T642
One step up the T-series ladder, the Lexmark T642 refined the T640 formula with a faster engine for higher-volume departments. Lexmark kept the chassis and controls familiar, so upgrading users faced zero learning curve. Best of all, it shares the proven 640H high-yield cartridge with its predecessor, so existing toner stock carries straight over. Compatible 640H cartridges make this step-up printer even easier to justify.
