Enterprise page output expectations
Yields are measured using the ISO/IEC 19798 standard for colour laser devices at 5% page coverage. The TK-859K black cartridge provides up to 25,000 pages, while the TK-859C, TK-859M, and TK-859Y colour cartridges yield up to 18,000 pages each under standard testing conditions.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| TK-859K | Standard | Black | 25,000 | $0.003 |
| TK-859C | Standard | Cyan | 18,000 | $0.012 |
| TK-859M | Standard | Magenta | 18,000 | $0.012 |
| TK-859Y | Standard | Yellow | 18,000 | $0.012 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.
Ordering strategies for commercial printing
Replacing cyan, magenta, and yellow simultaneously prevents uneven toner depletion across high-volume print runs. Check inventory levels for all three colours before initiating large graphics projects. Free delivery applies on all orders over $99 dispatched quickly from warehouses in Perth, Brisbane, Sydney, Melbourne, and Adelaide.

Expert operational recommendation
Keep a spare TK-859K black cartridge on hand; Kyocera TASKalfa engines run automatic calibration cycles that draw minor amounts of toner during daily start-up routines, depleting low cartridges unexpectedly during heavy print jobs.
Frequently Asked Questions
Why does the TK-859 black cartridge yield 25,000 pages while the colour cartridges yield 18,000 pages?
Kyocera designs black cartridges with a larger internal physical chamber to accommodate heavier text-document workloads common in corporate environments, whereas colour toner formulations use different particle densities calibrated for precise image reproduction.
Can I replace an individual TK-859 colour cartridge without replacing the other colours?
Yes, each TK-859 cartridge operates independently in its dedicated slot, allowing you to swap out only the empty colour while continuing to use the remaining cartridges.
How does page coverage affect the stated 25,000-page yield on TK-859 cartridges?
Standard ISO yields assume 5% coverage per page (roughly a short letter). Continuous printing of dense graphics or full-page charts increases toner consumption, proportionally reducing total page output.
