Cleaning Intervals and Procedures

Routine preventive maintenance is a crucial part of normal printer operation. By taking good care of your printer, you can minimize potential problems and achieve/maintain the desired print quality standards.

Over time, the movement of media or ribbon across the printhead wears through the protective ceramic coating, exposing and eventually damaging the print elements (dots). To avoid abrasion:

Clean the printhead frequently.

Minimize printhead pressure and burn temperature (darkness) settings by optimizing the balance between the two.

When using Thermal Transfer mode, ensure that the ribbon is either as wide or wider than the media. This is to avoid exposing printhead elements to the more abrasive label material.

Zebra is not responsible for damage caused by the use of cleaning fluids on this printer.
