I can't change the cartridges because there isn't a way to move them to the front without the machine actually knowing they're empty, right? So...now my machine is stuck and I can't really print anything on it. How do I fix this? Is anyone else in this spot?
If the ink tank has a question mark on it, it will mean the tank is malfunctioning and the printer can't detect the current ink level. The Maxify printer will not move the ink to the changing position unless the printer detects that the ink is empty.
In this situation, you can try deep cleaning the black ink until the ink starts to flow again or the level for the black ink reads as empty. If you are using a third party ink tank, the tank could be the issue and you can check with the company that made the tank to see how to manually remove it.
