The information icon is constantly flashing

[Rossicat]

The information icon is constantly flashing, can’t print anything. When i icon is pressed printer details sent nothing else. Then it continues to flash.

@Rossicat I suggest you remove the ink cartridges and then try the below steps:

• Turn the printer on, if it is not already on.
• Wait until the printer is idle and silent before you continue.
• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
  • NOTE: 
  • HP recommends connecting the printer power cord directly to the wall outlet.
• Reconnect the power cord to the rear of the printer.
• Turn on the printer, if it does not automatically turn on.
• Wait until the printer is idle and silent before you proceed.

Once done, upgrade the printer firmware using the steps mentioned here,

Let me know how that pans out.
