Evaluating Jetting Performace Steps to Jet Recovery 1
Overview The ColorSpan Legacy solvent ink printers (72s, 72sr, 72 & 98si, all commonly called “Gator”) each 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 Gator 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.
To ascertain that any and all jets that have been mapped out by the software are being replaced, print the JetOut Lines pattern found under the Maintenance Menu. Jets that are mapped out are marked with a black tick. If a replacement jet exists for the mapped-out jet, the black tick will be filled in by another jet, indicating that the jet is replaced. See the illustration below: This Jet-Out Lines example shows a jet that has been mapped-out and has a replacement.
