To get the issue of the Canon printer not printing black, first, put the paper on the tray. Then, turn on your printer. After the printer is on, check the cartridge door. Next, hold down the cartridge and then remove it. Remove the new cartridge and then remove the plastic tape. Hold the cartridge near the nozzles and then insert it into the ink nozzles. Insert the cartridge into the slot and close the cartridge. See if the problem is fixed.
