Hi @Tlegette1 

Welcome to HP Support Community.

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

The error code 0X00829C98 HW WATCHDOG C on your HP printer typically points to a hardware issue where the printer's internal watchdog timer has detected that the printer's hardware isn't responding as expected. This can occur due to a variety of reasons, including firmware issues, hardware malfunctions, or corrupted software. Since you’ve tried restarting/resetting the printer and it still doesn't stay on the menu screen long enough to try fixes, here are some additional troubleshooting steps you can try:

1. Power Cycle the Printer (Hard Reset)

Sometimes, performing a deeper reset can help resolve hardware watchdog errors.

Steps to perform a hard reset:

1. Turn off the printer using the power button.
2. Unplug the power cord from the printer and the wall socket.
3. Wait for 60 seconds. This allows the printer's internal memory to reset and clear any temporary errors.
4. Plug the printer back into the power outlet and turn it back on.
5. Try to see if the error persists.

2. Disconnect External Devices

If you have any external devices connected to the printer (USB drives, external hard drives, etc.), disconnect them to rule out interference.

After disconnecting any external devices, restart the printer again and check if the error goes away.

3. Update Printer Firmware

If the error is caused by a firmware bug, updating the printer's firmware might resolve it. Since your printer’s menu screen isn’t staying long enough to access the settings, you may need to try updating the firmware using your computer.

Steps to update firmware:

1. Download the HP Smart App or use the HP Printer Assistant software on your computer.
2. Open the software and connect your printer.
3. Check for firmware updates under the Printer Settings or Tools section.
4. If an update is available, install it and follow any on-screen instructions.

I hope this helps.

Take care and have a good day.
