Engine Diag Performs function checks on the components whether they
operate normally or not.
Note: During Engine Diag test, other Service Diagnostics functions
cannot be performed simultaneously.
Sensor Test Tests the sensors and switches of the
printer.

Note: The Low/High values can be 0 to
99, and they can be incremented as the
sensor state changes. This value is
incremented up when a sensor or
switch is turned On from Off, which
