Canon 0459B003 GPR-23 Yellow Drum Unit toner cartridges (genuine brands)

Yellow Drum Unit for imageRUNNER series

This genuine Canon drum unit carries part number 0459B003 and the GPR-23 designation. It is built for offices that run compatible imageRUNNER models and need reliable yellow imaging. The component installs directly into the designated drum slot without modification. Buyers who need a different colour drum or a combined toner-and-drum cartridge cannot use this unit.

60000-page yield at 5% coverage

Rated output reaches 60000 pages when measured at the industry-standard 5% coverage benchmark. That headroom supports high-volume colour workflows across models such as the C2550, C2880, C3080, C3380 and C3480 families. Heavy graphics or solid-colour pages will reduce the practical page count well below the rated figure.

Drum life limited by mechanical wear

The imaging drum surface and drive gears set the practical service limit; once the rated yield is passed, print quality degrades and the unit must be replaced. No separate toner reservoir is included, so a matching yellow toner cartridge is required for complete operation. Compatibility is restricted to the listed Canon imageRUNNER devices.
