Red Will Not Print V305W

I have a V305 wireless all in one printer. A while ago it stopped printing red. I just assumed it was the ink cartridge and bought replacements at Office Max. When I installed the new cartridges, I got the same problem. Black, blue and yellow will print fine but no red. I thought that it may be a problem with the non-Dell cartridges since they are never able to show the ink levels. So I went to the Dell website and purchased the Dell brand ink cartridges ($98!). I installed them and I still have the issue. Everything is aligned properly and everything else prints fine. Just no red.
