Hi @5740a
Welcome to the HP Support Community!
Thanks for posting your query! We're here to help you get back up and running.
The HP OfficeJet 5740 showing a blue screen with error code B808E142 typically indicates a firmware or hardware issue. Here are some steps to troubleshoot:
1. Perform a Power Drain
- Turn off the printer and unplug it from the power source.
- Disconnect all cables, including USB and network connections.
- Press and hold the power button for 30 seconds to discharge residual power.
- Plug the printer directly into a wall outlet (avoid surge protectors).
- Turn it back on and check if the error persists.
2. Update Printer Firmware
- Visit HP’s support page and download the latest firmware update.
- Install the update using HP Smart or the Embedded Web Server (EWS).
- Restart the printer after the update.
3. Perform a Factory Reset
- On the printer’s control panel, go to Settings → Restore Defaults.
- Confirm the reset and wait for the printer to restart.
- Reconnect the printer to Wi-Fi and test printing.
Let me know if any of these steps help!
