A submenu containing a set of extensive tests that return measured
mechanism parameters for comparison against stated limits.

Collect 2 or 3 samples of the test data 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 printer 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.
To access the Check Menus enter Service Diagnostics and go to Check
Menu --> Check Activators Menu.
