How do i reset black? after refiling

Hi there, I have the same printer so this is easy. Once you have fitted the new cartridge, switch the printer on, go into control panel, printers and scanners and then right click on the Canon printer and select properties. Once in properties, click on the maintenance tab and then click on printer alignment and follow the alignment procedure. The printer will detect the new cartridge and then run the alignment procedure. When finished, the printer should be ready for use.
