Pod Test:
enables hidden menus for production development and testing. The method
for enabling these menus should be kept private from non-qualified end users and
operators. The functions that are enabled in these menus can cause serious impairment
to normal printer function if used incorrectly.
To enable the hidden menu options, use the following keystrokes:
U = Up D = Down
UUUU UDUD UUDD UUUD
When you have completed the necessary operations, reboot the printer (shutdown
and restart) to return the menu to the normal state.
Print Tests
Print Test:
the user selects one or more of the printheads to test, then the printer begins
printing with only those heads until canceled by the user.
Print Y Calibration Patterns
*Horizontal Dot Accuracy Test:
select two contrasting colors and print a series of fine
horizontal lines. Consistent color across the width and length of the print indicates proper
horizontal dot placement. Shifting colors indicate uneven dot placement. Similar to the
Horizontal Line Test but with additional controls.
*Vertical Dot Accuracy Test:
select two contrasting colors and print a series of fine lines.
Consistent color across the width and length of the print indicates proper vertical dot
placement. Shifting colors indicate uneven dot placement.
Ink System Tests
This submenu tests various functions of the ink system.
Air Valves:
operates each of the air pressure/vacuum valves individually.
Prime Ink Pumps:
From time to time one or more of the pumps may fail to draw ink
from its reservoir. This option steps an operator through repriming the pump to restore
normal operation.
*Ink Pumps: run each pump individually.
Ink/Air Thermistors:
displays the temperature measurements being taken by the ink and
air thermistor pairs in each of the master printheads. This is the same information that
can be seen in the Printer Status screens accessed through the Front Page button.
