There are some L8050 video manual on youtube.
The easy replacement pickup roller seems nice feature?!
The EPSON EU site seems put much complete info than last week.
ecotank-L8050
180x6 1.5pl
BTW, I already got L3550 just announce end of the 2022. It's precisioncore 4800x1200, but use the same...
The ink I test actually about 100ml for 5usd each here, but seems like an OEM from EV330 on taobao/tmall(about 1.5USD there). I don't sure the same product on aliexpress.
Similar to https://www.aliexpress.com/item/4001188725548.html but this page for HP.
Add another fade test finish recently. 10/18~12/1
Since I am curious about HP GT52 CMY & different combination of GI73+001+673K.
Also test another claim UV resistant dye ink from China as BulkInk EV330
Seems a little strange on the K ink for T673 & 001+673K case, might be ink flush not enough when I switching the cartridge.
on Photo it's EPSON Inkjet paper on top, bottom for 115gsm Inkjet/matte paper.
Besides the worst 003 & 664 K, the high OBA paper seems get Evernew K visible color changed...
After 30days
I have another test on matte paper EPSON 720dpi(Low OBA) & another 3rd Party Paper(High OBA) start at the same date. Post results later.
The Evernew K seems works well on Low OBA paper only.
It's one of the reason why, on my previous tests the Evernew seems not so good.
The 82N...
Which model of the EPSON printer? OEM Ink? Which ink model?
When you print the glossy paper, what paper media selected ?
The L value I would wonder if it's actually pigment K ink.
Prepared new test sets.
All dye inks, no any pigment. The 001/T502 K replaced by T673 K.
Only 1 printer this time: EPSON XP2101
The media type set to Matte STD.
Still tested on 3 papers, besides my original test charts by L365 driver.
Also Apply 96 patches version by WF2010 on HP Premium Plus...
After another 10 days.
EPSON Inkjet Paper(Matte)
200gsm Cast Coated Glossy Paper
180gsm Glossy paper
Based on above results, T673 seem ok to me.
For 4 color dye printer, I would use T673K + T502 CMY for mostly glossy paper usage.
But if main target is matte paper, maybe change to...
Since 114 & 106 might exactly the same as T378 cartridge
Maybe we can reference the SDS from T378 Cyan & Light Cyan ?

There's no lighter color(Easy to notice on C M ) on XP2101 & WF2010 when it's print media select as Glossy paper.(Check previous post#56)
But the lighter C M color by driver only on matte media, not glossy media. So, don't need to consider about GO.
It's like an ink limit for pigment color inks...
Print by XP2101 + T00V(T522) complete CMYK inks + EPSON Premium Semigloss 251gsm photo paper (4x6) SKU s041874
Compare between different drivers & media.
On matte paper media , the drivers designed for pigment black ink or DuraBrite Ultra always smaller gamut & lighter colors.
On EPSON Premium...
Just curious about it, like a puzzle for the weekend.
For the difference in Europe, I would guess it might be some safety or environment limits. So, some versions of the ink need to modify for imports.
Check the WIR again

Sometime, I would check my L800. Especially after I move it.
I never use the valves from 3rd party, so I don't have experience about it could comment.
From the EPSON Ecotank history, The L1800 design might be almost as old as the 1st generation L800.
It seems no one way valve design, so you might need to check the damper sometimes.
After some compare of the SDS exactly match.
T502 K = T512 K = T552 K (Pigment)
T774 = 102 K = 105 = 114 K (Pigment)
114 = 105 & 106=378(CMYK) [But 114 Grey is not the same as 478 Grey from XP-15000]
T552 != T512(only exception: Pigment K is the same)
102 != T502 != T522 != 103/104
