The MLT-D308 cartridges are used in Samsung ML-4055 and 4555 printers, which were introduced in January 2010. Both have an OEM-rated print speed of 38 A4-size pages per minute (ppm), and have duty cycles of 200,000 pages per month.
Printers utilizing the MLT-D308 cartridges will not print properly without a new chip on remanufactured toner cartridges. These cartridges are yield and region-specific, making it necessary to match the proper chip to the right cartridge SKU. Please refer to the Chip Center to choose the proper chip for your cartridge SKU.
