Chapter 5 - Troubleshooting and Maintaining the 6820 EEPROM Configuration Block Errors Errors related to an invalid block (diagnostic block) produce 13 beeps, and then the printer suspends. It continues to produce this symptom until the configuration block error is corrected. Configuration block errors may be caused by a flash write error or an incorrect printer configuration. Reset the printer to correct the error. If a reset does not correct the error, try reloading the printer control program using the Printer Configuration Utility or have the printer checked by a qualified service technician. Troubleshooting Using the Printer Self-Test Self Test Function Descriptions The self-test performs the following functions. • Boot Block Program Verification A CRC (Cyclic Redundancy Check) is performed on the boot block program. The calculated CRC is compared to the CRC embedded in the program module. • Control Program Verification A CRC is performed on the control program, which is loaded into writable flash program memory. The calculated CRC is compared to the CRC embedded in the program module. The results of this test are printed on the self-test report. • Font Module Verification A CRC is performed on the font modules, which are loaded into writable flash font memory. The calculated CRC is compared to the CRC embedded in the program module. Results are printed on the self-test report. • A2D Check Current reading of the A2D sources are performed, and the results are printed on the self-test report. • Nonvolatile Diagnostic Memory Verification A CRC is performed on the area of the nonvolatile diagnostic memory that has a CRC over it. Results are printed on the self-test report. 6820 Series 80-Column Printer User Manual 83
