Interpret the Event Log

	Interpret the Event Log
	The Event Log is the key tool in troubleshooting printer problems.
	Figure 7-3 shows a typical Event Log. The Event Log shows the
	current page count at the top left of the page with the printer’s serial
	number directly to the right of the page count. The left column is the
	error sequence number, with the error listed at the top (the highest
	sequence number is the most recent error logged). The next column
	is the page count at the time of the error, and the last column is the
	Personality (PCL or PostScript) column or the cause of the jam at the
	time of the error.
	The event log for early versions of the HP LaserJet 4000 series
	printer may record errors in a different format than the Control Panel
	display. For example, if 13.20 PAPER JAM is displayed on the Control
	Panel, the Event Log records error number 13.32.48 or 13.20.48.

Hint	Whenever a 13.XX appears on the Control Panel, a good practice is to
	clear 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:
	● Each individual entry in the log is called an “error,” while 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.
	● 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.
