Dell 5100cn printing problem

[lionsl2005]

Hi Guys, our Dell 5100cn started goving trouble. When a page is printed the content is printed on the paper however the page is covered with blue all across the page over the content. (You can still see the content through this overlaid color.) It is as though extra toner is constantly being printed onto the pages. My guess is that one of the parts needs replacement although it stated to replace the imaging drum, which i replaced. The printer doesn't display any error messages. Could it be the toner is bad? i changed a new cyan as well. but no luck. Any thoughts on what the problem / solution would be greatly appreciated
