A menu that is not accessable to the operators can be activated in the

Continuous Test - The Continuous Test sends the printer into a test
loop that will perform a series of tests continuously. Powering
down and restarting the printer is the only way of exiting this
test loop.
The Continuous Test will first prime the cartridges, followed by
a serial port test, parallel port test, a fast deadband display and
a color calibration display.
The deadband and color calibration displays are used only as a
visual inspection of the operating condition of the printer. No
adjustments can be performed while in the Continuous Test
mode.
A loopback Test Cable is required to correctly accomplish the
serial and parallel port tests. Install both ends of the Loopback
Cable before running this test. The Loopback Test Cable is
listed in Chapter 6.
After completing the deadband display, the test will begin again
with the prime and continue until power is removed.
Fan #1 and Fan #2 Tests - Tests the operation of the fans on the
printer. Fan #1 Test (while depressed) turns on the power
supply cooling fan and the suction fan inside the platen on the
right side of the printer. Fan #2 Test (while depressed) turns on
the suction fan inside the platen near the center of the printer.
The 42 inch printer does not have this second suction fan,
therefore, the Fan #2 Test is disabled.
Legs Test - Tests the condition of the leg harness connections and
the components of the power feed and take-up system.
