"Epson's new AcuLaser C2600 series is unique in that it allows you to switch between mono or colour printing by simply changing the colour toner cartridges. Part of Epson's key strategy to increase its market share in the business workspace, the AcuLaser C2600 series is relatively fast too, offering print speeds of up to 30ppm in mono and 7.5ppm in colour. Shipping as standard with a 350MHz processor and 64MB RAM (512MB maximum), the printer also has a relatively large paper capacity of 650 sheets as standard (expandable up to 1150 sheets), backlit LCD, and Hi-Speed USB, parallel and network connectivity as standard. The major benefit of the 'convertible' design is that it allows organisations to purchase a monochrome printer that can be used to print colour as and when needed. The design also allows black-and-white prints to continue processing even when a colour toner is empty. If you don't need colour, the AcuLaser 2600 N (£379 ex. VAT) is a new monochrome-only model." Maybe I'm missing something here but our Lexmark color laser at work has separate black and color toner cartridges and we have had it for well over a year. If I recall, it still keeps printing black, even if a color runs out. Is this just new to Epson?
