Hi! @Caliope17, Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!

I understand you are getting the printer was not shut down properly C9C70000 error on your printer.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Try the steps recommended below.

In some cases, removing the ink cartridges and resetting the printer can clear the error message.
Turn on the printer.
Wait until the printer is idle and silent before you continue.
Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.
Remove the ink cartridges from the printer.
With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.
Wait at least 60 seconds.
Plug the power cord back into the wall outlet.
   NOTE:
HP recommends connecting the printer power cord directly to a wall outlet.
Reconnect the power cord to the rear of the printer.
Turn on the printer, if it does not automatically turn on.
The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
Reinsert the ink cartridges, and then close the ink cartridge access door.
If you receive a prompt to print a calibration page, do so.
If you disconnected the USB cable, reconnect it to the rear of the printer.
Try to print.

If the issue still persists try updating the printer firmware and check if it helps.

Update the printer software using this link.

Let me know if this works! 
Have a great day ahead! 🙂

Unfortunately this did not work.  I keep getting the same message.  I'm not sure that it is not a problem with the

cartridge mechanism, as it does not move on it's own into a position where the cartridges can be removed it seems

to be stuck to the right even after the cover is opened to remove the cartridges.

This is so disappointing. I know that our company buys many HP products and this is a new printer that I had for only

3 days when this started to happen.

Do you have any further suggestions, it would be most appreciated.  If not, thanks so much for attempting to assist with this issue.

@Caliope17, It's great to hear from you again.

I appreciate your efforts for trying out the steps.

As you mentioned the issue still persists after trying out the steps.

I understand your concern, but it is a hardware issue with the printer, please contact HP support for service options.

Link to contact HP.

Have a great day ahead!

Take Care! 🙂

Having the same exact issue. Have contacted HP support to be told it has to do with my laptop (not true) printer has an error c9c7000 and not connected to laptop. Then I was told I’d have to pay for support. Why would I pay when hp printer doesn’t work?

The steps worked when I made sure to unplug the power cable from the back of the printer and then go out for coffee before trying it again.
