Hi @Elohi_NR!

Thank you for your detailed answer!

Could you to clear for me the following:

1. Factory reset. "To perform a factory reset, you may need to access the printer's settings menu"

What does the printer's settings menu? Where should I find it?

2. Perform a Hard Reset:

• With the printer turned on, unplug the power cord from the back of the printer

Do you mean that I have to unplug the power cord when the printer is turned on? Really?

3. Could you advise me how can I contacting HP Support?

Thank you,
