What this message means
The code in an internal print server is
not valid. The printer cannot receive
and process jobs until valid code is
programmed into the internal print
server.
A request for a manual feed job has
been sent to the printer. The printer is
ready for insertion of a single sheet
into the manual feed slot.
The printer is trying to staple a print
job, but the stapler is empty.
The printer is trying to feed paper from
a source it detects is empty.
