Servo PWM Test - Monitors the PWM (pulse width modulation)
signal applied to the servo motor from the driver on the
MPCB to check the amount of force required to move the
Carrier. The test includes three complete cycles of the
carrier assembly and lists the average PWM, the maximum
PWM, and the position of the carrier where the maximum
PWM occured.
Servo Cycle Test - Tests the servo motor by moving the carrier
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.
Carriage Test - Prints 5 sets of 3 parallel lines to test the
vibration characteristics of the carrier assembly.
Color Test - The Color Test prints a wide swath of color (total of
four) to test for banding. The test is selectable in the amount
of ink that is to be printed. The available are: 10%, 25%,
35%, 50%, 65%, 75%, and 100%.
Continuous Test - The Continuous Test sends the printer into a
test loop that will perform a series of tests continuously.
Powering down and restarting the printer is the only way of
exiting this test loop.
