Default Re: DX5 Printhead - Regular failure on ONE Colour Channel

You forgot to mention which color is the one failing.

Normally the channel of the most used color will fail first.
If you switch that color to a different channel, the failure occurrence will should also move. If not, then the problem is somewhere else.

Losing all the nozzles at the same time is not normal. My guess is that you have a faulty mainboard and it is somehow burning a particular channel.

There is no programmed failure in the printheads.
"Locked" means that the printhead will work on EPSON printers only.

How many prints are we talking about before the failure?
