Use the component test to exercise individual parts one-at-a-time, so that you can determine the
cause of noise inside the MFP.
To start the test, select one of the components. The test will run the number of times specified by
the Repeat option. You might be prompted to remove parts from the device during the test. Press
the Stop button to abort the test.

Print/Stop Test
Isolate faults by stopping the device during the print cycle and observing where in the process the
image degrades. To run the test, specify a stop time and execute a Paper Path Test so that you
can specify simplex, duplex, output destination, and multiple page printing.
NOTE This test starts counting when the page activates the TOP sensor (SR5) and
therefore does not test the HCI. To test the HCI, you must print multiple pages from the HCI
and formulate a strategic stop time.
See Table 3-18 Print/stop test time values (simplex print jobs) on page 73 or Table 3-19 Print/stop
test time values (duplex print jobs) on page 74 in this section to determine Print/Stop Test stop time
values.
