Parallel Port Test
This test performs a wrap around test between the printer parallel
port and the parallel port test connector.
This test requires a parallel port wrap plug. Install the wrap plug in
the parallel port before you start the test.
To run the test:
1. Turn the printer off and unplug the machine.
2. Attach the wrap plug to the parallel port (P/N 1319128).
3. Position the left edge of the printhead carrier at the center of the
third exit roller.
4. Turn the printer on.
The power light stays on if the test runs successfully. A failure occurs
if the power light does blinks. The test continues until power is
turned off. Irregularity of the blinking of the power light, is an
indication of an intermittent problem. This test should run for a few
moments to verify no intermittent problems exist.
