Canon PIXMA MX436 Ink Cartridges
Your Canon PIXMA MX436 uses the PG-640 / CL-641 series ink cartridges, operating a dual-cartridge system where one cartridge holds pigment black ink and the other houses a combined tri-colour unit. We have been supplying replacement consumables for this printer since Apr 2013. Replacing a combined tri-colour cartridge means you get a fresh printhead built into the unit each time, preventing stubborn nozzle blockages during lighter home office printing. Our 4.8 Google rating is built on dependable cartridge performance and uncompromising product quality.
Expected Page Output and Replacement Cycles
Page yields for the PG-640 and CL-641 series are calculated using ISO/IEC 24711 testing standards, which measure continuous printing on standard A4 plain paper at 5% coverage. Standard capacity units output 180 pages, whereas the high-yield XL options deliver up to 400 pages and the PG-640XXL black cartridge reaches approximately 600 pages.

|---|---|---|---|---|
| PG-640 | Standard | Black | 180 | $0.14 |
| CL-641 | Standard | Colour | 180 | $0.19 |

Pro Tip
Because the CL-641 tri-colour cartridge contains cyan, magenta, and yellow ink in three separate internal chambers, running out of just one colour will prompt the printer to report an empty cartridge—printing mostly text with occasional dark borders helps balance the three colours evenly.
Frequently Asked Questions
Can I install a PG-640XXL cartridge if my printer currently has a standard PG-640?
Yes, the PG-640XXL has the exact same external dimensions as the standard PG-640 and PG-640XL cartridges; it simply holds a higher volume of ink inside the casing and fits directly into the black cartridge slot.
Why does the tri-colour cartridge need replacement when two of the colours still show ink?
The CL-641 series uses a single housing with individual chambers for cyan, magenta, and yellow. Once any single chamber depletes, the printer flags the unit as depleted to prevent thermal damage to the integrated printhead nozzles caused by firing dry chambers.
Will using the PG-640XXL black cartridge require a different installation process than standard cartridges?
No, the installation is identical across standard, XL, and XXL sizes. You snap open the carriage lever, slide the cartridge in at an angle until it clicks securely into place, and close the retaining latch.
