I've never tried it myself but have heard mixed results from other techs. First you will want to measure it out by weight. DV-613 is a much larger volume bag than DV-614. While I'm confident that the steel powder base is the same, the toner mixed in is different. I have heard that it will produce a slightly different hue until it gets fully refreshed with TN-619 toner. I wouldn't calibrate the Fiery until after a thousand impressions or so.
