Service error indications are a series of Power light flashes. There is
a pause between each series of flashes. If your printer has an error
indicator, locate the series of flashes in the
“Error Indicator Table”
on page 2-2 . and take the indicated action. Unplug the printer to
clear the error indicator.
The printer also logs the last occurring error. If you think it may have
an intermittent error, or the error indicator lights have been cleared,
you can retrieve the error:
1. Run the “Print NVRAM Contents” on page 3-6 The last error
appears at the bottom of the page.
2. To capture the next error in the error log, run “Clear NVRAM”
on page 3-5 to clear the error.
3. Run the “Print Test Page” on page 3-2 .” If no error appears,
go to “Power-On Self Test (POST) Sequence” on page 2-4 .”
