NovaJet 800 Series Service Manual

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 ink for the slot selected to test for banding and ink delivery system pressure. The test is selectable in the density 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 or selecting RESET is will exit this test loop.

The Continuous Test will first prime the cartridges, followed by a serial port test, parallel port test, a fast deadband display and a color calibration display.

The deadband and color calibration displays are used only as a visual inspection of the operating condition of the printer. No adjustments can be performed while in the Continuous Test mode.

A loopback test cable is required to correctly accomplish the serial and parallel port tests. This part of the test is not necessary to perform because the serial port is not used and the parallel port can be tested using the E-Connect TEST button. The TEST button on the E-Connect assembly on the rear of the printer when depressed quickly causes a Semi-Circular Nook Test pattern to be printed. This will effectively test the parallel ports (E-Connect and Main PWA parallel port).

After completing the deadband display, the test will begin again with the prime and continue until power is removed.
