Diagnosing Epson L3250 Printhead: Is Diode Mode Enough?

Hello, and thank you for your helpful content.I have a question regarding printhead diagnostics for the Epson L3250.I'm trying to determine whether the printhead is electrically healthy or if there's an internal short or open circuit.Is it sufficient to use the multimeter in diode mode with inverted polarity to detect electrical faults in the printhead? Specifically, I placed the positive probe on the ground pin and the negative probe on each signal pin.My readings were:• Pin 1 = 0• Pin 2 = 0.647• Pin 3 = 0.573• All remaining pins = 0Does this indicate that the printhead is functioning correctly, or could there still be hidden faults that require testing in both directions or using resistance mode?I would appreciate your expert opinion and guidance. Thank you in advance.

Such electrical measurement won't tell you anything about clogged nozzles.

What is the problem you have with the L3250 ? It is very successful flushing the printhead - wihtout
taking it out , there are plenty Youtube videos showing the process.
