Dymo LabelWriter 450 Twin Turbo - Until recently
See if it still happens using a fresh label roll. From the Dymo 450 User Guide the common causes of poor print quality issues.
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 17 for information about the
LabelWriter cleaning card.
