Genuine OEM Canon PIXMA MX492 Ink and Supplies
The Canon PIXMA MX492 uses one black cartridge and one tri-color cartridge. PG-243 and PG-245 cover the black position, while CL-244 and CL-246 cover color; the XL choices provide more capacity in the same two positions.
Toner Buzz carries genuine Canon black and tri-color ink for each of those cartridge families, including individual cartridges and combined packs. Follow the printer alert for black or color, then match the number printed on the cartridge already in use.
