This toner was changed over in a little over a minute and so far works perfectly. In my experience this lasts a long time and I have used it for about 2 years before they started running out. It's quite expensive but that's printer ink for you

It's a printer cartridge. It lets me print things.

No compatibility Issues

Todo perfecto
