Diagnostics (Mode 2) - Error Log Viewing the Error Log The Error Log aids the Customer Engineer by providing a history of printer errors. It contains the 12 most recent errors. The most recent error is displayed in position 1, and the oldest error is displayed in position 12 (assuming 12 or more errors have occurred). If fewer than 12 errors have occurred, then the oldest error is displayed in the position before the empty log entries begin. Empty log entries are identified with an error number of 000. Occupied log entries contain the error number for the message that is displayed on the operator panel. For example, 925 is contained in the log when a 925 Service Error occurs. If an error occurs after the log is full, the oldest error in the log is discarded to make room for the new error. The printer stores identical errors in consecutive positions in the log. In other words, error log position N and position N+1 could contain the same error code if the same error occurs twice in a row. The following error messages are stored in the error log. • All 2xx paper jam messages • All 9xx service messages To view the error log, select the Display Log operation from the Diagnostics ERROR LOG menu. The entire error log cannot be displayed on a single screen. Four error log entries are displayed per screen. Therefore, the entire error log takes up 3 screens. To move Diagnostic Aids 3-37
