@steffies314, Welcome to HP Support Community,

 

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

 

If all the lights on your HP DeskJet 2734e are flashing, it typically indicates a general error that requires attention. Here are steps you can take to troubleshoot and resolve the issue:

Restart the Printer:

  • Turn off your printer using the power button.
  • Disconnect the power cord from the printer and the power outlet.
  • Wait for about a minute, then reconnect the power cord to the printer and the power outlet.
  • Turn on the printer and check if the lights continue to flash.

Check for Paper Jam:

  • Open the printer's front and rear access doors to check if there is any paper jammed inside.
  • Carefully remove any paper or foreign objects.

Verify Print Cartridge Installation:

  • Open the cartridge access door and ensure both ink cartridges are properly installed.
  • Reinstall the cartridges if necessary, ensuring they click into place.

Check for Error Messages:

  • If your printer is connected via USB to a computer, check your computer for any error messages that might give more details about the issue.

Ensure Correct Ink Cartridges:

  • Make sure the ink cartridges are compatible with the HP DeskJet 2734e and are not low on ink.
