Hi and thanks for reaching out. My name is Anthony.
I'm Independent Advisor and I'm happy to assist you.
I understand how difficult it is, when the device or app won't work in the way it should.
It is possible that your computer's operating system may have become unstable, and need to be restarted.
I would suggest to try restarting the computer.
To restart the computer, close all applications running on your computer, save all data, and then turn the printer off.
After restarting the computer, turn on the printer and see if it works.
Hope it will help.
Please let me know if you need any further assistance.
Thank you and Keep Safe.
