PIXMA TR4500 Series: 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.

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,

Paula
