Error code C9C70000 - HP OfficeJet Pro 6960

[nijagaw]

Hi,

I recently bought an HP OfficeJet Pro 6960. From one day to the other, the printer has stopped working. I believe this is due to an automatic update. The error i see (Blue screen of death) is C9C70000. The printer cannot be used. I cannot access menus, nothing at all.

This is quite disappointing as I just bought the printer for more than a £100 and it is not acceptable that it can break so easily. 

I have tried the following:

- Remove power cable for more than a minute. plug back in the printer. 

- Turn on and off the printer. 

- Leave it overnight. 

- Remove 3 out of 4 cartridges and restart the printer.

Is there any way I can reset the printer to factory settings? This might fix the issue. Who knows. Any other solutions apart from taking it back to the shop? I would like to avoid wasting time.

Thank you for helping.

when you say you unplugged the cord...did you do it while the printer was on?  unplugging the printer while on and waiting a minute before plugging back in performs a hard reset.  Make sure to plug it into a wall outlet and test again.

Yeah. done that. No luck. Exactly the same error.

Printer was working fine last time I used it, now when I turn it on it has the loading screen with the bar for a few seconds and then automatically brings up a bright blue screen with the power symbol and the error code C9C70000. Have tried to unplug the power cord from the printer then from the wall, replugged it all back in after waiting a few minutes. I have removed the ink cartridges even though the bar will not slide over from the right side. I have repeated these steps for the last hour or so and nothing changes.

@SammiB0507,

Thank you for posting your query on HP Community,

Have you checked for any obstructions inside the printer?

As you have mentioned that the bar will not slide over from the right side? Have you tried to move the carriage manually.

This looks like a possible hardware failure with the printer. However, I would suggest you try these steps here: 

Let's start off by updating the printer firmware. If your printer connected wirelessly, make sure to temporary connect the device with USB and then follow the link to install the latest firmware update on your printer from our HP support website. Alternatively you can also try to update the printer firmware directly from the printer control panel.

For more details on how to update, please use this link: HP Printers - Updating or Upgrading Printer Firmware

If the issue persists, I would suggest here is to do a hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

My story with this printer ended at Curry's where they told me this is a known flaw and there is nothing to do about it. I gave the printer back and bought an Epson with Eco-Ink. 

Do not buy this printer if you need a working one! 😄
