F:##### represents the number of times the test has failed (finished
with errors). Initially 00000 is displayed for #####. The maximum fail
count is 99,999.
The power indicator blinks indicating the test is in process. The
printer continually runs the same test until cancelled from the control
panel (by pressing Return or Stop).
Each time the test finishes, the screen is updated with the result. If
the test passes, then the Pass Count increments by 1. However, if
the test fails, then a signal error is displayed for approximately 3
seconds and then the Fail Count increments by 1.
Once the maximum pass count or fail count is reached, the test is
stopped, the power indicator is turned on solid, and the final test
results are displayed. Press Return or Stop to exit the test.
