Blinking orange lights deskjet 2734

[Jg371]

When I turned on the printer, the on/off light blinks continuously and orange lights are also blinking at the cold cartridge, the paper indicator, and the i indicator. The window is blinking with a double E and all other indicators. I’ve reset the router and printer several times. I’ve also taken the ink cartridges out and reseated them, and put a new color cartridge in. I just replaced the black cartridge a couple of weeks ago, and have done very little printing. Any help would be appreciated

Hi @Jg371,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue with your HP DeskJet 2734e displaying a combination of error indicators. Lights blinking

Here’s a step-by-step guide to help you troubleshoot the issue:

Check for Paper Jams:

• Open the printer's access door and look for any paper jams or obstructions. Remove any paper or debris carefully.

Check the Ink Cartridges:

• Ensure that both the black and color cartridges are properly installed and seated correctly. Sometimes, even a small misalignment can cause issues.

Reset the Printer:

• Unplug the printer from the power source. Wait for about 60 seconds, then plug it back in and turn it on. This can sometimes resolve temporary errors.

Check the Ink Levels:

• If you have an HP Smart app or a similar utility, check the ink levels to ensure there isn’t a low ink issue.

Clean the Cartridges:

• If the issue persists, remove the cartridges and clean the electrical contacts on both the cartridges and inside the printer gently with a lint-free cloth.

Perform a Hard Reset:

• Turn off the printer and unplug it from the power source. Wait for 60 seconds, then plug it back in and turn it on.

Check Printer Status:

• Look at the printer’s display or indicator lights to see if they show a specific error code or message. Refer to the printer’s manual for details on what each error code means.

Firmware Update:  Update the firmware on an HP printer

• Sometimes, updating the printer’s firmware can resolve issues. Check if there’s a firmware update available for your model on the HP website.
