I have replaced both ink cartridges, calibrated, removed and replace the printer heads and it acts like it is printing but the sheet is blank. Also, the color won't switch to black & white or from black & white to color, uses up all of the yellow and then requires that the cart. be replaced, quality is horrible. This printer is a piece of junk - nothing be problems. After reading through all of the problems here, most are just what I am having. I will not buy any more Kodak printers - JUNK!
