Xerox swaps laser for LEDS in new multifunction printers

14-City India launch for WorkCentre 7400 series

Xerox – the people who invented the dry copier and  saw their name define  the process , would like the world to  forget this piece of technology history and think of them as an innovative document management company. Last week they unveiled yet another new technology in what was hitherto an exclusively laser- driven printer portfolio and brought   LED-based colour multifunction printers to India.

Replacing the laser in laser printers with an array of light emitting diodes or LEDS is not exactly a recent  development. The technique was first used  in 1991 by the Japanese printer player OKI Data and TVS brought it to India in the form of a monochrome printer with laser-like quality. Today’s LED technology is a far cry from these early efforts ( which never took off commercially) and the new 7400 series WorkCentre printers announced by Xerox have outstripped the best resolution possible with lasers to offer a 1200 by 2400 pixel quality. This means the A3 width carriage has over 15,000 LEDS doing the work of a scanning laser – with no moving parts and at vastly reduced power. Xerox has partnered with Nippon Glass for the “HiQ”  chip that ensujres uniform LED  intensity and joins Fuji in launching this new Second Coming of LED printer technology.

Princy Bhatnagar, Xerox India’s Director Office Business Group, says the environment friendly and power efficient features of LED technology are the main reason why they are gaining prominence – and Xerox is the first to offer them in India. The three models – WorkCentre 7425, 7428 and 7435 -- are 11- 20 pages-per-minute, A3 sized print-copy-fax-scan machines with  5000 plus sheet paper capacity, significantly low noise levels, and  the biomass plastic  material produces  16 percent lower CO2 emissions during manufacture than normal plastic. They are being launched across 14 cities this month and   they price ranges from Rs 4 lakhs to Rs 6 lakhs.

Software enhancements include a 2 watt sleep mode, as global printer driver with Mobile Express “pull sourcing” to access a Xerox printer from a mobile phone .
