Got a printer at the warehouse where they sell used hotel equipment. They told that it has a defect in a way that it "prints with a line across". All cartridges were full and working. And it seems that they can be refilled judging by the area around the caps.
It did work but the "line" was a bend, not a print. Found out that heating roller in a fuser was the culprit. Was about to get a new fuser off Alibaba for a 100 but my wife gave me a better option. She suggested to get a used one off local marketplace. We found same lineup smiplier model with empty cartridges. After a quick swap, this little boy now gives out sharp and plain prints. 30 euro for defective office one, 40 euro off marketplace.
This pic is from a marketplace printer with a swapped in defective fuser.
P.S. Apparently, this brand has an extensive servicing manual for this lineup printers. It has all instructions for servicing pretty much any part with pictures and videos. Major props for Lexmark. Never heard of this brand before.
I agree. They enshittified themselves out of the market with their subscription service for ink.
They took on more consumer hostile practices over time, but that was a big one.
