Dymo: Recommended Cleaning

The LabelWriter printer is designed to give you a 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. 

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. 

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 toothbrush or child’s paintbrush. 
  • LabelWriter cleaning card. To purchase cleaning cards, visit www.dymo.com.

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.

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

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.

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. See "Caring for Your Printer" on page 17 for information about cleaning the label path with a LabelWriter cleaning card.
