4049-XXX Token Ring Ethernet 10Base2 Ethernet 10BaseT LocalTalk 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 userselected 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 function; service codes are not displayed and most error-handling is disabled (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. Diagnostic Aids 3-18
