The genuine Samsung CLT-R406 imaging unit, part SU403A, suits the CLP-365W, CLX-3305FN, SL-C410W and C430W colour printers. This unit lasts longer than the toner cartridges, but once it reaches end of life you may see streaks, smudges or an imaging unit warning. Replacing it brings colour output back to a clean finish. It is a worthwhile part to have on hand once your printer starts reporting low imaging unit life.

Storage and handling
Keep the new part in its packaging until you fit it, and store it flat in a cool, dry place away from direct sunlight. Avoid touching surfaces such as the drum or belt, because fingerprints and scratches can mark your prints.
