Question about Printers & Copiers
First thing to do (if not yet done so) is to access the printer through the web admin interface by typing the printer's IP address in a browser. This gives a lot more information than the blinking lights.
The Status page of the web admin interface may say "toner low" or "toner empty" or "error on toner sensor" and that will tell us which color cartridge to handle.
Note that the OKI 3400n has the annoying tendency to fail when loading in a new toner cartridge: a color is low or empty, you put in a new color tube and then the printer says error on that very color! This can be fixed by pulling out the drum of that color (the drum is that entire block which includes the color tube and the container below it; avoid touching the shiny green roller), and lightly tapping on that drum to evenly distribute the new powder inside the container.
You may have noticed that the once the color tube is loaded in, what it does is to empty its content into the container below. Which means that it's no use swapping color tube once it's installed because the color tube is empty by then, and is just kept there to prevent the ink powder from spilling out of the container. The caontainer itself has 5 electrical contacts on its side used to measure the powder content and the lifetime of the drum.
