factors that contribute to early printhead failure
1. Corrosion. Your printhead’s protective coating can become damaged if substances which contact it are themselves corrosive.
2. Contamination. When thermal labels or other media come in contact with abrasive materials and then pass through the printhead, they can cause contamination.
3. Abrasion. Abrasion is most often caused by friction. In particular, paper dust can collect on the platen toward the outer edges of the media or ribbon and, in turn, abrade the printhead glaze.
4. Residue buildup. Buildup of thermal ribbon or media coating on the printhead can cause overheating and eventual failure.
5. Printhead pressure. Related to abrasion, excessive pressure increases friction on the printhead assembly.
Electrostatic discharge. Characterized by a sudden, unexpected electrical flow between two electrically charged objects, electrostatic discharge can cause significant damage to a printhead’s internal circuitry.
6. Environmental factors. The environment in which your printer operates plays a role in how long that printhead can last over time.
