One that’s happy with a refilled toner.

Here’s the challenge. Is it possible to create a refilled/remanufactured toner cartridge as good as an original? Absolutely! Is the one you’re buying meet that standard? There’s no way to tell.

You could have bought a garbage refilled toner where the company did less than the minimum needed for it to function. There’s no standards body for these. The best you can do is buy from a company known to do good reman work. If you work at a company that still has a fleet of printers, and your IT team still maintains them, ask what brand they use.
