Epson XP-15000: how to mix dye ink with clear ink base to obtain red and grey using CMYK

[Ink stained Fingers]

My question was about the 105 ink, because it is pigment ink, that would give a better black on Matte Papers.

No, you cannot make such general statements that a pigment ink always delivers a better black, it's always a matter of the ink and paper - the coating - combination how that performs together.
The ET-7750 with the 105 black was designed as a multi-purpose printer with good performance - a pigment black on normal paper delivers a much sharper edge definition on black letters since the pigments are too big to migrate into the fibrous surface , you have a stronger dot gain with dye inks for this reason. You'll find reports here in some forum stating that a dye black delivers the best black.........

You can technically swap ink cartdidges loaded with dye or pigment inks, tha's what I actually do on a WF-2010W for test purposes, but this requires you to clean/flush the black ink channel quite intensively. I did it as well on a printer like the L800/L1800, but I succeeded to do it only 2 or 3 times, and clogs got persistent . The L800/1800/805 print with a smaller nozzle size - droplet size of 1.5 vs. 3.5 pl of the WF-2010W which may cause this. Swapping inks this way is not a reliable practice for regular printing.

Ok now i understand your point,

intensive clean and flush of the channel without considering the clog possibility between the cartridge change let me decide to use only the 106 dye black, i was supposing wrong

thanks for your findings and hints
