About the LabelWriter Printer
Congratulations on purchasing a DYMO LabelWriter label printer. Your LabelWriter printer will
give you years of reliable label printing. We encourage you to take a few minutes to review how to
use and care for your printer.
Printer Features
Your LabelWriter printer is a direct thermal printer and does not use ink or toner. Instead, the
printer uses heat from a thermal print head to print on specially treated, heat-sensitive labels. Labels
are the only supplies you will ever need to buy.
Become familiar with the major components of the printer.

The form-feed button on the front of the printer advances a single label. The label eject button is
used to remove labels from the printer when changing rolls.
The status light visually shows the current state of the printer:
•Solid blue - power is on and the printer is ready.
•Flashing blue - labels are not loaded properly or the label roll is empty.
•Dimmed blue - printer is in power saving mode.
System Requirements
The LabelWriter printer requires a USB 1.1 or USB 2.0 connection and one of the following:
•Windows®XP 32-bit
•Windows Vista®32 or 64-bit
•Mac OS®v10.4 or later
Printing Labels
Your LabelWriter printer was shipped with DYMO Label v.8 software to make designing and
printing labels easy. You can also print labels directly from the desktop with QuickPrint, and from
Microsoft Office, ACT!, and QuickBooks with DYMO Label Add-ins that are installed when you
install DYMO Label v.8 software. See the DYMO Label v.8 online Help or Software User Guide
for more information on using these features.

About Labels
DYMO LabelWriter printers use advanced thermal printing technology to print on specially
treated, heat-sensitive labels. This means you will never have to replace toner, ink cartridges, or a
ribbon to print labels.
Note DYMO’s warranty does not cover malfunction or damage that may be caused by the use of
labels other than DYMO-branded labels. Because DYMO LabelWriter printers use thermal printing
technology, you must use specially designed and manufactured labels. The thermal coatings used
on labels other than DYMO-branded labels may not be compatible, and may provide unsatisfactory
printing or cause the printer to malfunction.
How long your labels will last depends on how the labels are used. Thermal paper labels, such as
those printed by the LabelWriter printer, are susceptible to fading in two ways:
•Exposure to direct sunlight, to fluorescent light for an extended period of time, or to extreme
heat will cause fading.
•Contact with plasticizers (for example, labels placed on plastic ring binders) will cause fading.
In the original packaging, the shelf life for LabelWriter labels is 18 months. When labels are used
for short-term applications (envelopes, packages, and so on), fading is not a problem. When labels
are used to label files in a file cabinet, fading is very gradual over many years. Labels applied to the
edge of a notebook that is then placed on a shelf in the sun will show signs of fading within a few
months.
To prolong label life when labels are not in use, store the labels in a cool, dry place and in the black
bag in which they were originally packaged.
Loading Labels
Each label roll comes in a black plastic bag. Make sure to store the label roll in this bag when the
labels are not being used.
The LabelWriter Twin Turbo printer holds two label rolls, so you can print two types of labels
without having to change the label roll. For example, load address labels on one side and DYMO
Stamps postage labels on the other side.
Important!
In order for the labels to feed properly during printing, pay attention to the following when loading
labels on the spool and into the printer:
•The label spool guide must be pushed flush against the label roll, with no gap. See Figure 2.
•The labels must be loaded with the left edge of the label inserted against the left edge of the
label feed slot. See Figure 4.

About Labels
4
Figures 3 and 4 in this section show loading labels in a LabelWriter 450 printer. However, the
instructions apply to loading labels in any LabelWriter printer model.
To load a label roll
1With the printer plugged in, press the form-feed button to
eject the labels that protected the printer during shipment.
2Open the top cover and remove any packing material inside
the label compartment.
3Remove the label spool from inside the cover and separate
the spool guide from the spindle.
4Hold the spool spindle in your left hand and place the label roll
on the spindle so that the labels feed from underneath and the
left edge of the label roll is firmly against the side of the spool.
See Figure 1.
5Slide the spool guide onto the right side of the spool and press
the guide tightly against the side of the label roll, leaving no
gap between the roll and the spool. See Figure 2.
Note To ensure proper feeding of labels during printing, the
label roll must fit snugly against both sides of the label spool,
with no gaps.
6Insert the label spool into the slot in the printer cover with the
labels extending from underneath the roll. See Figure 3.
7Align the left edge of the label with the left edge of the label
feed slot and insert the label into the slot. See Figure 4.
The printer automatically feeds the labels, stopping at the
beginning of the first label.
If the printer does not feed the labels, make sure the first
label is fully inserted and then press the form-feed button.
If the first label on the roll is not a full label, press the
form-feed button to eject the partial label.
Note Regardless of the label width, the left edge of the
label must be aligned with the left edge of the label feed
slot for the labels to feed properly.
8(450, 450 Turbo, and Twin Turbo Only) Slide the label
guide to the left until the label guide aligns with the right
edge of the label. See Figure 4.
Make sure that the label guide does not pinch the label.
9(Twin Turbo Only) Repeat steps 3-8 to load a second roll of labels.
10 Carefully lower the top cover.

Ordering Labels
DYMO offers a full range of labels for the LabelWriter printers, including labels suited for
addressing envelopes, shipping packages, naming file folders, labeling all sorts of media, printing
name badges, and much more. A complete listing can be found in the label catalog that was
supplied with this printer and at the DYMO Web site: www.dymo.com.
Caution DYMO’s warranty does not cover malfunction or damage that may be caused by the use
of labels other than DYMO-branded labels. Because DYMO LabelWriter printers use thermal
printing technology, you must use specially designed and manufactured labels. The thermal
coatings used on labels other than DYMO-branded labels may not be compatible and may provide
unsatisfactory printing or cause the printer to malfunction.
Custom Labels
DYMO also offers several ways to customize your LabelWriter labels. You can order labels
preprinted with text or graphics in any color. For example, shipping labels can be preprinted with
your return address and logo to match your corporate letterhead. Labels are also available in custom
sizes and with special adhesives.
You can obtain details on our custom label program by calling the Custom Label Sales department
at 1-800-426-7827 or send an email to cust[email protected].

