On HP Laser-Jet printers, a self-test page will be initiated by the
test.
If the “TEST” LED goes out and the “PASS” LED fails to light,
the printer’s IR port is not functioning correctly; check the
operator’s instructions included with the IR test tool.
To test the host computer:
1 Place the test tool on a table in front of the PC’s IR port.
2 Press the “computer Test button. The test tool will sequence
the LEDs.
If the “PASS” LED light, the test was successful, indicating that
communication with the printer’s IR port is functioning normally.
If the “TEST” LED goes out and the “PASS” LED fails to light,
the host’s IR port is not functioning correctly.
