I was able to remove the CIS cartridges without getting the error by holding down the printhead very firmly as I unclipped and removed the ink. After I removed it, I then re-seated and clicked the ink cartridges back into place and clicked "Start". The printer then does a check but goes back to the screen that says, "Cannot recognize cartridge(s). Try installing them again."
What can I do now? It's not going to the screen where it tells me I am using unofficial ink cartridges.