Chapter 3
Caring for Your Printer
The LabelWriter printer is designed to give you long and trouble-free service, while requiring very
little maintenance. You will get the best possible performance from your LabelWriter printer if you
follow the setup instructions that appear in the Quick Start Guide and the procedures described in
this section.
You can easily clean your LabelWriter printer using the following items:
•Lint-free cloth.
•Isopropyl alcohol, diluted dishwashing detergent, or diluted glass cleaner.
Caution If you use glass cleaner, make sure it does not contain ammonia.
•Small, soft brush, such as a tooth brush or child’s paint brush.
•LabelWriter cleaning card.
One cleaning card (part number 60622) is included in your printer package. To purchase
additional cleaning cards, visit www.dymo.com or call [phone].
To keep your LabelWriter printer working properly, you should clean it from time to time. Dusting
the outside of the printer occasionally will help keep foreign matter from getting inside the printer.
However, it is still a good idea to periodically perform some basic interior maintenance, such as
cleaning the label path with the cleaning card.
To clean the exterior and interior of your printer
1Disconnect the power cord.
2Use the lint-free cloth to wipe the exterior of the printer.
3Remove dirt and smudges with one of the cleaning solutions mentioned above.
4Open the top cover.
5Use a small, soft brush or cotton swab to whisk away paper dust and other stray particles from
the inside of the printer.
6Remove the roll of labels and clean under the roll.
7If you have a LabelWriter cleaning card, follow the instructions printed on cleaning
card packaging.
8Reconnect the power cord.
9Reload the roll of labels and carefully close the top cover.

Getting Help
Your LabelWriter printer should offer years of trouble-free printing with very little maintenance.
However, in the event that you encounter a problem, this chapter offers suggestions for resolving
problems that can occur when using the printer. If you are unable to solve a problem, this chapter
also describes how to contact DYMO Technical Support.
Troubleshooting
This section provides information on how to detect and correct problems you might encounter
while using your LabelWriter printer.
Status Light
The status light visually shows the current state of the printer:
•Solid blue - power is on and the printer is ready.
•Flashing blue - labels are not loaded properly or the label roll is empty.
•Dimmed blue - printer is in power saving mode.
Performing a Printer Self-Test
If you experience problems with broken characters or other print quality issues, perform a printer
self-test. The self-test verifies that all elements of the print head and printing mechanism are in
working condition.
To perform a self-test
1With a roll of labels in the printer, press and hold the form-feed button on the front of the
printer for five to ten seconds.
The printer begins printing vertical lines along the width of the printer. The test pattern
automatically changes every 3/4 inch (19 mm).
2Once the self-test begins, release the form-feed button.
3To stop the self-test, press and release the form-feed button.
Clearing Label Jams
To clear labels that have become jammed in the printer
1Tear off any labels that have already fed
through the printer.
2Press the platen release lever forward
and pull the jammed label out of the
platen mechanism.
Press platen
release forward

Correcting Poor Print Quality
Poor print quality is most frequently caused by one of the following:
•An old roll of labels
•Labels made by a manufacturer other than DYMO
•Labels where the thermal coating has been compromised
•A dirty print head
First, make sure you are using DYMO-branded labels. Do not use third-party labels because the
thermal coating on other labels has a different sensitivity than DYMO-branded labels. Also, the
perforated holes between the labels made by other manufacturers are frequently not detectable by
LabelWriter printers.
If the print quality becomes faint, small dots of white appear scattered through the printed
characters, or light and dark patches of printing appear, you are probably using a faulty roll of
labels. Try using a different roll from a fresh box. If the second roll prints correctly, the problem is
with the first roll of labels.
Another possibility is that the LabelWriter print head needs cleaning. Every LabelWriter printer
comes with a cleaning card. See "Caring for Your Printer" on page 7 for information about the
LabelWriter cleaning card.
Labels Do Not Feed Correctly
If your labels do not feed correctly, check the following:
•Make sure your labels are loaded properly and that the left edge of the label is aligned with the
left edge of the label feed slot. See "Loading Labels" on page 3.
•Make sure you are using DYMO-branded labels. The perforated holes between the labels made
by other manufacturers are frequently not detectable by DYMO printers. When the
perforations are not detected, the labels will not feed correctly. Using third-party labels may
also void your warranty.
Printer Does Not Print or Stops Printing
If your printer does not print or stops printing while in use, follow the steps below to track down the
problem.
1Make sure the printer is still getting power and that the power cable has not been disconnected.
If the status light on the front of the printer is not lit, check to make sure the power cable is
plugged in, and that your power strip is working.
To make sure the problem is not with the outlet or power strip, try plugging something else into
the wall outlet and power strip.
2Confirm that the printer is feeding labels properly by pushing the form feed button while the
printer is on.
If the labels are jammed, the status light will blink. Refer to "Clearing Label Jams" on page 9.
3Make sure that your USB cable has not come loose from the back of your printer or from
your computer.
Refer to the installation instructions in the Quick Start Guide to make sure the cable is
connected properly.

a. From the Start menu, choose Printers and Faxes.
b. Right-click the LabelWriter printer icon, and then choose Properties.
c. From the Properties dialog box, click Printing Preferences.
d. From the Preferences dialog box, click Advanced.
The Advanced dialog box appears.
