Inktank Series 419 Encryption Credentials Have Expired

[Vibhakar1]

I have 2 Series 419 Inktank Printers. The first one installed and has been working perfectly. When I installed the 2nd Inktank, it also installed properly. Can connect to it from one of my MacBooks. But from the MacBook Air, it shows the error:

                                         Encryption Credentials Have Expired

I have tried to delete the printer from the list and add it again - no difference. I connected to the Printer's WebPage - and could print from there as well. It is only from the MacBookAir that I get this error.

Welcome to the HP Support Community!

• Which version of OS is installed on your MacBook Air?

Resetting the printer network settings, reconnecting the printer back to the network and adding compatible driver may resolve the issue. Let's try these steps:

1. Unplug your modem/router and leave it powered off.
2. On the printer control panel, touch "Setup", Touch 'Network Setup", touch "Restore Network Settings".
3. Power off your printer.
4. Reconnect your modem/router and wait for it to re-establish its internet connection.
5. Power on your printer.
6. Run Wireless setup wizard on the printer to connect it back to your network.
