6-19 Printer Options
Using a Security Card
A security card allows the Operator Control and Administration menus
to be password protected, so only users who know the password can
change printer configuration settings. When a security card is inserted
to one of the card slots, the Installation menu appears in the printer's
configuration menu. See chapter 4, “Printer Configuration,” for com-
plete menu information.
▲ Caution: The printer must be off line (the Online/Offline 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.
1 Take the printer off line.
The Online/Offline indicator should be off.
2 Insert the security card.
You can use either slot,
but the card must be
inserted with the QMS
label side facing up. You
should feel the card snap
into place.
