Choosing Between Genuine and Compatible Cartridges
Our compatible PG-640XL and CL-641XL cartridges offer a cost-effective alternative to original Canon ink without compromising print clarity for daily documents. Compare genuine vs compatible cartridges to determine the best choice for your budget. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty.
Selecting the Best Cartridge Setup
If you print mostly text documents, choosing the high-capacity PG-640XXL black cartridge keeps cost per page low. For mixed colour printing and photos, combined bundle packs provide both black and tri-colour cartridges together. All compatible cartridges are backed by a money-back guarantee if they do not perform to your expectations. Review our returns policy for total confidence. We despatch all Canon ink cartridges quickly from warehouses in Perth, Brisbane, Sydney, Melbourne and Adelaide. Free delivery applies on all orders over $99.
Cartridge Selection Tip
Because the CL-641 is a single tri-colour cartridge containing cyan, magenta, and yellow ink, running out of any one colour requires replacing the entire tri-colour unit. If your documents use heavy colour branding, stocking an extra CL-641XL cartridge prevents unexpected pauses when one colour chamber depletes before the others.
Frequently Asked Questions
What is the difference between PG-640, PG-640XL, and PG-640XXL cartridges?
All three cartridge sizes have identical physical dimensions and fit into the exact same black ink slot on the PIXMA MX456. The difference lies entirely in internal ink capacity-PG-640 holds 180 pages worth of ink, PG-640XL holds 400 pages, and PG-640XXL holds 600 pages.
Can I install a PG-640XL black cartridge alongside a standard CL-641 colour cartridge?
Yes, standard, XL, and XXL sizes in this series are fully interchangeable. You can mix standard capacity with high-yield cartridges in the MX456 based on whether you print more black text or colour documents.
Why does the PIXMA MX456 use integrated printhead cartridges?
The PG-640 and CL-641 series use Canon FINE technology where the printhead nozzle array is built directly into the bottom of each cartridge. Replacing the cartridge installs a fresh printhead mechanism, ensuring consistent drop placement and preventing permanent printhead clogging in the printer.
