Canon PIXMA iP4600 Ink Cartridges
Your Canon PIXMA iP4600 uses the PGI-520 and CLI-521 ink cartridges, a five-ink system engineered for crisp text documents and detailed photo output. Ink Depot has been supplying reliable consumables for this printer since Aug 2026. Replacing the PGI-520BK pigment black keeps everyday documents sharp, while individual CLI-521 dye tanks allow targeted colour replacement as specific shades deplete. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected Output and Ink Consumption
Page yields for PGI-520 and CLI-521 cartridges are measured using ISO/IEC 24711 standard test patterns. Because photo printing uses full-bleed ink coverage, actual CLI-521 page output varies based on image density, whereas PGI-520 pigment black offers consistent yields for text documents.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| CLI-521BK | Standard | Black | 1,875 | $0.012 |
| PGI-520BK | Standard | Black | 350 | $0.067 |
| CLI-521C | Standard | Cyan | 505 | $0.046 |
| CLI-521M | Standard | Magenta | 471 | $0.049 |
| CLI-521Y | Standard | Yellow | 505 | $0.046 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.

Pro Tip for Five-Ink Cartridge Systems
Always verify whether your print job uses pigment black (PGI-520BK) or dye black (CLI-521BK) before ordering single replacements. The PGI-520BK operates on plain paper text documents, while the CLI-521BK is specifically formulated to enrich shadow detail and contrast on glossy photo paper.
Frequently Asked Questions
Why does the Canon PIXMA iP4600 use two different black cartridges?
The PGI-520BK contains pigment black ink designed to bind to plain paper fibres for sharp text printing. The CLI-521BK uses dye-based black ink, which blends smoothly with Cyan, Magenta, and Yellow dye inks on photo media for enhanced shadow detail.
Can I continue printing if one CLI-521 colour cartridge is empty?
No, Canon PIXMA printers require all five cartridge slots to contain usable ink and functional microchips. Operating the printer with an empty slot risks overheating and damaging the thermal printhead nozzles.
How do CLI-521 dye inks handle uneven depletion during photo printing?
Because image colour palettes vary, individual dye cartridges deplete at different rates. Replacing individual CLI-521 tanks as they run out avoids wasting unused ink in remaining colour slots.
