Why does my printer say ';incorrect color cartridge'; when the correct color cartridge is istalled?

My rather old printer (an HP Officejet G55) has stopped working.


When I try to print, a message comes up on the display, saying I must remove and check the color cartridge. Another message says the wrong color cartridge has been installed.


But the colour cartridge is the right one - an M78. I have used the printer for a long time with the same cartridge in it, and have had no problems.


The only thing I can think of is that the color cartridge is causing a malfunction because I only ever print in black and white.


But I am not a technical person. I could buy a new color cartridge, to see if that works, but they are expensive. Is there any other way of finding out whether the color cartridge is faulty - or is it a loose connection, or is the printer dying?Why does my printer say ';incorrect color cartridge'; when the correct color cartridge is istalled?
Cartridges ';expire';. There is a chip on each cartridge. The chip has good until dates. This is a little scheme cooked up by the printers to stop you from using home refill kits and never buying a new cartridge. I find it evil of the printer makers... but hey, they are trying to make a buck.





If your system is clean, a new cartridge should work.





I would, prior to buying a new cartridge, check the HP site for this error and also send an email to their support to see if the issue is otherwise.Why does my printer say ';incorrect color cartridge'; when the correct color cartridge is istalled?
On the colour cartridge above the electronic strip there should be an expiration date. Over Time the electronics do break down and become less functional. In the case you may get an incorrect cartridge or check cartridge warning. You should try a replacement cartridge before scrapping the printer. Those are the highest capacity cartridge every put on the market and they are certainly a phenomenal value compared to cartridges today.





Your best bet is to try another 78 from a place with a great return policy. This is just in case the secondary cartridge fails you will be able to get your money back. Re manufactured and compatible cartridges are widely available fro that printer and it may be the way to go if you are concerned about cost.





Almost every time you get a check cartridge warning it is because the cartridge is incorrect or the electronics have degraded. In your case it appears to be the latter.





it is a great printer, and worth hanging onto if you can.
Either the printer can no longer recongize the cartridge because something happened to the circuit, or the cartridge for some reason is faulty. First check the cartridge to make sure that the copper ribbion is intact and clean. Reinsert the cartridge and try printing. If that doesn't work, replace the cartridge with a new one and see if that helps. If the same problem persists, then you either get the printer repaired, or simply buy a new printer, if the repair cost is too much.
