Hi @Muin07 

Welcome to HP Support Community.

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

The error code ED.56.E6.57 on your HP OfficeJet Pro 9730 indicates a critical system error. Here are some steps you can try to resolve the issue:

1. Restart the Printer

1. Turn off the printer.
2. Unplug it from the power source.
3. Wait for about 60 seconds.
4. Plug it back in and turn it on.

2. Update Printer Firmware

Make sure your printer's firmware is up to date. Since you’re using a MacBook, here’s how to check for updates:

1. Open HP Smart on your Mac.
2. Select your printer.
3. Go to Printer Settings or Manage Your Printer.
4. Check for any firmware updates and install them.

3. Check for Paper Jams and Obstructions

• Inspect the printer for any paper jams or foreign objects. Clear any obstructions you find.

4. Reset the Printer to Factory Settings

If restarting doesn’t help, consider resetting your printer:

1. Go to the Control Panel on the printer.
2. Navigate to Settings > Printer Maintenance > Restore Factory Defaults.
3. Follow the prompts to reset.

I hope this helps.

Take care and have a good day.

Hi Rachel,

I've followed the instructions in the first point, but unfortunately, I’m still getting no results. As for the second point, I checked the printer's firmware, and it’s confirmed as up to date. Regarding the third point, there is no paper jam or any obstruction.

The only step I haven't been able to complete is the fourth, as the error on my HP OfficeJet Pro 9730 remains on the screen and cannot be cleared, which means I cannot access the Settings > Printer Maintenance > Restore Factory Defaults section.

Could you please assist me, given that I live very far from the HP Office Center? It would take four days by boat to get there, and I urgently need to print. Thank you very much for your help.

Best regards,
Muin
