Only the other day, I purchased a black ink cartridge (the correct one for the printer) and inserted it as normal into the computer. However, when I go to use the printer, it says that the ink cartridge isn’t detected, including the colour one that I haven’t touched and have used frequently since I first inserted it in. It is connected to an iMac computer. Please, do you have any ideas on how I can resolve this ? Many Thanks

Give this a try:
Turn printer off. Unplug power cord and other cables. Wait 30 seconds. Plug cords and cables back in.
take all inks out then uninstall all drivers for printer then place inks back and reinstall the drivers
I have a HP PSC1410v that I had this problem with. It turned out the cartridge itself was bad, even though it was the correct cartridge.
It could also be that you need to clean the contacts on the printer itself.
My model in particular had a problem (I’m not sure if I remember this exactly) that there was a piece of plastic that would bend or break off and actually damage the print carriage contacts. Luckily that wasn’t the problem.
This happens all the time.
It could be the cartridge though it is authentic. The cartridge contacts might be faulty. Take it back to the store and get a refund or another replacement.
