Canon Pixma G3010 comes with pigment-based black ink and so, dye-based black ink cannot be used on it. The printheads are designed for use with specific inks. If you use other inks (not recommended for use in your printer), the printheads get damaged, resulting in poor print quality. Also, the printer’s warranty will also be affected. Avoid refilling the ink cartridges on your own and do not purchase cartridges from local vendors.
