Perhaps the following is the issue, not sure, not enough info...:
Check print settings. Is printing for color / BW set to auto? If system is misinterpreting, BW will be printed (mixed) from your color cartridges. Force BW manually then your black cartridge is used and you should not get a tint.
Had the same issue with a Canon pro-100. Always make sure that the software you are printing from has printer properties set to grayscale or B&W. Color cast was removed by doing that.
