Hello my name is***** do not rate until we are finished. I look forward to assisting and am very sorry to hear that you are having this problem. I want to warn you that it is possible you will need to replace a part in order to fix this. There are a few different things that can cause this and a couple different parts so we would need to troubleshoot to find out for sure. I do not see any previous questions are you sure this is the correct site? This is a paid tech support site called JustAnswer.com. Why do you think it is not possible for the black to be empty? There is no bypass option.
