I have changed my cartridge and alignment paper. There is a blu light flashing in the top left corner and there is O and E white lights flashing on screen. The printer won’t print. The name of the printer is HP envy 6430e. Thank you

@Susan1996,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Let's perform the power drain on the printer:

1> With the printer turned on, disconnect the power cord from the back of the printer and the wall outlet.

2> Press and hold the power button on the printer for 20 seconds.

3> Wait for 60 seconds and connect the power cord back in.

4> This should reset the printer.

a> Check/Wipe Cartridge Contacts:

The "Cartridge Problem" message may be caused by dirt or damage to the gold contacts on the cartridge.

Remove the cartridge and wipe the contacts with a non-fibrous tissue.

If no dirt is visible, use alcohol-based cleaning solution or cartridge flush to remove stubborn marks.

b> Wipe Contacts Inside the Printer:

If the cartridge contacts are clean, the contacts inside the printer may be dirty.

If you can see these contacts, clean them with the same method as before.

Be careful not to leave any tissue scraps inside the printer.

We can update the firmware for the printer, it can be done either on the HP Smart app or on the printer's control panel.
