Status Light

The status light visually shows the current state of the printer:

Status Light


Solid Blue

Power is on and printer is ready.

Dimmed Blue

Printer is in power saving mode.

Flashing Blue

Labels are not loaded properly or the label roll is empty.

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.

1. With 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).

2. Once the self-test begins, release the form-feed button

3. To stop the self-test, press and release the form-feed button again.

Clearing Printer Jams

1. Open the top cover of the printer.

2. Locate the eject button on the right-hand side of the printer. The button has a white arrow on top of it.

3. Press the button to eject the labels and remove them from the feed.

4. Remove the front black cover by placing your fingers beneath it and gently lifting up and pulling it towards you.

5. Locate the label guide (grey tab) on the right-hand side. Pull it up and towards you to expose the label feed.

Check for debris or labels jammed in this area and remove, if necessary.

6. Locate the black spring loaded lever on the left-hand side. Pull the lever towards you while tilting the printer back 30 degrees so that you can see under the printer.

Look for labels jammed in the roller. Clear all jams. You may need to use alcohol to clean the residue left by the sticker on the roller.

7. Place the front cover (black) back on by aligning the two hinges on top. Carefully apply pressure to the bottom of the cover until you hear the two tabs on the bottom click into place.

8. Replace the labels by feeding them into the printer with the labels facing down and the hole-punch on the left.

9. Close the top cover of the printer.

10. Press the blue feed button on the front of the printer to ensure that the labels are properly loaded and are feeding.

11. Check the print queue and clear it if there are pending jobs.

12. Test print a badge in Raptor.

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 Raptor

  • Labels where the thermal coating has been compromised

  • A dirty print head

First, make sure you are using Raptor-branded labels. Do not use third-party labels because the thermal coating on other labels has a different sensitivity than Raptor-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 17 for information about the LabelWriter cleaning card.

Adjusting Label Brightness

If the visitor photos are printing too dark or too light, you can adjust the brightness setting. Perform the following steps to adjust the brightness setting.

1. On the Windows desktop, click Start > All Programs > Vsoft > Printer Manager.


2. On the Printer Manager dialog, move the Brightness and Contrast slider bars to the desired level. Raptor recommends a brightness setting of 55+ and a contrast setting of 0.


3. Click Test Print to print a badge and view the results of the changes to the brightness and contrast settings.

4. When satisfied with the settings, click Apply Changes.

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.

  • Make sure you are using Raptor-branded labels. The perforated holes between the labels made by other manufacturers are frequently not detectable by Raptor printers. When the perforations are not detected, the labels will not feed correctly. Using third-party labels may also void your warranty.

Replacing Labels in Printer

It is recommended that you replace the labels in the LabelWriter printer before the last one is used so that there are no pending print jobs in your print queue after you have replaced the labels.

In order for the labels to properly feed during printing, ensure that you perform the following tasks when loading the labels onto the spool and into the printer:

  • Cut the first three labels of the new roll.

  • Ensure the label spool guide is pushed flush against the label roll, with no gap.

  • Ensure the labels are loaded with the left edge of the label inserted against the left edge of the label feed slot.

To load a label roll:


  1. With the printer plugged in, press the form-feed button to eject the labels that protected the printer during shipment.

  2. Open the top cover and remove any packing material inside the label compartment.

  3. Remove the label spool from inside the cover and separate the spool guide from the spindle.

  4. Hold 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.

  5. Slide 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.)

  6. Insert the label spool into the slot in the printer cover with the labels extending from underneath the roll. See Figure 3.

  7. Align 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. 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 la

  8. For the LabelWriter 330, 400, 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. (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.)
  9. For the LabelWriter 450 Twin Turbo only, repeat steps 3-8 to load a second roll of labels.
  10. Carefully lower the top cover.

Printer Does Not Print or Stops Printing

If your printer will not print visitor badges or stops printing while in use, perform the following steps to resolve the issue.

1. Make sure the printer is still getting power and that the power cable has not been disconnected.
  1. 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.

  2. To make sure the problem is not with the outlet or power strip, try plugging something else into the wall outlet and power strip.

2. Verify that there is a steady blue light on the front of the printer. If there is not a steady blue light, verify the printer is properly connected:
  1. On the bottom back side of the printer, ensure that both the power cord and the printer cable fit snugly in place.

  2. Verify that the other end of the L-shaped power cord is plugged into a power outlet.

  3. Verify that the printer cable is connected securely to your computer (it must be connected directly to the computer, not a hub or docking station).

3. Confirm that the printer is feeding labels properly by pushing the blue form feed button on the front of the printer to advance a badge. If labels are advancing, continue to the Print Test in Step 5. If the labels are jammed, the status light will blink.

4. If the labels are jammed, remove them. See Clearing Printer Jam document before continuing.

5. Print a test badge from Printer properties:

  1. Right-click the DYMO Labelwriter 450 printer and select Printer properties.

  2. On the General tab, click Print Test Page. If successful, a small Windows icon or the word Win will print on a visitor badge.

  3. Click OK to exit the dialog box.

If the test badge does not print:

      a. Unplug the L-shaped power cord from the printer, wait a full 10-20 seconds (blue light is off), and then reconnect the power cord.
      b.Click Print Test Page to print a test badge.
      c. Click OK to exit the dialog box.

6. Verify there are no pending print jobs in the print queue that contain errors:
  1. Click Start> Devices and Printers.

  2. Double-click the DYMO Labelwriter 450 printer and verify there are no pending print jobs in the print queue that contain errors.

  3. If there are pending jobs, click Printer > Cancel All Documents, and then click OK. 

7. It might also be necessary to restart the Print Spooler service.
  1. Click Start and type Services in the search box.

  2. Select View local services.

  3. Scroll to Print Spooler and click Restart.

8. If test print is still unsuccessful, verify that the LabelWriter printer driver is installed correctly.

The LabelWriter printer driver takes print data from your software and directs it to the LabelWriter printer. The driver is automatically installed when you install the software that comes with your printer. However, the driver may have been changed or deleted by mistake.

  1. From the Start menu, choose Printers and Faxes.

  2. Right-click the LabelWriter printer icon, and then choose Properties.

  3. From the Properties dialog box, click Printing Preferences.

  4. From the Preferences dialog box, click Advanced.

              If no errors are displayed the Advanced dialog box, the printer driver is installed correctly.

9. Log into Raptor and print a visitor badge.

Cleaning 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 perform the procedures described in this document.

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 is included in your printer package. To purchase additional cleaning cards, visit, and choose Maintenance Kits and Door Signs > Maintenance Packet.

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 of your printer and the label roll compartment

  1. Disconnect the power cord.

  2. Use the lint-free cloth to wipe the exterior of the printer.

  3. Remove dirt and smudges with one of the cleaning solutions mentioned above.

  4. Open the top cover.

  5. Use a small, soft brush or cotton swab to whisk away paper dust and other stray particles from the inside of the printer.

  6. Remove the roll of labels and clean under the roll.

  7. If you have a LabelWriter cleaning card, follow the instructions printed on cleaning card packaging.

  8. Reconnect the power cord.

  9. Reload the roll of labels and carefully close the top cover.
