Just found today that Gray and Photo Magenta are running low. From the ink details page, those 2 are less than 10% while all others are about 80%. Any idea what's the cause? Thanks.</P> Thu, 08 Apr 2021 03:44:09 GMT https://community.usa.canon.com/t5/Professional-Photo-Printers/some-pro-100-ink-cartridges-run-out-much-faster/m-p/339462#M11417 ccu336 2021-04-08T03:44:09Z https://community.usa.canon.com/t5/Professional-Photo-Printers/some-pro-100-ink-cartridges-run-out-much-faster/m-p/339474#M11418 <P>The photo inks - cyan and magenta - are used fastest with my Pro-100&nbsp; It all depends on what you are printing.&nbsp;</P><P>&nbsp;</P><P>I used to have a Pro-9000 that had red and green inks instead of the two grays of the Pro-100.&nbsp; The red and green&nbsp; seemed to last forever.</P> Thu, 08 Apr 2021 11:00:54 GMT https://community.usa.canon.com/t5/Professional-Photo-Printers/some-pro-100-ink-cartridges-run-out-much-faster/m-p/339474#M11418 jrhoffman75 2021-04-08T11:00:54Z
