HI @nan110,

Welcome to HP Support Community.

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

Error code B84986B8 on your HP Officejet 5740 e-All-in-One printer typically indicates a firmware or hardware issue. Here are steps you can take to try to resolve this error:

Troubleshooting Steps:

Power Cycle the Printer:

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

Check for Firmware Updates:

• Ensure your printer has the latest firmware installed. You can check for firmware updates through the HP Smart app or the HP website.
• Download and install any available updates.

Reset the Printer:

• With the printer turned on, disconnect the power cord from the back of the printer.
• Unplug the power cord from the power source.
• Wait for about 60 seconds.
• Plug the power cord back into the power source and reconnect it to the printer.
• Turn the printer on.

Remove and Reinsert Ink Cartridges:

• Turn off the printer and open the ink cartridge access door.
• Remove the ink cartridges and inspect them for any damage or ink buildup.
• Clean the electrical contacts on the cartridges and inside the printer with a lint-free cloth.
• Reinsert the cartridges and close the access door.
• Turn the printer back on.

Check for Paper Jams and Obstructions:

• Ensure there are no paper jams or obstructions inside the printer. Carefully inspect all accessible areas, including the paper feed and output trays.

Reset to Factory Defaults:

• If the error persists, you may need to perform a factory reset on your printer. This will reset all settings to their defaults and may resolve the issue. Consult your printer's user manual for instructions on how to perform a factory reset.

I hope this helps.

Take care and have a good day.
