Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Are you using an Apple Mac or Windows PC ?
How is the printer connected to your computer ?
Please don't open new questions. Instead please reply here, so I can help you
This usually happens if there is any issue with the cable or if the printing system is glitched. First we can reset your printing system and see if it works or not.
After resetting,your Printer will disappear from the list. So disconnect the printer from your Mac. Turn the printer off and unplug it from Power for 2 minutes. Plug it back and connect it to a different USB port of your Mac. Then in Printers and Scanners window, click the + button (in left corner) and add it back.
Please let me know if that didn't work, so we can continue troubleshooting.
