Support Code 7800 & Can't Access Ink Cartridges

[pdipaolo]

I get Support Code 7800. I cannot clear the code so I can reset the printer. And I cannot access the ink cartridges to change them. How can I clear the code so the buttons will work for the other functions. Unplugging does not work either. It is locked on the error code message.

Thanks for joining the conversation, pdipaolo!

So that the Community can help you better, we need to know exactly which Canon printer model you're using. That, and any other details you'd like to give will help the Community better understand your issue!

Hello. The only thing I know is that it is a Canon TR4500 Series and suddenly stopped working giving the error code 7800. 

Any advice?

Thank,
