All tests under the Diagnostics Menu should be performed by competent

PWM Test, Servo Cycle Test, Carriage Test, Color Test and Continuous
Test.
Servo “PWM Test” - Monitors the PWM (pulse width modulation)
signal applied to the servo motor from the driver on the MPWA
to check the amount of force required to move the Carriage.
The test performs three complete cycles of the carriage
assembly and lists the average PWM, the maximum PWM, and
the position of the carriage where the maximum PWM occured.
Servo “Cycle Test” - Tests the servo motor by moving the carriage
back and forth across the slide shaft. The number of cycles is
selectable and the available options are:
10
100
1,000
10,000
100,000
1,000,000.
