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.
