Customers typically stop complaining once in aqueous form.

I don’t think it’s the same printer/issue but recently my brother printer that I bought in '21 decided it was out of toner and refused print without replacing the toner. I forget what setting I had to find to reset it but it works fine now, on the same toner cartridge I bought with the printer (I don’t print often).

Off the top of my head it was a dcp-l2550dw, can’t check it right now.

It was mildly annoying to deal with, I remember the instructions not working exactly and having to troubleshoot, I can’t recall what I had to do to fix it. I can imagine somebody with less time on their hands just giving in and replacing the toner.
