Hi @DonD24 ,
Welcome to The HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand you are facing an issue with the error code "Ox6100004a" on an HP OfficeJet Pro 6978 printer usually indicates a hardware issue.
Here are some steps you can try to resolve the error:
- Restart the printer: Turn off the printer, unplug it from the power source, and wait for about 1-2 minutes. Then, plug it back in and turn it on again. Sometimes, a simple restart can clear temporary issues.
- Check for paper jams: Open the printer's access door and check for any paper jams or obstructions in the paper path. Clear any jams you find carefully.
- Reset the printer: You can try resetting the printer to its factory settings. This can often resolve various issues. To reset the printer, find the reset option in the printer's settings menu or refer to the printer's manual for instructions on how to perform a reset.
- Update firmware: Ensure that your printer's firmware is up to date. You can usually update the firmware through the printer's settings menu or by visiting the HP website and downloading the latest firmware for your printer model.
- Check ink cartridges: Make sure that the ink cartridges are properly installed and are not low on ink. If needed, replace any empty or low ink cartridges.
- Inspect hardware components: Check the printer's hardware components such as the print head, rollers, and other moving parts for any signs of damage or obstruction. Clean the print head and rollers if necessary.
