Soft vs. Hard Reset

Resetting the printer returns it to a previous configuration. There are two kinds
of reset.

Soft Reset

A soft(ware) reset clears printer memory then loads the power-up
configuration into memory. (The procedure for saving configurations is
described in the Setup Guide .) It is called a soft reset because no hardware is
tested. All diagnostic and initialization tests are bypassed and memory is
simply refreshed with the power-up printer configuration.
Put the printer in the NOT READY state to do a soft reset:
1. Press the Stop key to put the printer in the NOT READY state.
2. Press the Stop + Enter keys.
The LCD displays "STANDBY...", "SOFT RESET" while the printer loads
the power-up configuration.

Hard Reset ("Cycle Power")

A hard(ware) reset is a power shutdown and restart that runs all initialization
and diagnostic routines. This is also called "cycling power."
1. Set the printer power switch to O (off).
2. Wait 15 seconds.
3. Set the printer power switch to 1 (on).
NOTE: A hard printer reset causes the +48V power supply (fans, motors,
etc.) to shut down in 1 to 5 seconds, depending on the amount of
memory installed on the controller board.
