Did you unplug printer and remove the cartridges and then put back in and plug it back into wall?
Also open the printer and see if the carriage moves from side to side, if not their should be a plastic piece on one side. See if you can click the platic piece down very gently to get the carriage to move from side to side to clear up the jam.
Please reply back here when you are finished.
Also go through the normal steps about nozzle cleaning and head cleaning from your menu on your printer. Just to rule out if their is a tiny piece of paper stuck on carriage.
Keep me posted in this chat by replying to chat.
Good morning, just wanted to know if you need anymore help?
