HP OfficeJet 4630 Error at startup

[ap230958]

Hello, I am getting different errors on startup of my printer. They include: OXB8025F92, 0XB80267C5 0XB80005F4 0X007C9C98 HW_WATCHDOG C, AND 0X83C0000A NOS_LOADER_APP. The NOS_LOADER_APP error is most common when I start the printer. The printer is unable to bootup because of these error codes. Please help!

@ap230958,

Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Restart the Printer

• Turn off the printer.
• Disconnect the power cord from the back of the printer and from the wall outlet.
• Wait for about 60 seconds.
• Reconnect the power cord to the wall outlet and the back of the printer.
• Turn on the printer.

Check for Paper Jams

• Open the printer and check for any paper jams or obstructions. Remove any stuck paper carefully.
• Inspect the printer's feed path for small pieces of paper or debris.

Check the Printhead

• Turn off the printer and open the ink cartridge door.
• Check if the printhead or cartridges are installed properly.
• If needed, try removing and reinstalling the cartridges.
• Clean the printhead if you notice any ink buildup or debris.

Update or Reinstall Printer Drivers

• Ensure your printer’s firmware is up to date. You can check HP’s website for the latest version and update the printer if needed.
• Try reinstalling the printer drivers on your computer as outdated drivers can sometimes cause communication errors.

Perform a Reset on the Printer

• You can try a factory reset, which can help if there’s a software issue causing the shutdowns.
• To reset the printer, go to the printer’s control panel, select "Setup," then "Printer Maintenance," and look for a "Restore Defaults" or "Reset" option.

Check Ink Cartridges

• Ensure that the ink cartridges are properly installed and have sufficient ink. If any cartridge is low or empty, replace it.

Check the Power Supply

• Ensure the power cord is securely plugged into both the printer and the wall outlet.
• If the printer is plugged into a power strip or surge protector, try plugging it directly into the wall to rule out any power issues.
