A very warm welcome to the HP community. A very good day to you.
I understand that you have an HP OfficeJet Pro 8710 All-in-One Printer and the color copies do not copy exact color. Not to worry, I'll do my best to help you.
I would like to know the following information to assist you better:
- How is color output while printing documents?
- Have you tried to copy from the ADF (Automated Document feeder) and the scanner glass bed and checked if there is a difference?
- How is the scan output? Does it have the exact colors?
Meanwhile, I recommend you to perform the following steps to isolate the issue and arrive at a fix:
- Disconnect the power cable from the printer while the printer is still ON.
- Disconnect any other cables if connected the printer.
- Press and hold the printer’s power button for 15 seconds.
- The printer should be directly connected to the wall outlet and not to a surge protector. Reconnect the power cable to print and the printer should power ON by itself. If the printer doesn’t power ON then please manually power it ON.
I suggest you to also refer to this HP Document and perform the steps as described in detail.
I hope this information helps. Please feel free to let me know what happens. Cheers! 🙂
