G'day ya'll
So, I have an Epson xp-100. All printing has been great, but all of a sudden it's only printing Black out of the 4 colours. All cartridges are registering as full on the computer, have cleaned all the nozzles & all are letting solution flow through.
Before nozzle clean, it was only printing small random black lines, cleaned & put cartridges back in, now it's only printing the black parts correctly (I wrote four words in black, yellow, blue & red as a test before printing a full picture & only the word in black is printing)
Can anyone help as to what the problem maybe. I havent been printing with sub ink long.

Check to see if somehow the print separations has been clicked on in the colors menu. If it has it will only print 1 color at a time.

Had a quick look & no that hasnt been selected. I'm also getting small, fine, random yellow lines aswell as the complete black section. I'm pretty much stumped atm

Does it do a Nozzle Check correctly? Sublimation ink can clog the small filters within the cartridges themselves. You may have to get new cartridges if that's the case.
