Remanufacturing the Samsung ML-2850/2851ND
by Mike* Josiah and the Technical Staff · Summit Technologies, a division of Uninet Imaging Inc. · June 1, 2008 - page(s): 23-39
First released in January 2008, the Samsung ML-2850/2851ND printers are based on one of Samsung’s newest engines. The ML-2851 series runs at 30 ppm with a maximum resolution of 1,200 dpi. The first page out is stated to be under 8.5 seconds, and the printer comes standard with 32MB of memory (expandable to 160MB). As the model number implies, duplexing and a network card are built in.
These cartridges do not have a drum cover and come new with a piece of heavy paper taped around the cartridge (see Figure 1). All new cartridges opened so far have shown some toner leakage on the drum that would have shown on any prints for at least a few pages.
The standard cartridge (Samsung part No. ML-2850A) is rated for 2,000 pages. The HY cartridge (Samsung part No. ML-2850B) is rated for 5,000 pages. As with pretty much all cartridges these days, the cartridge has a chip and it has to be replaced each cycle.
Cartridge troubleshooting as well as common error messages will be listed at the end of the instructions.
