Many elements may cause the Canon printer to print blank pages, such as print settings, low ink, or the product itself. But in some reports, users ask why is my Canon Printer not printing black when the ink is full. So, to troubleshoot this issue, try to print a nozzle check pattern to check if any of the nozzles are clogged. Then, if necessary, clean the print head. Also, check that your printer software's paper size, orientation, and layout settings are correct, ensure that your Canon printer is placed on a flat, stable surface, and you are using supported paper. Further, check that the document you are printing doesn't have blank pages.
