Screen reads "Near empty Cyan" but I just replaced... (by 4 users)

If the firmware update doesn't work, you can reset this error.

Unplug unit. Remove offending cartridge. Plug unit back in, wait until all startup noises have stopped. Open lid and reinstall cartridge. This will solve the fault as long as the sensor is working.

Also, please be aware, you should not have to change a cartridge if it says "Near Empty", only if it says "Ink Empty Magenta".

Also, please make sure none of your other cartridges are empty. I have seen this over and over. Two cartridges empty at the same time, and the person replaces one of them but thinks they actually replaced the other one.

Turn the power off and pull all the cartridges out. Look a the side of the cartridge, you should see a window with a little plastic tab sticking out. This tab should be blocked by a black float inside the cartridge. If you cannot see the float, and the tab is clear with no ink in it and no float tab blocking it, it means the cartridge is empty even if you still see some ink in the bottom.

To be sure plug the machine in without any cartridges. When all the noises have stopped, open the lid and install the cartridges. If you're still getting an error saying either a cartridge is not installed or is empty, then one of your cartridges is empty. Redo the previous paragraph.
