System and method for reliability testing and troubleshooting inkjet printers
First Claim
1. A system for reliability testing an inkjet printing system comprising:
- a testing interface;
a print head coupled to the testing interface;
printer control electronics coupled to the testing interface and coupled to the print head via the testing interface, the printer control electronics adapted to transmit a firing voltage signal through the testing interface to the print head; and
a measurement apparatus coupled to the testing interface;
wherein the testing interface includes an input path for receiving the firing voltage signal from the printer control electronics, the input path splitting into a first path coupled to the print head and a second path coupled to the measurement apparatus.
