I’ve been wrestling with my 4900 for almost a year. Replacing the pump temporarily solved the problem so I loaded Piezography inks and had about a month of good printing time. The cyan channel began to show signs of clogging and cleaning, using the Epson “technicians” software (service program), didn’t help. I loaded a flush cartridge into the cyan slot about 2 months ago, performed an ink flush until the test showed flush color, shut it off and let it sit for a week. That was a few months ago. In that time I’ve done daily cleans, let it rest a few days and cleaned, and other versions of a cleaning “schedule”. The most recent was a week ago. Prior to leaving for Don Messec’s workshop in Sante Fe I did a level 2 clean and test print. Nothing changed.
Bear in mind that I’ve had Piezoflush in the cyan channel for months. The image below is as good as it gets.
The scan below is of the alignment check sheet that I printed this morning using the service program. My Epson 10000XL scanner isn’t color managed so I had to “push the image around” in photoshop to accentuate the color of the flush so the black channels may seem to have a slight tint to them. They don’t have any tint in the real world.

At this point I’m not sure if I should
a) abandon all hope and wait for Piezography and the Epson P800 series to become compatible.
b) buy another 4900 (not my favorite choice) so I can make use of all of the cartridges that I have for the 4900
c) take up knitting and forget about all this printing stuff (not going to happen…)
Suggestions for ways to fix or a cheap source for a new head my 4900. I’ve had it for a very long time. Something like 5 years. It was problem free for about 3.5 of the 5 years. The problem, in my opinion, started a little over a year ago, with the pump but escalated to the head due to power cleaning too often and a number of other mistakes that can be found in bad internet advice.
