Against most expert opinion and advice, your's included, I bought the 9900 from the CCAD, Columbus College of Art and Design(?), as well as a 4900 they had because who can pass up a great deal???? Apparently not me.
I didn't do any nozzle checks for fear the ink, old but there, would potentially exacerbate any existing clogs.
Should I do all of the soaking, cleaning, and parts replacing before I do a nozzle check?
Going in I know the 9900 will be for piezo with either the existing head if it will clean or a new one if not, and I'll use your cone color ink in the 4900.
I'll look through your site for advice on cleaning, maintenance, and parts replacement for both printers before I make a list of needed parts. Do you have a favorite Epson parts vendor?
What's life without a challenge or two? Don't answer that.
Thank you, Joe
