After installing all the cartridges my printer gave an error that the Cyan cartridge was "missing." I reinstalled the old Cyan and it was fine. I reinstalled the new Cyan same problem. After 7 times of swapping back and forth and cleaning the contacts with alcohol the printer finally recognized the new cartridge. Then I printed eight 8x10 color photos and the 3 color cartridges showed only 1/3 ink remaining. I know that the color cartridges are only "Standard Yield " but come on! And 4 of the photos printed had red blotches in the top left of the photo. I will have to run a printer alignment test to confirm that was not the issue.
