Turn it off for a minute and turn it back on then reinstall all the cartridges back into your printer. When installing, make sure you won’t knock out the previously installed cartridges and make sure they are all sitting tightly inside the correct slot. Give them a little push if you have problem installing.
removed. Also check the bottom of the cartridge to see if the plastic cover is being penetrated. If the plastic cover is not being penetrated, please in a safe area, use a pointy object (like pen, hair pin, toothpick etc) and gently penetrate it. PLEASE DO NOT remove the plastic cover fully, it might leak and make a mess inside the printer.
Then reinstall the cartridges make sure they are sitting properly inside the printer.
