Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Did you removed the rear cover and checked that area ?
Do you press the reset button on the printer ?
Don't worry just ignore the remote support offer .
Do you see a button like a triangle inside a circle ?
OK, now remove the power cord and wait for 10 mins. after that power on the printer and let me know, what happens ?
Let me know, what happens ?
