After replacing the Black toner cartridge in the Konica Minolta magicolor 2530 the printer flashed up not genuine toner cartridge, then displayed Yellow not installed , Cyan not installed, Magneta not installed.... it thinks that no toners are installed. As it said the black was not a genuine cartridge i put the previous empty black back in.
The printer still displays that the color toners are not installed. It will not rotate the toners (only when you slect replace a toner) otherwise on its own they rotate, it doesnt say black isn't genuine anymore but still won't let you print. And says the toners are not installed, but they havn't been moved. The colors are full.
This is actually a desigbn fault on the magicolor printers. Underneath the toner rack is the 3 pin chip reader - normally white and plastic with 3 metal contacts sticking out.
it is at the bottom of the printer so very often toner drops onto it and the sensors dont work, it also takes a bit of a beating as the cartridges rotate. Its very easy to replace - but you need the part,
Minolta should have put it at the top rather than the bottow where it gets covered in dust.
these guys helped me a lot

Pleas clean toner chip reader, remove pc drum and all toners, under the toner rack there is a 3 pin chip reader, use pressure air to clean it. if the new BK toner is not original, it will say only not genuine toner but will print.
In fact from the menu (I have magicolor 2530 which is a new declination of 2400W) I was not able to remove all cartridges: after having one taken the printer does not want to rotate anymore to access others. I made them rotate manually pushing vigourously the rotating system but I believe it is not a good solution. After that I could access the sensor and clean it and it works. I discovered a better solution: After removing the drum, without removing the cartridges the sensor is half vesible: we see on the right just beneath the cartridges a white plastic square and we jave just to intruduce a little brush or a bit of paper towel folded in four over it to clean it.
