**HP “Setup mode”** typically refers to a state where the printer is ready to be configured or connected to a wireless network, often called Auto Wireless Connect (AWC) mode or wireless setup mode. In this mode, the printer allows the user to connect it via the HP Smart app or other setup tools to join a Wi-Fi network.

To enter **HP printer setup mode** (wireless setup/Auto Wireless Connect mode):

– Press and hold the **Wireless** button on the back of the printer for about 5 seconds.
– The printer’s LED or Edge lighting should pulse purple, indicating it is in setup mode ready for network connection.
– Then use the **HP Smart app** on your phone or computer, connected to the same Wi-Fi network, to finalize setup. Bluetooth may be used by the app to speed the process on mobile devices.
– If the printer is stuck or won’t enter setup mode, try connecting it to a computer via USB for setup or perform a restart/factory reset[2][1][4].

If the printer is **stuck in setup mode**, you can try these:

– Press and hold the Wireless button for 5 seconds to reset network defaults.
– Use the HP Smart app to reconnect.
– Press the Wireless and Cancel buttons together for 3 seconds to exit setup mode.
– Restart the printer and ensure firmware is updated.
– Check for paper jams or other hardware issues[2][4][1].

For a **factory reset** (full settings reset), refer to your printer’s manual as the steps vary by model. This will erase all settings and return the printer to default, which can help resolve setup mode issues[1].

In summary, HP setup mode is mainly the wireless network setup state initiated by holding the Wireless button, enabling easy Wi-Fi connection using the HP Smart app. Troubleshooting involves resets, using USB connection, and ensuring the app and printer firmware are current.
