Hi @Stegor8 

Welcome to The HP Support Community.  

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

I understand you're dealing with a frustrating issue with your HP OfficeJet Pro 6978 printer. The error code 0x6100004a usually indicates a hardware problem or a communication issue between the printer and the computer. 

Here are some steps you can try to resolve the issue:

• Restart the Printer: Sometimes, a simple restart can clear out temporary glitches. Turn off the printer, unplug it from the power source, wait for a few minutes, then plug it back in and turn it on again.
• Check for Paper Jams: Even if you've already checked, go through the paper path again to ensure there are no small shreds of paper stuck anywhere. Even the tiniest piece of paper can cause errors.
• Reset the Printer: You can try resetting the printer to its default settings. To do this, find the reset button on your printer (usually a small hole that you can press with a paperclip) and press and hold it for about 10 seconds. Refer to your printer's manual for specific instructions on how to perform a reset.
• Update Printer Firmware: Sometimes, updating the printer's firmware can resolve various issues. Visit the HP website, locate the support section for your printer model, and download the latest firmware update. Follow the instructions provided to install the update. Update the firmware on an HP printer
• Check Ink Cartridges: Ensure that the ink cartridges are properly installed and are not empty. If you suspect that a particular cartridge might be causing the issue, try removing it and restarting the printer to see if the error persists without that cartridge.
• Check for Software Issues: If you're trying to print from a computer, ensure that the printer drivers are up to date. You can also try uninstalling and reinstalling the printer drivers to rule out any software-related issues.
