Theory of Operation
Purge System
Proper Printhead operation is dependant on the purge system shown in Figure 1. The purge
pump pushes air into the Printhead to purge any debris or air bubbles that may be obstructing
the Printhead jets.
Waste ink expelled during a purge cycle is removed from the Printhead Faceplate by the Wiper
Blade and collected in the Waste Tray. Following the purge, a cleaning page is printed.
Auto Purge is an automatic cleaning cycle, which is performed when the printer is powered and
the Printhead temperature is below 90 degree C. Manual Purge and Advanced Purge are
cleaning cycles that can be performed from the Control Panel. Advanced Purge focuses on the
selected problematic jet.
Purge Mass is the amount of ink collected in the Waste Tray following the purge.
Purge Efficiency is the success rate of a cleaning cycle, measured as the percentage of times
a single printer performs a cleaning cycle with no missing jets following that cycle. Purge fail
-
ures are only counted for weak or missing jets that can be cleared by cleaning cycle.
