I am having some of the same issues as Paul and have yet to produce a satisfactory print on my 7890. I have the selenium set and all I am getting are pink prints! Is anyone (administrator or user) willing to converse by phone when I am in front of my printer? My internet connection is in a different room than my printer and it is very difficult to tackle problems via online conversation. I too have downloaded what seems to be everything, but I have obvious problems. I have also inexplicably gone through almost all of my selenium tone ink (slot #9 on 7890) while only producing a dozen or so prints. The printer was new and I overcame a different problem (printer not recognizing cartridge) recently, but now there is this problem.
Thank you for any assistance.
