NovaJet 500/630/700 Series Service Manual
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 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.
Carriage Test - Prints 5 sets of 3 parallel lines to test the vibration
characteristics of the carriage assembly.
Color Test - The Color Test prints a wide swath of each 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.
