Chapter 5 - Troubleshooting and Maintaining the 6820 • Nonvolatile Diagnostic Memory Update The nonvolatile diagnostic memory is updated from the nonvolatile diagnostic memory data shadowed in memory. Performing a Printer Self-Test Initiating a Self-Test • While the printer is idle or in Suspend mode, press the Line Feed and Set Page buttons simultaneously to start a self-test. Terminating Self-Test • Press the Line Feed and Set Page buttons simultaneously to manually terminate a self-test. Running the Self-Test Perform a self-test to verify printer functions, and provide reporting of printer diagnostics. The self-test performs a series of internal diagnostics and prints the results. When the self-test begins, the beeper sounds for half a second and all LEDs turn on for half a second. A self-test is equivalent to a warm start. Both are performed when you simultaneously press Form Feed and Set Page buttons on the control panel for a few seconds. Release the buttons when the printer beeps and all indicators are lit. If you press the buttons for too long, the selftest will not happen and the printer will form-feed one page. As the self-test progresses, the indicator lights change. Internal tests are performed and a two page report is printed. The report provides helpful information in diagnosing and troubleshooting problems. Understanding the Self-Test Report The self-test report is divided into sections. For sample printouts, see "Sample First Page of the Self-Test" on page 87 and "Sample Second Page of the Self-Test" on page 88. All other values are informational only. Remember that these values are cleared after the self-test. • The printer model number is given on line 1 (first line). This identifies the printer type used, in this case the 6820. 84 6820 Series 80-Column Printer User Manual
