I inserted a new 160ml cartridge and I could hear it dripping into the main tank.</P><P>It displayed full and I made 2 11x17 inch prints.</P><P>I turned the printer back on the next day and the cartridge displays as empty!</P><P>What happened to the 160ml of new ink? Is it leaking somewhere into the botton or back of the printer?</P><P>I don't need a flood of black ink on the beige carpet that is under the printer.</P><P>How do I get support from Canon Professional Printers Support?</P><P>Some things are NOT easy to find on the website.</P> Fri, 18 Oct 2024 13:15:11 GMT https://community.usa.canon.com/t5/Production-Printing/imagePROGRAF-PRO-4000-When-I-insert-a-new-MBK-cartridge-it/m-p/506953#M2005 Rodagon80 2024-10-18T13:15:11Z https://community.usa.canon.com/t5/Production-Printing/imagePROGRAF-PRO-4000-When-I-insert-a-new-MBK-cartridge-it/m-p/507704#M2013 <P>We had the same issue.
