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 these combinations of interfaces:  
Parallel  
Universal Serial Bus (USB) and DB-9 serial  
Ethernet and RJ-11 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 com-  
munications cables.  
This printer complies with FCC “Rules and Regula-  
tions,” 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 standard 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 cable is a straight-through type.  
There is an optional serial interface that uses a 6-pin RJ-11 male connector  
on one end, which is plugged into the mating RJ-11 alternative serial port  
located on the back of the printer.  
The other end of the signal interface cable connects to a serial port at the  
host computer. Depending on the specific interface requirements, this will  
most likely be a null modem cable.

command (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.

Replacing Supplies  
If labels run out while printing, leave the printer power on while reloading  
(data loss results if you turn off the printer). After you load a new label  
roll, press the Feed button to restart.  
Always use high quality, approved labels and tags. If adhesive backed  
labels are used that don’t lay flat on the backing liner, the exposed edges  
may stick to the label guides and rollers inside the printer, causing the label  
to peel off from the liner and jam the printer. Approved supplies can be  
ordered from your dealer.

Printing in Peel-Mode  
The optional dispenser allows you  
to print in “peel-mode” where the  
label backing follows a different path and  
the labels are presented one at a time for  
subsequent placement.  
1. Remove several labels from the  
backing material.  
2. Open the top cover.  
3. Open the dispenser door.  
4. Switch on the label-taken sensor.  
5. Insert the backing in front of the peel  
bar and behind the peel roller.  
6. Close the dispenser door.  
7. Close the top cover.  
8. Press the Feed button to advance the  
label.  
During the print job, the printer will peel  
off the backing and present a single label.  
Take the label from the printer so it will  
print the next label.

Printing on Fan-Fold Media  
Printing on fan-fold media requires you to  
set the media hangers in position.  
1. Open the top cover.  
2. With a sample of your media, adjust  
the media hangers to the width of the  
media. The hangers should just touch,  
but not restrict, the edges of the  
media.  
3. Lock the hangers and guides into  
position by sliding the lock forward.  
4. Insert the media through the slot at the  
rear of the printer.  
5. Run the media between the hangers  
and through the guides.  
6. Close the top cover.

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 the  
C
command 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.

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).  
MOVIE  
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.  
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.

Serial (RJ-11) Alternative Connector  
The printer operates as a Data Communication Equipment (DCE) and those  
printers with ethernet connectors also have an alternative serial RJ-11  
interface used to connect to a Data Terminal Equipment (DTE) such as a  
computer or terminal with a default configuration of 9600 baud, 8 bit data,  
1 stop bit and No parity.  
Note that looking into the printer's connector with the key notch pointing  
down, pins are numbered from left to right.
