Getting Started
This section describes how to set up your printer for the first time and use
the most common operating procedures for loading media in tear-off mode.
Modes of Printing
You can operate this printer in different modes:
�
Standard tear-off mode allows you to tear off each label (or a strip of
labels) after it is printed.
�
In optional peel-off mode, the backing material is peeled away from the
label as it is printed. After this label is removed, the next one is printed.
�
In optional liner-free mode, labels have no backing. This option is only
available with a special platen.
�
In optional cutter mode, an attached unit cuts through the media.
The printer typically uses roll media, but you can use fan-fold or other
continuous media as well.
For procedures to use optional modes and features, refer to the Operation
and Options section.

Hooking Up the Printer and Computer
Your printer will have one of two combinations of interfaces:
�
Universal Serial Bus (USB), parallel and serial
�
USB, ethernet, and serial
Each specific interface option—USB, parallel, ethernet, serial—is discussed
individually.
You must supply the required interface cable for your application.
CAUTIONS:Keep the power switch in the OFF position when
attaching the interface cable.
The power supply barrel connector must be inserted
into the power supply receptacle on the back of the
printer before connecting or disconnecting the communications cables.
This printer complies with FCC “Rules and Regulations,” Part 15, for Class B Equipment, using fully
shielded six-foot data cables. Use of longer cables or
unshielded cables may increase radiated emissions
above the Class B limits.
Interface Cable Requirements
Data cables must be of fully shielded construction and fitted with metal or
metalized connector shells. Shielded cables and connectors are required to
prevent radiation and reception of electrical noise.
To minimize electrical noise pickup in the cable:
Keep data cables as short as possible (6’ [1.83 m] recommended).
Do not tightly bundle the data cables with power cords.
Do not tie the data cables to power wire conduits.

USB Interface Requirements
Universal Serial Bus (version 1.1) provides a high-speed interface that is
compatible with your existing PC hardware. USB’s “plug and play” design
makes installation easy. Multiple printers can share a single USB port/hub.
Parallel Interface Requirements
The required cable (IEEE 1284-compliant is recommended) must have a
standard 36-pin parallel connector on one end, which is plugged into the
parallel port located on the back of the printer. The other end of the parallel
interface cable connects to the printer connector at the host computer.
For pinout information, refer to page 42.
Ethernet Interface Requirements
Ethernet provides a powerful networking capability that can be of use in a
variety of internet/intranet printing solutions. After you load media and
close the top cover, you can press the test button next to the connector on
the rear of the printer to get an ethernet configuration label.
Serial Interface Requirements
The required cable must have a nine-pin “D” type (DB-9P) male connector
on one end, which is plugged into the mating (DB-9S) serial port located on
the back of the printer. The other end of this signal interface cable connects
to a serial port at the host computer. Depending on the specific interface
requirements, this will most likely be a straight-through cable.

Operation & Options
This section helps you get the most from your printer.
You must use programming to control many of the printer’s functions. A
few examples:
�
TheQcommand (set form length) controls label length.
�
TheOcommand (hardware options) has a parameter "D" that changes
the printing mode to direct thermal.
For detailed information about creating labels using page description
programming language, refer to the programming guide.
To improve print quality, changing both print speed and density may be
required to achieve the desired results. Your application’s printer driver
provides control of the speed and heat (density).
Thermal Printing
The print head becomes hot while printing. To protect from damaging the
print head and risk of personal injury, avoid touching the print head. Use
only the cleaning pen to perform maintenance.
The discharge of electrostatic energy that accumulates on the surface of the
human body or other surfaces can damage or destroy the print head or
electronic components used in this device. You must observe static-safe
procedures when working with the print head or the electronic components
under the top cover.
You must use the correct media for the type of printing you require. You
must use direct thermal media.

