I am printing through Indesign CC 2014, Mac OSX Yosemite, Imac2010. I have updated all EFI drivers and software (3-12-2015) The Konica printer c452 with Fiery controller has been color calibrated (3-12-2015)

The problem I am printing a set of prints and receiving different color results even though the color settings have not been color changed. Settings are SWOP thoughout the ADOBE workflow. Indesign is set to let printer determine color, likewise with EFI printer setting. However what printed as color correct at one instance, now does not. I am unable to get the settings to hold. I am really at a loss for why this continually occurs. Has this happened to anybody else? Any suggestions? I am burning though a lot of paper and toner and still not close.
