Well, I guess I will throw my hat into the ring also. I'm having the same issue as everyone else here with the caveat that we are about 6 months out of warranty. My cyan channels are all firing, but they are badly deflected. (I can't figure out how to add a photo, otherwise, I would have.) I've followed the maintenance schedule to the letter, so I'm baffled by why this is happening. All of our other channels are perfect. Cyan is the only problem child we have at the moment. Last night it was working fine. This morning it wasn't.
I've tried everything I can think of today. I've done a tube wash, run multiple heavy cleans on the Magenta/Cyan channel, cleaned around the capping station and suction cap, cleaned around the head, redid the alignment, shaken the cyan cartridge, stood on my head, and still no luck.
The answer can't always be replacing the head. This is the most cost- prohibitive repair there is, and it's almost always the recommended solution to any problem. We're a small shop, and I'd really prefer to avoid sinking another $2 grand + into this machine, especially with all the posts here telling me the problem has recurred only a few days after the replacement.
Isn't there a way to actually clean the head (not just around the head) without risking significant damage? If there's some lint stuck under there, and the machine isn't able to clear it out, there has to be a way to clean it manually right? I'd be grateful for any and all suggestions.
