I would recommend checking the levels of the ink to be your first step. If they appear to be fine then you may need to replace the printhead. You can see our guide on how to replace the printhead. If your levels of ink are low you should replace the ink cartridges which is also shown in our guide.
Hello Laura, Your issue could be a variety of things but my first thing I would like you to check is if your power cord is connected to a working wall outlet. If this is not the case then you should check if your power module & battery are working. Please check out my troubleshooting guide for more help. If you have any more issues, feel free to ask me another question
