I have an 8750 printer. It worked great for a while. Printed quite a number of glossy 11x17's from photoshop no problem for a big office presentation. Didn't use the printer for a few months, then when I went to use the printer, the colors started having real problems, giving a posterized look. So first I bought new cartriges, no improvement.
I went throught the cleaning and testing cycles. Now it is not completely posterized any more but the highlights are completely blowing out and turning white and orange. But only on photo paper, on regular plain paper the prints are perfect. It seems to me that this is a software or firmware problem. I have downloaded and installed the latest drivers.
Tried and tried, using small images, selecting different paper, resolution, color controlled by.. options and using many brands and types of photo paper. One time it came out perfect on a small 2x3 test, thought it was fixed, went and printed same image, same settings from photoshop full size and the blown out highlights came right back. Printed on plain paper and again print was perfect. Tried every setting imaginable, including the full DPI but no difference. Also tried printing straight from Windows default picture viewer, same problem. Also put a 500mb flash card into the slot (for printer RAM?)
Ran cleaning after cleaning and test after test. The test page comes out showing good, but randomly sections of the fine color strips at the top are completely missing, using the print test protocol from the printer's control panel. Any ideas are really appreciated. Otherwise this is an expensive piece of ewaste. Help me solve this problem or the printer gets it!!

comparison of images on plain paper versus glossy paper can be seen here, I cannot figure out how to imbed image in post
Also, the image prints fine from my Canon color printer on 8.5 x 11 which is the size I was trying to print from the 8750. Finally, I also tried printing jpg version of the image from a CFcard plugged into the printer, same result. Bad. Weird how it is selecting the areas to blow out.
