Hi!
I know this thread was opened a while ago. I hope someone will see this.
I have the same problem; magenta/pink background on all pages.
Here are a few precision:
-When I used the Engine test print, no magenta background.
I can see black, yellow blue and magenta lines all over the page.
If I print a word file with only text: no magenta background.
If I add a graph with color to the word document: Magenta background appears
If I ask for grey scale printing: No magenta background.
If I print a status sheet from the printers menu (not from the PC) the magenta background is there!
