The security card allows the Operator Control and Administration
menus to be password protected, so that only users who know the
password can change printer configuration values. When a security
card is installed, the Installation menu appears in the printer's config-
uration menu. See chapter 4, "Printer Configuration," for complete
configuration menu information.
Caution : The printer must be off line (the Ready indicator must be
off) before you insert or remove a security card. Press the Online/
Offline key once to take the printer off line. If you forget to take the
printer off line before you insert or remove a security card, turn the
printer off and back on again to regain access to the data stored in
the printer's memory.
A security card uses the same PCMCIA slot as a font card. The card
slot is located on the back of the printer next to the optional I/O port.
Use a security card as follows:
1 Take the printer off line.
The Ready indicator must be off.
2 With the label facing the optional network interface port,
insert the security card into the PCMCIA card slot.
