7-16 Troubleshooting
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.
