How many cartridges do color laser printers need? How long do they last?
There is only one drum cartridge and four color cartridges. The drum outlasts the colors by years. We have changed the color four times and the black even more and are still on the same drum. I was having a problem and thought it was the drum and it wasn't. I forget how I solved the problem but I put the old drum back in and have the new one in a box. Did you buy the printer? Did you install the software and have the K on you desktop? If so you can look to see what percentage is left on your drum kit as well as your inks.
