@nathans My 90yo neighbor called me and asked if I could help her because her printer stopped working.

"Who made it?" I asked

"Epson" she said.

"I'll be right over. If you have the manual, I'd like to see it." I sighed with relief.

She didn't. But I got it working just by using the front panel and running the cartridge cleaning cycle a couple times.

I didn't relish telling her to throw out her printer and buy a new one, although I did mention that a $100 Brother laser printer would probably be less trouble.
