The Event Log may record errors in a different format than the Control Panel Display. For example, should a 50.1 FUSER ERROR / CYCLE POWER be displayed on the Control Panel, the Event Log will record a 50.02.01 error, with the 02 signifying that 2 sensors were blocked. Likewise, when a 13.1 through 13.9 are displayed on the Control Panel, the Event Log will record a 13.0x.01 through 13.0x.09, where x= the number of sensors blocked in the printer. Hint Whenever a 13.xx appears on the Control Panel, a good practice is to clear all the jammed paper from the printer and print the Event log. If you cannot print the Event Log, you can still display it on the Control Panel. Write the error next to the last error logged. The last error is the error at the top of the Event Log printout with the highest number in the left-most column. To interpret the Event Log: q Each individual entry in the log is called an "error," and all errors occurring at the same page count are called an "event". Read the Recommended Action for each error comprising an event to gain a clear picture of what took place during that event. Events usually conclude with a time-out, or no response from device (Error 66.xx in the Event Log) which requires a power cycle of the print engine. q Use the Event Log table in this section to associate errors in the Event Log with the Control Panel error message. Follow the Recommended Action listed in the table for each error or event. EN Troubleshooting the Printing System 7-15