Using the Cutter Option
Printers that have a bezel with a motorized blade can dispense one or more
forms that are then automatically cut from the media supply. This option
cuts through continuous paper from rolls and liner between labels. Keep
the cutter dry. Never use any solutions or solvents to clean the blade.
Use the
f
command to set the cut position and theCcommand to cut
immediately outside a form.
If the blade cuts through labels, adhesive
can jam the cutter.
1. Turn OFF (O) printer power and
unplug the power and interface cables
before clearing the cutter.
2. After removing debris, plug in the
power and interface cables, turn on
the printer, then test for normal
operation.

Maintenance
Cleaning
When you clean the printer, use one or more of the following supplies that
best suits your needs:
DESCRIPTION
Cleaning pens (12)
Cleaning swabs (25)
Cleaning cards, 4-in wide (25)
Save-a-Print Head film, 4-in wide (3)
The cleaning process takes just a couple of minutes using the steps outlined
below.
Printer Part Method Interval
Print head
Let the print head to cool for one minute, then use a new
cleaning pen to swab the print elements (the thin gray
line on the print head) from end to end. NOTE: You do
not have to turn off the printer to do this.
If print quality remains poor after cleaning, try the
Save-a-Print Head cleaning film to remove buildup
without damaging the print head. Call your authorized
reseller for more information.
As
necessary
or after
every five
rolls of
media
Platen roller
Manually rotate the platen roller. Clean it thoroughly
with 70% isopropyl alcohol and a cleaning swab,
cleaning card, or lint-free cloth.
Peel bar
Clean it thoroughly with 70% isopropyl alcohol and a
cotton swab.
As needed
Tear bar
Exterior Water-dampened cloth
Interior Brush or air blow
Cutter Use tweezers to remove scraps

PAGE 29 OF 47
0808 IH-970
Adhesives and coatings of media can over time transfer onto the printer
components along the media path including the platen and print head.
This build-up can accumulate dust and debris. Failure to clean the print
head, media path and platen roller could result in inadvertent loss of labels,
label jams and possible damage to the printer.
Print Head Considerations
Always use a new cleaning pen on the print head (an old pen carries
contaminants from its previous uses that may damage the print head).
Media Path Considerations
Use a cleaning swab or pen to remove debris, dust or crust that has built-up
on the holders, guides and media path surfaces.
1. Use the alcohol in the cleaning swab or pen to soak the debris so that it
breaks up.
2. Wipe the area with the cleaning swab or pen to remove the debris.
3. Discard the cleaning swab or pen after use.
Cleaning Card Considerations
Use a cleaning card to remove debris that has built-up on the platen. Avoid
scrubbing or vigorously rubbing the platen; otherwise, the surface could be
damaged.
1. Open the printer and remove labels.
2. Place the cleaning card into the label path so that it is under the guides
and it extends between the print head and platen roller.
3. Close and latch the printer.
4. With the power switch on, press the feed switch to move the cleaning
card through the printer.
5. Discard the card after use.

Platen Considerations
The standard platen (drive roller) normally does not require cleaning. Paper
and liner dust can accumulate without effecting print operations.
Contaminates on the platen roller can damage the print head or cause the
media to slip when printing. Adhesive, dirt, general dust, oils and other
contaminates should be cleaned immediately off the platen.
However, the non-stick platen roller on linerless media printers requires
frequent cleaning to keep adhesive buildup from occurring and transferring
to the print head and the media path. Keep a new platen available as a spare
and install it whenever the printer has significantly poorer performance,
print quality or media handling. If sticking or jamming continues even after
cleaning, you must replace the platen.
The platen can be cleaned with a fiber-free swab (such as a Texpad swab)
or a lint free, clean, damp cloth very lightly moistened with medical grade
alcohol (70% pure or better).
1. Open the media door and remove the media.
2. Clean the platen surface with the alcohol moistened swab. Rotate the
platen while swabbing. Repeat this process two to three times with a
new swab to remove residual contaminates. Adhesives and oils, for
example, may be thinned by the initial cleaning but not completely
removed.
3. Discard the cleaning swab or pen after use.
Allow the printer to dry for one minute before loading labels.
Lubrication
No lubricating agents of any kind should be used on this printer! Some
commercially available lubricants, if used, will damage the finish and the
mechanical parts inside the printer.
