Ideas for Using Printer Features
Note: For detailed information on
these features, see your on-line
User’s Guide
Secure Print Feature
 Ideal for printing confidential
documents on a network system.
Idea!
When printing special media, use this
feature to prevent documents being
sent by other clients on the network
from printing on your media:
• Create your document and store it in
the printer’s memory.
• Load the special media.
• Start printing the document by
accessing it through the front panel
(see page 19).
Proof & Print Feature
 Use Proof & Print to proof your
document before printing
multiple copies.
For the latest information and ideas
for your printer, check
my.okidata.com.
Overlays (Forms)
Note: Overlay elements must be
created in your software
application, then stored on the
printer’s hard drive using OKI
Storage Device Manager
before they can be used.
 Great for adding logos, addresses,
letterheads, etc., to your
document, in any combination.
Ideas!
User overlays:
• in place of pre-printed stationery.
• to create forms from pre-stored
modular pieces.
