It's the L365 driver print to XP-2101 printer on Premium Photo Glossy Quality, I also check the Matte High.
The paper still the 130gsm Inkjet cast coated paper.
I would try on my RC glossy paper later.
I also check the Stylus Pro 4000 glossy paper behavior, it seems like not only full PG black...
Tried T5431 PB on the same 130gsm Inkjet cast coated paper
Printer XP-2101
Driver L365
media type: Premium Glossy Quality
But the Black in only black seems not so black, it lost reflection after dry out.
The measurement also seems like it's not so black as other black with CMY mixed.
Trying to compare each channel ink printed by printer+driver (ICM disabled)
Paper: EPSON OEM SKU:C13S041786 102gsm Photo quality Inkjet paper (Presentation Paper Matte)
Besides L655 still can't decode, other EPSON drivers confirmed each color only utilize one dedicate Ink channel.
But L800...
The windows 10 printer test page only check black & cyan 😁
I miss the one on windows 7 with Color Logo
Tried to print the test page to pdf, but I didn't found the visible blue background.
Just confirmed it would apply the printer preference setting.
(Tried to set to glossy on epson to identify...
Figure out why XP-240 driver Dmax so low on T664 dye inks, the matte paper media on the driver only print black by CMY channel like glossy paper. Also explained why the chromaticity is not like the XP-2101, since it's the same as glossy media.
Maybe this issue? or symptom fix since XP-2100 driver.
True, I can't found any Epson photo black pigment oem ink.
It's also one of the reason I haven't transfer my L800 to other non-oem ink yet.
Oops, admit I have another 6-color printer.:)
I did have some different cheap glossy paper, premium RC/PE glossy photo paper and
some canon OEM SG-201...
The T774 pigment black seems like would smudge by finger on the paper I use.
It's 130gsm , coated, glossy.
I don't have a precise paper name, since it sale as the paper for the prepress proofing on inkjet printer.
It should touch like flyer.
Anyway, I would get the T542/T06G Durabrite Black Ink...
Only L655, XP2101 & TX430W are physical exist printers. (I also have some other Ecotank models, at first I try to fix broken L550 & L655 from coffee shop retired machine. And dig into other color issues etc. It's a long story... Anyway, I have 7 EPSON printers running in my room now:oops:)
Other...
Just found I am wrong about the Claria Home ref 202 cartridge. It's actually pigment black + CMY dye.:eek:
But the driver behavior for chromaticity on XP245 seems like similar to the L365. Except the Dmax, the driver on XP245 limits like L655 & WF2650.
When I try to fill the 4 color pigment oem ink to L655, I notice the profile seems like similar to the original T774pigment +T664 dye. (Matte media type)
But seems different to the 4 dye inks printer, I am wondering if they can works better on 4 dye inks model?
But unfortunatly I can't find...
Based on the Epson Claria Ink blog, seems like only Claria Premium & Photo HD got better longevity.
Only found T212 might be exactly the same as T522
Try to summary the Ecotank Ink tables.

With three individual dye-color ink cartridges...
Found 2 models about the support for the i1pro & i1pro2 ruler on thingiverse.
The i1pro2 ruler seems like no 5cm edge limits.
How about merge the design to let i1pro running on i1pro2 ruler?
Or even more, convert it to running on the drawing boards slide ruler.
OEM ink for WF-2651 is pigment DURABrite Ultra Ink.
It might be easy to clog, after unplog for a long time.
How do you confirm your new refurbished printhead is not clogged? Did they provide a test print for it?
It might be still have some air inside the printhead path, the worst case might be...
