Return it as faulty and get a new one. If it's full and new and now reads empty, it means the chip on the cartridge is bad.&nbsp;</P> Tue, 01 Nov 2022 20:28:26 GMT bellevuefineart 2022-11-01T20:28:26Z https://community.usa.canon.com/t5/Professional-Photo-Printers/Ink-Tank-Replacement-error-Prograf-Pro-1000-printer/m-p/391489#M13784 <P>Tell me I didn't make a $75 mistake. I inserted one DGY ink tank cartridge into the Pro-1000 and immediately took it back out to do the shake thing. I put it back in and now it registers as a used tank that needs replacing. Is there a way to reset the printer to recognize this tank as new? Or do I have to go buy another one to make it read as new?</P><P>Thanks, won't make that mistake again.</P><P>Patrick</P> Thu, 27 Oct 2022 20:52:36 GMT https://community.usa.canon.com/t5/Professional-Photo-Printers/Ink-Tank-Replacement-error-Prograf-Pro-1000-printer/m-p/391489#M13784 patrick-seattle 2022-10-27T20:52:36Z https://community.usa.canon.com/t5/Professional-Photo-Printers/Ink-Tank-Replacement-error-Prograf-Pro-1000-printer/m-p/392141#M13801 <P>That sounds like the chip is damaged.
