I havne't worked with edible images, but I've had that problem before with regular printing. It means you only have the magenta (red) ink left- you are out of yellow and blue. If you replace the cartridge(s) that should fix your problem. Hope this helps!
It looks like you are out of ink. I know that my copier prints in pink when low in ink.
You may
1) have run out of ink
or
2) have clogged cartridges.
Do you have a cleaning cartridge? If not, use a cotton swab and some alcohol to gently clean the cartridges where the ink comes out.
This has happened to me once before, so I just printed the image in b/w...in your case, pink and white, and then I handpainted it with food colorings. I guess if it's a photo of a person you won't be able to do that, but if it's a cartoon you can.
BTW..Lisa is the edible images expert....try pm'ing her....
Try doing a cleaning and then check on regular paper first before you use a edible sheet.
Okay, cleaned it twice (have a cleaning kit) and now the color is a little bit better - still pinkish and it's printing lines across the whole thing! 
I don't know what else to do, I live in a small town and the closest walmart is 1.5 hours from here and the cake has to be delivered by 2:00. I'm trying to print the 6 Disney princesses.
What else to do???? besides cry!
Man Gibson..I wish I could help..This is sorta the reason I haven't purchased one yet..still don't know if I want to deal with these problems!! Hope it works soon!!
Thanks everyone for your help!
I let the printer sit (actually I just sat here wondering what was I going to do!) for a bit after I had cleaned the head and it worked fine. The color magneta is low (all of the pink printing I'm guessing) but all the other inks are full. I still don't understand it but it worked and made me very happy!
Thanks again!
