I appreciate your fast service, but I have a problem with the color cartridge HP#75XL in my HP Photosmart D 5360 printer. The black works fine but on the printer screen, it keeps saying print cartridge incorrectly installed. I have removed them both and re installed many times and erased the contacts with the eraser you supplied with the carridge, but each thing I try to print even on "best" comes out very washed out. I have aligned and cleaned the heads a number of times. What do you recommend?
