If anyone has had seen the same or similar issue as mine, I'd appreciate your advice about the next best steps to take.
After several months without printing, I made one print with my Epson 2880, noticed that the Light Vivid Magenta was low (the light was on, the print driver also warned me) so I changed the cartridge. Now new prints appear too pink, especially in "golden" colors: very light yellows, darker gold-like colors, light tans. If it affects other colors (blues, greens, neutrals, saturated reds) it's too subtle a color cast there to be noticeable. I haven't looked closely at what it does to skin tones.
I'm printing on Harman FB Al paper using Harman's ICC profile. I've been using this paper for the last couple years, and since I started using it, I've been happy with the printed results and happy with my ability to soft-proof using a calibrated display. I am going to try making my own profile for the printer, however since the start of the problem coincided with an ink cartridge change I'm a little concerned that there may be something wrong with the printer or ink cartridge.
Yes—I have the correct magenta ink cartridge installed in the right place slot. I did not get the magentas mixed up when changing the cart. I realized today this might be the problem, but I double checked (with a colleague looking over my shoulder just in I've lost my mind), and this is not the issue (if it's even possible).
I have done one automatic nozzle cleaning. Does it make sense to do it again? How many times?
Is this what a faulty ink cartridge does? Has anyone else had problem like this that they were able to solve by just changing the ink cartridge again?
I'm pretty sure this is not a software configuration problem. I've double checked my settings (correct profile, no double profiling), and I've printed from two different computers (a mac and a windows box), with the same pink color cast.
