The error 0XB039E5A0 on your HP OfficeJet 2620 printer is typically related to firmware issues, ink cartridge problems, or a system error. Try the following troubleshooting steps in order:
Power Reset the Printer (Basic Reset)
- Turn off the printer using the Power button.
- Disconnect the power cord from the printer and the wall outlet.
- Wait for 2-3 minutes to discharge residual power.
- Plug the power cord directly into the wall outlet (avoid surge protectors).
- Turn on the printer and check if the error persists.
Check for Paper Jams or Obstructions
- Open the printer’s front cover and inspect for any paper jams.
- Remove any jammed paper carefully.
- Close the cover and restart the printer.
Remove and Reinstall Ink Cartridges
- Turn on the printer and open the cartridge access door.
- Wait until the carriage moves to the center.
- Remove the ink cartridges (both black and tricolor).
- Clean the cartridge contacts using a lint-free cloth slightly dampened with distilled water.
- Let them dry, then reinstall the cartridges and close the access door.
Perform a Semi-Full Reset (Advanced Reset)
A semi-full reset restores factory settings and clears most errors.
