Extended Power!On Self Test
Perform the extended power5on test whenever the plotter passes the normal power5on test, but does not function properly.
To begin the extended power5on test, perform the following procedure:
Switch the plotter off.
Access
Cartridges
While holding the Access Cartridges key down, switch the plotter on.
Once the Busy LED lights up, release the Access Cartridges key.
As well as carrying out the normal power5on tests, the extended power5on test does the following:
Tests the processor5support5ASIC motion control circuitry. (These circuits control the media and carriage motors.)
Tests the swath RAM.
Tests the communication link between the cartridge5interface ASIC and the carriage ASIC.
4Tests the available DRAM not being used by the system. (The length of this test is dependent on how much DRAM is installed.)
5Begins mechanical initialization of the plotter.
Mechanical Initialization
The automatic mechanical initialization of the plotter begins at the end of the power5on test. The initialization procedure does the following:
Checks the window sensor.
Locates the initial position of the stepper motor.
Initializes the carriage axis (Y5axis).
4Ejects any loaded sheet of media.
5Checks the pinch5arm sensor.
6Checks the media sensor.
7Sets the plotter to accept media.
8Tests the remainder of the DRAM.
