Poor Print Quality from Electronic Labelmaker Question I have an electronic labelmaker that is printing poorly. The print on the label is either very light, incomplete, or striped. How can I resolve this?
Answer Proceed with the solutions listed below if you have an electronic labelmaker. If you have a LabelWriter printer that is printing poorly, click here.
Solution 1:
Replace the existing batteries with a new/fresh set of alkaline batteries. The print head requires a significant amount of battery power to ensure proper printing on the label. Light print on the label may be an indication that the batteries need to be replaced.
Solution 2:
Replace the existing tape cassette with a new tape cassette. Light printing may be an indication of bad label stock.
Solution 3:
Using the special brush supplied with your labelmaker (located on the inside cover of the cassette compartment) or a cotton swab with a soft solvent (e.g. rubbing alcohol), carefully clean the transporter roller and print head. Dust, dirt, or glue may accumulate on the rubber transport roller or print head inside the cassette compartment and adversely affect print quality.
