These errors appear to be a laser failure error. There are a few
suggestions out there for you to try on your own like the one on this
page from sharuel that worked for him.
It is unlikely you
can resolve this yourself, but to unplug the printer for 15 minutes,
and then plug it back and see if the error cleared. This can sometimes
be caused by power fluctuation, so if the printer is connected to a UPS
or powersurge protector, try to connect it directly to the wall.
Also here is
link to a page showing what the error message means and suggestions on
what to do which are basic steps related to the error message.
If all this fails, there is no other option but getting HP or a technician to service the printer.
