Hi@Hamza28,

Welcome to the HP Support Community! I'd like to help!

I see you are experiencing issues with the HP Smart gets error when login.

Are you able to print using the app?

Try the steps below:

1) Restart your phone and the printer and then check if the issue occurs, try a browser to login to HP Smart web         account

2)Uninstall the app and restart your phone

3) Install the app and try again

I have a few recommendations 

• The firmware must be updated first if an older version is installed, else the reset will not be made..

• You will need to follow the instructions below to reset printer:

• Turn the printer off.
• Press and hold down the Color Copy and the Resume buttons.
• Hold the buttons when you turn on the printer.
• When the all light turns on, release the Color Copy and the Resume buttons.
• NOTE: It takes about 60 seconds before initialization process begins.
• The initialization starts.
• When the initialization completes, the printer enters the generic printer mode.  

Hope this helps! Keep me posted.
