@Laura385, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding a problem with your printer!
We're thrilled to have the opportunity to assist you and provide a solution.
The error code 0x6100004A on your HP OfficeJet Pro 6968 usually indicates an internal hardware issue, often related to the printhead, ink system, or a mechanical problem. Since you've already performed basic troubleshooting (power cycling, unplugging, and checking for paper jams), here are some additional steps you can try:
1. Reset the Printer (Hard Reset)
- Turn on the printer (if it's off).
- Disconnect the power cable from the back of the printer while it's still on.
- Unplug the power cord from the wall outlet.
- Wait at least 60 seconds.
- Plug the power cord back into the wall outlet first.
- Reconnect the power cable to the printer.
- Turn the printer back on and check if the error persists.
2. Check the Ink Cartridges & Printhead
- Open the printer’s cartridge access door.
- Remove the ink cartridges one by one.
- Inspect for any ink leaks, damages, or improper installation.
- Gently clean the printhead contacts using a lint-free cloth dampened with distilled water.
- Reinsert the cartridges properly and close the door.
- Restart the printer and check if the issue persists.
3. Perform a Printhead Cleaning (If Accessible)
If your printer allows manual printhead cleaning:
- Open the printer lid and check for the printhead assembly.
- Remove and clean it carefully using a lint-free cloth and distilled water.
- Let it dry completely before reinserting.
4. Update Printer Firmware
- Go to HP’s official support site: HP Support
- Search for HP OfficeJet Pro 6968.
- Download and install any available firmware updates.
Hope this helps!
Take care, and have an amazing day!
