This appendix shows how the status panel behaves when the printer is out of
paper, when there’s a paper jam, and when it’s time for routine maintenance.
Occasionally the printer may have a serious problem that cannot be fixed with
routine maintenance procedures. When such a problem occurs, the printer
will stop working, and the lights on the status panel will blink in patterns that
are meaningful to trained service personnel. If you take time to notice which
lights are on and report this on the telephone to an Apple-authorized service
provider, it will assist him or her in diagnosing and fixing the problem.
