Canon PIXMA MX850 Ink Cartridges
Shop ink cartridges for your Canon PIXMA MX850, which uses the Canon PGI-5 and CLI-8 ink cartridge series. Ink Depot has been supplying reliable consumables for this printer since Aug 2026. Designed as a feature-rich office all-in-one with duplex printing and an automatic document feeder, it relies on high-capacity pigment PGI-5BK tanks for crisp text documents while CLI-8 colour tanks handle graphics. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected page output and replacement cycles
Yield measurements follow ISO/IEC testing standards for inkjet cartridges. In daily home office printing, high-capacity PGI-5BK pigment black cartridges deliver substantially higher page output than CLI-8 colour tanks, as text-heavy document workflows deplete black ink first.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| CLI-8BK | Standard | Black | 65 | $0.46 |
| CLI-8C | Standard | Cyan | 62 | $0.49 |
| CLI-8M | Standard | Magenta | 53 | $0.57 |
| CLI-8Y | Standard | Yellow | 40 | $0.34 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Choosing between genuine and compatible options
Opting for compatible PGI-5 and CLI-8 ink cartridges offers substantial savings without compromising document legibility or colour output. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. For a detailed breakdown of performance, read our guide on genuine vs compatible cartridges.
Best way to stock these cartridges
For general text printing, purchasing PGI-5BK black cartridges individually or in value bundle packs ensures your office stays stocked at the lowest cost per page. If you produce full-colour flyers or photos, buying complete CLI-8 multipacks prevents uneven cartridge exhaustion. Compatible cartridges include a money-back guarantee for complete peace of mind.

Key Purchasing Tip
Always distinguish between PGI-5BK pigment black and CLI-8BK photo black cartridges when reordering; PGI-5BK handles sharp plain-paper text documents, whereas CLI-8BK is specifically formulated for contrast and shading in photo printing on glossy media.
Frequently Asked Questions
Can I mix genuine Canon PGI-5 black cartridges with compatible CLI-8 colour cartridges?
Yes, your Canon PIXMA MX850 allows individual cartridge replacement, meaning you can run genuine PGI-5BK pigment black alongside compatible CLI-8 colour tanks without causing system errors or print defects.
Why does my PIXMA MX850 require two different black cartridges?
The printer uses PGI-5BK pigment ink for crisp, smudge-resistant text on plain paper, while CLI-8BK photo black ink is used for smooth tonal gradations when printing photos on glossy paper.
What should I do if my CLI-8 colour cartridges exhaust at different rates?
Because colour document coverage varies, individual CLI-8 tanks deplete unevenly. Replacing individual colour cartridges as needed or keeping a full CLI-8 multipack on hand ensures uninterrupted printing.
