Hi MKazi,
Thank you for the response.
When I try to make a copy using the scanner glass bed, the screen shows "Starting Copying" message and gets stuck on that forever. I don't hear any sound in the printer at all. Hitting the X cancel button does not do anything.
When I tried to reboot the printer by pressing the power button off and then on, I got a weird screen. A blue screen showing the power symbol (i.e. circle with a vertical link in the middle) with the following code below it: 00759C98 and all the lights of the buttons on both sides of the screen are blinking. Check it here: https://photos.app.goo.gl/TXS7nKJXnsuMBuP23)
I tried to reboot the printer multiple times by pressing the power button. That didn't help.
I disconnected the power cord from the back of the printer, waited for 60+ seconds, then reconnected the power cord back. When the printer rebooted, I got a message stating "Unable to scan, copy or send a fax". The title of that screen read "Scanner Failure"... Trying to copy again gave me the same screen.
Then, I followed the instructions listed below. I got the same error message "Scanner Failure" again. I didn't see the bulb illuminating.
