Check Menu / Activators Definition Tables
The Check Menu contains a set of extensive tests that return measured mechanism
parameters for comparison against stated limits. Refer to the table associated with
each test for their normal operating ranges. In cases where insufficient baseline data is
available, the results have been left blank. All results from tests that move paper
through the system were collected using 24 lb. Bond paper.
Note
Often, just running the test will exercise a position of the sytem and provide
useful motions for observation. Also, collecting 2 or 3 samples of the test data
is recommended before deciding on a course of action. Many of the tests rely
on mechanical positions and slight changes can effect the results. Ensure that the
system is not out of paper, ink or maintenance kit life. The diagnostics routines
are not designed to address all of these conditions consistently.
If a test result differs significantly from the typical values defined in the
following tables, check the entire system containing the problem component to
ensure a problem within the system is not influencing the test results.
The Check All selection will run all check tests, taking 1.5 hours to complete and is
not for use by field technicians.
