In October 2007 Samsung introduced the ML-1630, ML-1631, SCX-4500 MFP and SCX-4501 MFP. Print speeds were OEM rated at up to 17 letter-sized pages per minute (ppm) with duty cycles for all models rated at 5,000 pages per month.
The supplies set is made up of a single all-in-one toner cartridge that requires a chip for the printers to function correctly.
