Print Test Page
You can run the Print Test even if the printer is not attached to a
computer. Use this test to check print and graphics quality and the
version numbers of printer microcode. This test prints from the user-
selected default paper tray.
To run the Print Test:
1. Turn the printer on.
2. Select [MENUS].
3. Select [TESTS MENU].
4. Select [Print Test Page].
5. Select either [Single] for one page or [Continuous] for continu-
ous test pages.
6. Select [Stop] when you want the continuous test to end.
Print Test with RIP Board Removed
Most meter measurements required during printer service will be on
the engine board connectors, which are inaccessible with the RIP
board in place. The printer has a service mode which allows you to
test the printer without the RIP board installed. This verifies that the
motors, sensors, printhead, and electrophotographic process are
working correctly. In this mode, the operator panel has minimal func-
tion; service codes are not displayed and most error-handling is dis-
abled (during normal operation these functions are handled by the
RIP board).
Remove the RIP board and the inner EMC shield together and
power on the printer. The operator panel has one button active which
starts and stops the print test. The test consists of horizontal lines
spaced about an inch apart down the page. This is a continuous
print test; to print a single page press the start button twice.
