Cyan in its own cartridge, so only the empty colour is replaced
A colour printer keeps each toner in a separate cartridge, so cyan is replaced when it runs out while the other colours stay in place. The manufacturer rates the magenta and yellow cartridges of the TN-423 series at 4000 pages as well, which makes planning replacements simpler. Yield is a calculated figure: colour-heavy presentations and charts use cyan faster than text with occasional colour elements.
