Rispondi a "excessive reddish in color pictures"if you have changed the brand of your paper or ink, you will have to colour calibrate a new colour profile for the paper and/or ink. if you are using photoshop or similar program select photoshop or other editing program to handle printing not the printer. in print settings-advanced-select ICM and then tick off (no color adjustment). i always work in proof mode in photoshop, selecting blackpoint compensation, simulate paper colour, simulate black ink, and relative colorimetric as rendering intent. if none of these work perhaps do a number of print head cleans (which uses a lot of ink).
