View the event log at the control panel If the printer cannot print or move any paper, follow these steps to view the event log at the control panel: 1 Press [MENU] until INFORMATION MENU appears. 2 Press [ITEM] until SHOW EVENT LOG appears. 3 Press [SELECT] to show the event log. 4 Press [+] to scroll through the event log. 5 Write down the error messages. 6 Check the event log for specific error trends in the last 10,000 printed pages. 7 Ask the customer for any observed error trends. (For example, do jams tend to occur in a specific area of the printer?) 8 Record any specific error trends. 9 See table 32, "Printer messages," on page 193 and follow the recommended action. 10 If the control panel shows READY, OFFLINE, or POWERSAVE ON, go to the next section. If it shows any other message, see "Printer messages" on page 193. Print the event log The printer's internal event log stores the last 30 errors. To print the event log:
Press [MENU] until INFORMATION MENU appears.
Press [ITEM] until PRINT EVENT LOG appears.
Press [SELECT] to print the event log. Interpret the event log The event log is the key tool for troubleshooting printer problems. Figure 123 shows a typical event log. The event log shows the current page count at the top, left of the page. The printer's serial number appears directly to the right of the page count. The left column shows the error sequence number, with the most recent error listed first (the highest sequence number is the most recent error logged). The next column is the page count at the time of the error. The last column contains a short description of the error or the personality (PCL or PostScript) at the time of the error. The event log might record errors in a different format than the format that appears on the control panel. For example, if 50.1 FUSER ERROR / CYCLE POWER appears on the control panel, the event log shows a 50.02.01 error, in which the 02 signifies that two sensors were blocked. Likewise, when messages 13.1 through 13.9 appear on the control panel, the event log shows 13.0x.01 through 13.0x.09, where x= the number of sensors that were blocked in the printer. Note Whenever a 13.XX appears on the control panel, a good practice is to clear all jams from the printer and print the event log. If you cannot print the event log, you can still view it on the control panel. To interpret the event log:
Each individual entry in the log is called an "error," and all errors that occur at the same page count are called an "event." Read the recommended action for each error within an event to gain a clear picture of what took place during that event. Events usually conclude with a time-out or with no response from the printer (Error 66.XX in the event log) which requires a power cycle of the print engine.
Use the message column in table 32, "Printer messages," on page 193, to associate error messages in the event log with the control panel error messages. Follow the recommended action listed in the table for each error or event. 192 Troubleshooting Q1860-90918
