My hewlet packard's cartridge lite blinks (orange) and the printer won't print. The USB line and power lines are connected. I have shutdown the printer and pulled the power and USB lines, reconnected and repowered the printer and the light still blinks and doesn't print upon command.
I have installed a new cartridge - the proper no's HP78 and HP 15. There is sufficient paper in the tray. The top is closed as tightly as can be.
Any thoughts?
Thanks!
