I have a canon pixma mp130 and I am having trouble with the ink. It was working just fine before I brought it to school and now it won't work for me. The problem is that it will not print black the most important color needed. I tried to do the cleaning and the deep cleaning but it still won't work. I put in a new cartridge just in case that one was bad but it still won't work. I tried wiping off the end but that did nothing. Does anyone have any other suggestions? Thanks
