Helpful Hints
This section summarizes the features and capabilities directly
connected to saving money and time.
Details for these features and capabilities are provided in
other sections of this document.
You may want to use some of our Helpful Hints when
working with your machine.
Your printer has many features and capabilities that will help
you
• save money
• save time
• operate the machine

Saving Money
Saving Money: Forms Tear-Off
The Forms Tear-Off feature allows a printed page (rear feed,
continuous form) to be torn off without wasting paper or
adjusting the printer.
Forms Tear-Off automatically moves the paper from the
initial printing position (print start position) to the tear-off
position, after a time interval (which you select through the
menu).
The top of the page (perforation) is even with the tear bar.
The tear bar is located under the clear top of the access cover.
Paper remains in the tear-off position until the printer
receives more data. Then, the paper moves back down for
printing (retracts to the initial print position).
When printing stops, the paper will advance to the tear-off
position.
This feature is normally turned off.
Forms Tear-Off and the Top of Form settings interact.
For more information, refer to “UsingYour Printer, Forms
Tear-Off and UsingYour Printer, Top of Form.”
Saving Money: Draft Mode
When printing drafts of documents, use either the High Speed
Draft or Super Speed Draft mode. These modes use less ink
than the Utility or Near Letter Quality Modes, thus extending
the life of your ribbon. The draft modes also print at high
speeds, reducing the time required to complete a print job.
For more information, refer to “UsingYour Printer, Print
Quality.”

Saving Time: Draft Mode
When printing drafts of documents, use either the High Speed
Draft or Super Speed Draft mode. The draft modes print at
high speeds, reducing the time required to complete a print
job. These modes also use less ink than the Utility or Near
Letter Quality Modes, thus extending the life of your ribbon.
For more information, refer to “UsingYour Printer, Print
Quality.”
Saving Time: Paper Park
Your printer’s paper park feature allows you to print a single
sheet (cut-sheet) page without removing continuous feed
paper from the printer.
For more information, refer to “UsingYour Printer, Paper
Park.”
Saving Time: Moving Through the Menu
When the printer is in Menu Mode, you can move forward or
backwards through the menu.
To move forward, press GROUP, ITEM, or Set, whichever is
appropriate.
To move backward, press and hold SHIFT, then GROUP,
ITEM, or Set, whichever is appropriate.
For more information, refer to “UsingYour Printer, Menu
Mode.”

The first line prints at the red line of the plastic paper shield
(1) on the printhead.
The Top of Form and Forms Tear-Off settings of your printer
interact.
How you set the Top of Form depends on the status of the
Forms Tear-Off menu setting.
For more information, refer to “UsingYour Printer,Top of
Form(TOF).”

Operation Tips
Operation Tip: Top of Form
!If you turn the platen knob when the printer is turned on, you will cause the Top of Form to mis-align. Always
turn the printer off before turning the platen knob!
!Always determine the status of the Forms Tear-Off menu setting BEFORE setting the Top of Form. Refer to
“UsingYourPrinter, Top ofForm, FormsTear-Off
Status(ON orOFF).”
Top of Form sets the print start position for the printer. It is
adjustable in increments of 1/144 of an inch. The amount of
adjustment is limited to avoid paper jams.
The Top of Form may be left at the factory default (1 inch),
changed for a single print job, or set to a new (permanent)
default.

Operation Tip: Turning the Platen Knob
!If you turn the platen knob when the printer is turned on, you will cause the Top of Form to mis-align. Always
turn the printer off before turning the platen knob!
Operation Tip: Control Access to the
Printer
You can control access to the printer by changing the setting
for the Operator Panel Function (in the Menu).
When the Operator Panel Function is set to Full Operation
(the factory default), all keys on the front panel operate.
When the Operator Panel Function is set to Limited
Operation,the PRINTQUALITYand CHARACTER PITCH
keys don’t work. This prevents these settings from being
changed from the control panel when several people are
using the printer.
For more information, refer to “UsingYour Printer, Menu
Mode, Menu Settings Table, Setup, Operator Panel
Function.”

• Your printer has a grounded, 3-prong plug as a safety
feature, and it will only fit into a grounded outlet. If you
can not plug it in, chances are that you have an older, non-
grounded outlet. Contact an electrician to have it
replaced with a grounded outlet. Do not use an adapter to
defeat the grounding.
• To avoid damaging the power cord, do not put anything
on it or place it where it will be walked on. If the cord
becomes damaged or frayed, replace it immediately.
Installation
Installation Hints
• Read the setup and operating instructions in this
document carefully. Be sure to save this document for
future reference.
• Read and follow all warning and instruction labels on the
printer itself.
• Place your printer on a firm, solid surface. If you put in on
something unsteady, it might fall and be damaged. If you
place it on a soft surface (such as a rug, sofa, or bed) the
vents may be blocked, causing it to overheat.
• The printer must be installed near a power outlet which
will remain easily accessible.
• Be certain that your power source matches the rating listed
on the back of the printer. If you are not sure, check with
your dealer or with your local power company.

20 Microline 320/321 Turbo

• If you’re using an extension cord or power strip with the
printer, make sure that the total of the amperes required by
all the equipment on the extension is less than the
extension’s rating. Generally, the total ratings of all
equipment plugged into any one power line should not
exceed 15 amperes. Don’t exceed this unless you know
that the power line your equipment is plugged into has a
rating above 15 amperes.
• To protect your printer from overheating, make sure no
openings on the printer are blocked. Do not put the printer
on or near a heat source, such as a radiator or heat register.
If you put the printer in any kind of enclosure, make sure
it is well ventilated.
Installation Overview
To install your new printer, follow the instructions from the
“Installation, Installation Location” to “Installation, Printer
Drivers” sections of this document. You must complete these
steps for your printer to operate properly.
If you have purchased an option package for your printer,
refer to the documentation you received with that option for
installation instructions.
Installation Location
• Place your printer on a firm, solid surface.
• Allow enough space on each side of the machine to easily
access the platen knob and the various paper feed paths.
• Make sure a power outlet is available nearby.
