Clearable Warnings
A clearable warning indicates a transient condition in the
printer. The printer continues on line while the message is
displayed in place of 00 READY. A clearable warning appears each
time the printer alters resolution or page protection (this causes
reconfiguration of memory), or aborts a job due to an invalid or
uninstalled personality, or insufficient memory. Clear the
message by pressing [Shift] + [Continue] (or Go for the LaserJet 5).
