I have mf 595 and mf 590, both boxed. Perhaps some people won't like what i have to tell but the box of the mf 590 is slightly different from the mf 595 box. Both boxes seem similar, but on the back of the mf 590 there is a factory printing change over the description of the mf 595. You can see the description of the mf 595 through it. The change refers to the caracteristics of the mf 590. So all those who think their problems are solved by putting a mf 590 in an mf 595 box are just fooling themselves. Would like to post pictures... but just don't know how!
