Power On
The plotters automatically perform a series of internal self tests and mechanical initialization sequences whenever the user switches the plotter on. These are completed after about 30 seconds. If a failure occurs, an error is indicated on the front4panel LEDs. You can perform a failure analysis by interpreting the LED error code. (Details later in this chapter.)
PowerOn Self Test
The power4on self test does the following:
1Initializes the servo processor.
2Initializes the main processor .
3Tests communication between the main processor and the servo processor.
4Tests the ROM checksum.
5Causes the main processor to initialize certain firmware modules and communicate with the carriage processor.
6Tests the EEROM checksum.
7Tests the servo4processor transfer buffer and interrupt4tracking abilities.
8Tests the communication between the processors again.
9Tests the carriage ASIC.
10Begins mechanical initialization of the plotter.
