is checked. If the optical sensor does not see light, the plotter will
act as if media is already present. A bad sensor could cause the plotter to try to load
media with media present or drop media out of the plotter during the rear edge search
(if sheet media is loaded at power ON). After the mechanical initialization is com-
plete, the plotter is placed into a ready state (either to accept media or to plot).
6. X-axis feedback operation is checked.
7. Remainder of DRAM tested.
