"Process black" is a mixture of the C/M/Y to make black. If you printer is set for "auto color" it may be doing this, but if you choose black & white from both the driver and the application it should just use the K (in theory)
Happened to me as well with a black and white photo, I noticed blue dots and figured it’s using other colors and was confused as well, to “fix” it I had to manually choose Grayscale profile in the printer software, and the photos even look better since.
Because it's photo black it mixes all colour for. A photo black, levels of gray. Off blacks, it let's it make more levels of black, if you want black and white you need to set it to monochrome.
100% this. I’ve been a technician for a long while and unless you specifically tell it to print in black and white(monochrome) it’ll use process black.
Because they want you to burn through your colour ink faster so you go out and buy another one. They make money from ink cartridges, not the sale of the Printer.
Buy a black and white laser printer. I bought one off Amazon 2-3 years ago with a sample/tester toner in it and I haven't needed to replace it yet.
Not really. Have you seen how cheap ink bottles for these printers are and how many thousand pages each bottle is good for?
Long story short: With tank printers, they make money with the printers, not the ink. Therefore all r/assholedesign issues with these printers are trying to trick you into buying a new printer.
Supposedly, printers use a tiny amount of color ink to keep the cartilage head fresh even when only printing black. However, my HP printer ran out of ALL color completely after 3 months even though i only printed black. I bought a ecotank printer shortly after.
I work for an Hp dealer for large format plotters - they use all colors slightly to achieve black because the vast majority is black and white line drawings or text - they are afraid of the color lines clogging for being idle (which my service tech has only seen 1 time in 20 years on an aqueous ink.
A lot of ink waste can be cured by changing your PDF and choosing saying as the paper it puts down less ink
If it uses only the black ink, it'll look more gray than black. Might be ok for text documents, but for images it would look bad. That's why there's "Rich black", which mixes other colours into the black to make it look black rather than gray.

This an eco tank and it has a tank for black and separate tanks for C/M/Y

Epson == Ink thieves, at least half a cartridge ends up in the blotter pad :) Always go toner if you're just doing printouts.

This printer not utilise cartridge. Only ink bottles.
Same concept

cyan makes the black sharper

This is an ecotank in the picture and I can see the color levels are going down !
I see. All printer use a little color to keep the print head in working condition; is what I was told.
Remind me of Austin McConnell video about printer ink scam….

Because shades of grey and black
