https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/PGBK-not-just-for-documents/m-p/262972#M4121 <P>Everything I have read has lead me to believe&nbsp;that the PGBK is used just for document. I have since found out that, that is not exactly true at least for some printers. I have an ix6820 that the for some reason the PGBK cartridge&nbsp;stopped working. But, I could still print great glossy pictures on it just fine. I could not print black and white documents, which was fine because&nbsp;I had the other printer that I could use. After a while I started having&nbsp;other issues with the ix6820 so I decided to get a new printer. I wanted one that used the same ink cartridges so I got an ip7220. When I got the new printer I just moved the cartridges&nbsp;from the old printer to the new printer.</P><P>Long story short the photos from the ip7220 where terrible. I tried everything I could think of the correct the color imbalance, but nothing worked. Then I thought to try one more thing. I figured the since the PGBK has been sitting in the ix6820 for years without being used that it was probably all dried out. So I replace that cartridge with the one that came with the new printer and lo and behold the photos came out great. So I have to conclude that the PGBK does effect the color on at least high quality glossy photos.</P> Sun, 30 Dec 2018 15:30:42 GMT rickb2030 2018-12-30T15:30:42Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/PGBK-not-just-for-documents/m-p/262972#M4121 <P>Everything I have read has lead me to believe&nbsp;that the PGBK is used just for document.
