ERROR: supply system problem

[avi131]

The printer HP Office Jet Pro 7740 does not work. The printer gave an error that the black
cartridge is empty. I replaced it with a new original one, but the error
remained, I installed the new original one again, but it didn’t help. Despite a factory reset and
updated the drivers the error remains.
I ask for your help.

Hi @ Avi131,

Welcome to HP Support Community.

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

I'm sorry to hear that you're experiencing issues with your HP OfficeJet Pro 7740. If you've already replaced the black cartridge with a new original one and performed a factory reset without success, there are a few additional steps you can try to resolve the issue

1. Restart the Printer:
• Turn off the printer, unplug the power cord, and wait for about 60 seconds.
• Plug the power cord back in and turn on the printer.
2. Check for Paper Jams:
• Make sure there are no paper jams in the printer. Open all access doors and remove any paper that may be stuck.
3. Check Connectivity:
• Ensure that all cables are securely connected to the printer.
• Check the wireless connection if you are using Wi-Fi. Make sure the printer is connected to the correct network.
4. Update Firmware:
• Check if there are any firmware updates available for your printer on the HP support website. If so, update the firmware following the manufacturer's instructions.
5. Reset the Printer:
• Some printers have a reset button or sequence. Check the printer manual for instructions on how to perform a reset.
6. Factory Reset:
• As a last resort, you may consider performing a factory reset on the printer. Be aware that this will erase any custom settings you have made. Refer to the printer manual for instructions on how to perform a factory reset.
