Color Quality: Of the five cartridges of my Canon 4850 the three color cartridges (magenta / red, cyan / blue, yellow / yellow) were almost empty. I then the device test printout made with my color printer with color stripes, before replacing the ink cartridges (with original cartridges / -tinte) and after replacing the replacement cartridges. I could not see any color difference. Two other persons to whom I showed the two printouts could not detect any difference. Therefore recommended.
Replacement cartridge with Chip After inserting the Canon 4850 cartridges were detected immediately and the respective cartridges pilot light lit up permanently.
