Hello sinema, and welcome to the HP Forums, I hope you enjoy your experience!
I see you are having color output issues. I would like to assist!
I would recommend performing a power reset. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I would also suggest following the steps in this document on Resolving Print Quality Issues.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!
