Hey all! K question for you. I have an Epson f6070 that starts printing with horizontal bands which get worse over the course of a print job. I can start with perfectly clean nozzle check and the first few images often look good before the banding kicks in. Especially on the darker colors, it seems to be over-depositing ink on one side of the pass and not enough on the other side. Eventually, consistent white streaks start forming that are painfully obvious. A nozzle check after the print job shows gaps across all of the colors, all at about the middle of the print head.
I've tried pretty much everything at this point. I'm using high quality and genuine epson inks that are well within their expiry dates (although they've been in their cartridges for about 5 months now). My printer room is humidified, I've done multiple cleanings, even a manual head cleaning. I'm using Wasatch SoftRip and it's printing uni-directional, highest quality, 4 passes (basically as slow and high quality as it gets). I've been trying to print at least once a week just to keep the thing well-lubed. This printer is old and well used so there's a decent chance that the head is failing and if that sounds like the case, definitely let me know. It may just be time to buy a new one. Any thoughts or recommendations would be sweet, thanks!
