UV-Cure Printers Maintaining Jetting & Evaluating Jetting Performance 1
Introduction ColorSpan Legacy UV-cure printers use sixteen piezoelectric printheads, each with 96 jets. Piezo printheads, when properly maintained, are reliable and long-lived. In addition to the inherent robustness of the technology, the printer has built-in software features that can identify jets that, for whatever reason, are not firing as expected, and “map out” or replace the non-working jets with substituted, good jets.
When Jets can not be Replaced in Production Mode The printer’s warranty clearly defines the criteria under which a printhead will be replaced at the manufacturer’s expense. Printheads that develop missing jets through any other conditions, including but not limited to headstrikes, exposure to poor environmental conditions, or neglected routine maintenance, are not subject to warranty replacements.
