Hey
Welcome to the HP Support Forum. 
I see that you're encountering a recurring error state in your HP Deskjet 3050 All-in-One Printer. I would like to assist you with this.
I recommend you perform a 'hard reset':
1. Ensure your printer is powered on.
2. Disconnect the power cord from the rear of the printer.
3. Wait 60 seconds.
4. Reconnect the power cord to the rear of the printer.
5. Press the Power button to turn on the printer if it doesn't automatically reboot.
If this doesn't help, I suggest you reach out to our tech support team. You can click on the following link to initiate a case: www.hp.com/contacthp/
Once you fill out the online form to create your case you can choose from different direct contact methods.
Let me know how it goes. Thank you for posting in the HP Support Forum.
Have a great day!
