I’ve received my IJM ink kit for the 3880 (HD PK) and have installed all inks except matte and photo black (printer set to use PK) - for these two I have enough Epson ink.
My first nozzle check looks good, except for yellow; there may be no clogs with yellow, but I can’t evaluate because the yellow nozzle check is so faint. I can see a yellow area of the correct size, but individual yellow lines are so light that I can’t see if all are present.
My next step is to get a replacement maintenance cartridge and then try some small prints.
What might be happening here and what should I try?
PS - Need to clarify: the yellow appears light, not faint. In other words, it appears like a yellow highlighter as opposed to the more mustard Epson color.
