Unable to install ink cartridge error 168A tr4520

[ Edited ]

I was getting message about the toner being low, so I decided to go ahead and replace the cartridges. That gave an error "Install ink cartridges correctly" 168A. That was odd because there isn't much to installing them, just push them in until you hear a click. When I kept getting the 168A, I decided to remove the new ones and put the old ones back; that should demonstrate that I was installing correctly. Sure enough, after putting the old ones back I was able to print.


Here are images of the old and the new cartridges and a support message showing that the printer does in fact use the ones that I'm trying to install.


I will be in serious trouble when the cartridges actually are empty.

TIA for you help.
