Oasis Offers Toner, Drum Combination for Lexmark T640 Series
NASHUA, N.H. — Oasis Imaging has released a combination toner and drum for use in the Lexmark T640 series.
The Oasis Lexmark toner and Fuji drum combination performs well in the Lexmark T640, T642, and T644 cartridges. These products can also be used in the IBM InfoPrint 1500 series of printers. The only thing that will change is the chip, which will be dedicated to each manufacturer’s series of printers.
Oasis waited until a combination of drum and toner could be qualified that actually exceeds the OEM output in quality and consistency. Oasis decided that quality was more important than just getting something on the market.
The new Oasis Lexmark T640 toner (650g) and Fuji Optima T640 drum provide a black image density of 1.45 for the entire length of the cartridge cycle.
While a number of other products that were tested have an initial quality level that would be acceptable, the black image density dropped off significantly halfway through a cycle.
