Canon Pixma MG3650S printer scanner copier

Turns on, but there is an error (yellow light) and I don’t know how to fix it. Free to a tech savvy individual who wants to try and get it working again. The unit has a sticky stain on the outside, I’ve tried to clean it off but you can see the border of where it was.
Comes in its original box, manual and mains cable. I lost the USB cable that comes with this so you’ll need your own, sorry. The cardboard box is a little dusty as it was in storage.
