CorelDRAW Graphics Suite X6 Test print prints all colors and black OK but files do nor print magenta.

Test print prints all colors and black OK but files do nor print magenta.

Brother inkjet printer MFC-J4510DW, CorelDraw X5, Windows 7

Brother test print does print cyan yellow magenta and black fine. All new cartridges. But CorelDraw 5x files print R:255 G:0 B:0 (#FF0000) as a brown. Did a screen capture of the logo (R:255 G:0 B:0) in CorelDraw and pasted into WordPad and it also printed brown. Why can't I print red if the test print does print magenta?

Thanks for any help!
