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.
In my teens my parents used to have ink printers. I remember EPSON big, gray and heavy printer/scanner combo that always had issues with either USB or ink. I hated to use that one.
A recent one is a HP (I think) ink printer at my moms. Her’s had an issue where ink cartridge would be new but it would print empty pages. Turns out ink in tubes dried up and clogged everything. I told her to get new one but she said she already had a stock of ink for this one and it would be shame to lose all that money. This shit ink is the most expensive liquid on earth after all. I tried to fix her’s but it deemed to be impossible so we talked and she got same but used one. She will use up all her ink and I’ll get her a good one after.
I will not buy her HP or EPSON in my life!
