Hello Shirtexplorer,

thank you for your feedback but we disagree with the above statement. Head cables can burn a printhead but its not possible to make the printhead lose nozzles during printing.

Sorry, funny way, the exchange of the printheads and the ink supply has brought nothing. Even your contractors have told me that they can not help under these circumstances. I should scrap the device.
After replacing the cable and testing for 3 years and burning money, the machines now print consistently, even after the tenth T-shirt. I lose no white channel anymore, I can show you a picture of the cable.

I suspect the previous owner of the machine has misplaced too much cleaning fluid, because he had the same problem.

Everything else would mean that all of my printheads or other parts were faulty, I can not believe that Epson would sell something like that.

We had this issue with other colours except for white during hot weather in the past.

Yes, Epson print heads struggle with white ink
NoIt's not the end of the world if maintained properly

Print head can only handle a limited size droplet of ink, generally bad ink is the case. If the white is not shaken enough to get rid of the gunk on the bottom of the cartridge, imagine what that micro mm of gunk can do to your print head.

When we received training on the printer when we first received it 2 years ago, the tip is... Shake the white until you can see the ink run off the bottom and bubbles "popping" when turning the cartridge on it's side.

DO NOT turn upside down fully so the ait filter doesn't get clogged as they could also cause a problem which will mean low pressure for that cartridge.

Well maintained ink and proper cleaning does actually work... this is from experience from 1000s of prints
