The print head is a delicate and expensive part of the bar code printer and is also a fragile and vulnerable device. It is a depletion product like a car, and it will eventually be damaged. Only the constant attention to maintenance can extend the life of the print head.

In order to play a better role, one print head needs to be cleaned every time a roll of ribbon or a roll of thermal paper is used up. CAUTION When cleaning the print head, remove hard objects such as rings to prevent scratching the print head, and be careful not to damage the print head with a grounded metal strip or an object with static electricity.

Causes of premature printhead damage: Scratches - The long-term movement of the label ribbon through the printhead wears the protective layer of the ceramic coating, exposing the printhead needle (point) to damage. Always clean the printhead and use it. High quality, smooth and back-coated thermal transfer ribbon to reduce friction. Minimize print head pressure and print temperature. Make sure that the ribbon width is wider than the label to prevent the exposed printhead from being scratched by the label. After the print head is contaminated by the thermal transfer ribbon, settings for high temperature, high pressure, and high line height will be required. The accumulation of contaminants on the printhead needles causes heat transfer obstacles that affect the print image quality. Gradually increasing contamination will degrade print quality and look matt or damage the print pin.

Use a thermal transfer ribbon that already has a back layer protection (with static and lubrication). Senmao Technology recommends that you always perform print head maintenance. Using our protective print head film can quickly and easily remove print head debris.
