@Arun297, Welcome to the HP Support Community – it’s great to have you here!

I appreciate you taking the time to share your question. I'm more than happy to assist with this and provide a solution that works for you.

If all the lights on your HP DeskJet 2752e are flashing and the printer is not connecting to the HP Smart app, it usually indicates a connection or firmware issue. Let’s walk through the steps to fix it:

Power Reset the Printer

This clears temporary errors.

  • With the printer powered on, unplug the power cord from the back.
  • Unplug it from the wall outlet too.
  • Wait 60 seconds.
  • Plug it back in and turn it on.

Check if the lights stop flashing.

 

Restore Network Settings

This resets Wi-Fi settings so you can reconnect.

  • Press and hold the Wireless button and the Cancel button together for 5 seconds.
  • The printer will restart and enter setup mode (blue light should blink).

Reconnect Using HP Smart App

Make sure you’re using the latest version of the HP Smart app.

  • Download or update the app: HP Smart
  • Open the app and tap “+” to add a printer.
  • Follow the on-screen steps to connect your printer to Wi-Fi.

Ensure your phone is connected to the same Wi-Fi network you want the printer to use.

Update Printer Firmware

Outdated firmware can cause flashing lights.

  • Go to: Official HP® Support
  • Enter your printer model (2752e) and download the latest firmware.
  • Install it using your PC or HP Smart app.

Factory Reset (if needed)

If nothing works, a full reset may help.

  • Press and hold the Wireless and Cancel buttons for 20 seconds.
  • This will reset the printer to factory defaults.
