Erro code oxb857c6b4

[Sofia_182]

Hello, a few days ago my printer OfficeJet 6950 started to display this error code: oxb857c6b4 and all the icons blink.
To reset the printer I need to remove the plug and wait a few seconds before reconnect the plug.
Unfortunately, this is not a final solution, as the problem reapper after a few hours.
Can you please help me fix this? Thank you
