Hello, and thank you for using this service.I will help you now.
Please inspect and clean the inside of the printer with a flashlight. Pay close attention to the carriage area. If you have compressed air, use it to further clean out the inside of the printer. Remove all ink cartridgles, and reinstall. Finally, unplug printer, and hold power button down for at least 30 seconds. Then plug back into power. Let me know results of these steps. Thanks.
