Hi does anyone know were to buy a new L1800 printhead

Quick Google search shows OEM around £240. You can source them from China for much less but need a good supplier. Alibaba/AliExpress etc.

If you are using it for Sublimation then you could grab a third party one off Amazon for less than £30.00 The viscosity of sublimation ink is quite thin so the head should work exactly the same as a OEM.

However if you are using it for something other than sublimation ink (DTF for example) then firstly you are better off getting an OEM as they are built better and can "handle" thicker ink.

However, getting an original head might be an issue as you have to be an authorised Epson engineer to purchase. I think that will change soon though, many DTF machines use Epson heads which many consider to be a part that needs replacing every now and then, "proper" DTF machines are built so that the head can be replaced in minutes. With so many of them using Epson heads I do not think it will be long before you will be able to purchase the heads anywhere.

BCH Technologies Known for printer parts and ink solutions, they may carry the printhead you need or suggest alternatives.
