Hi @Sdk11005,

Welcome to HP Support Community.

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

When all the lights on your HP DeskJet 2755e printer are flashing, it usually indicates a general error or a problem that needs addressing. Since you just replaced a cartridge, the issue might be related to the cartridge installation. Here are some steps you can follow to troubleshoot and resolve the problem.

Power Cycle the Printer:

• Turn off the printer.
• Unplug the power cord from the printer and the power outlet.
• Wait for about 60 seconds.
• Plug the power cord back in and turn on the printer.

Check Cartridge Installation:

• Open the printer's cartridge access door.
• Ensure the cartridges are properly seated and securely clicked into place.
• Remove the cartridges and reinsert them to ensure a proper connection.

Clean the Contacts:

• Turn off the printer and unplug it from the power source.
• Open the cartridge access door.
• Remove the cartridges.
• Gently clean the electrical contacts on the cartridges and inside the printer using a lint-free cloth slightly dampened with distilled water.
• Allow the contacts to dry completely before reinserting the cartridges.

Update Printer Firmware:

• Make sure your printer’s firmware is up to date. You can check for updates on the HP website or through the HP Smart app.

Reset the Printer:

• Press and hold the power button for at least 15 seconds.
• Release the power button and wait for the printer to reset.

Check for Obstructions:

• Ensure there are no paper jams or obstructions inside the printer.
• Check the paper path and remove any debris.

Check Cartridge Compatibility:

• Ensure the replacement cartridge is the correct one for your printer model.
• Sometimes, non-HP cartridges or refilled cartridges can cause issues.

Reinstall Printer Software:

• Uninstall the printer software from your computer.
• Download the latest version of the printer software from the HP website.
• Reinstall the printer software.

I hope this helps.

Take care and have a good day.
