PhotoSmart 7510 scan function doesn't work right after updating Maverick

Question

It was an ordeal but hp support was finally able to get my MAC to recognize my PhotoSmart 7510 all-in-one after the operating system was updated to 10.9.5. But now I get the scan function but I have no options as to size, dpi or what type file I want to save the scan to. Also, the quality is TERRIBLE. Granted I'm trying to scan old photographs but I was able to do this with no problem before. Now the grayscale is off and light areas of the images don't scan at all.
I know that all the drivers are up-to-date but I don't know how to fix this problem.
