My printer stopped working, but it used to print. When it is attached to the charger and plugged in, it appears to be charging, often showing a green light. However, when I unplug it, it will not turn on, and when I plug it back in, it shows a red light, no matter how long I have previously charged it for. I have tried resetting the system with no luck, and additionally my printer will not function or connect to my phone when it is plugged in and charging. Please help!
