Am using the Eb6 inkset in my 1400 and scanning some old family b/w photos. Until recently, until the last 3 or 4 prints, the blacks were deep and rich. Now they're a bit faded and weak. And using Red River Aurora Natural with this profile that came with QTR: Eb6-RedRivAurora-11-2011. quad For some reason I can't find its parent .QIDF file in my Profiles folder. I'll keep looking or maybe some kind soul would sent it to me - then it could be tweaked if need be. I would definitely need help with that.
Recently filled all the carts (I mix my own, so it's really the Cb6 inkset) and nozzle checks are perfect.
