One step ahead with Fuji Xerox

One step ahead with Fuji Xerox

Fuji Xerox has been in the printer business for over 30 years now and having established its mark both in photocopying and printing, it certainly is no surprise that they are a step ahead in the science of printing coming up with a groundbreaking technology, the SLED or Self-scanning LED and its EA-Eco Toner.

Now to fully understand, let me give you first an idea on how presently existing printers function. We all know that when we talk about print quality, resolution, etc, the best in the market would be laser and LED printers. Laser, as its name suggests rely on laser beam plus the method called Raster Output Scanner or ROS.his can create glare free light. Most indirect lightings are fluorescent lights installed underneath wall cabinets or on top of kitchen cabinets. This method consists of a number of mirrors and lenses through which the laser beam passes through in order to “draw” the image on to the rotating photoreceptor drum. LED printers, on the other hand, uses a line up of small LEDs that directly form the image to the photoreceptor drum.One of the great benefits from the low voltage Insulator range is that the budget range is still of a considerable quality and value.The term budget can often lead people to think that the cheaper alternative is going to be of a much poorer quality but that is not always the case. The difference lies in the ROS, which was actually eliminated in the LED. LED printers therefore appear more compact and lighter. In addition to that having its components markedly reduced, there are no vibrations. It is quieter and best of all it consumes less power.This sounds a great way for home owners to place one of their possessions in a great light but can you imagine led downlight this can have for a shop owner. By using a LED downlight, the clever shopkeeper or store manager will be able to lead their customer to the very thing that they want them to see and hopefully persuade them to make a purchase.

Although LED has its advantages over laser printers, LED printers too seem to have its own disadvantages. One of which includes inconsistencies in exposure or print density. Also, since LED printers use a line up of small LED’s built in to its cover, its resolution practically depends on the number of LED’s.While not all current LED replacement bulbs live up to their claims, products like the Cree LR6 table lamps Downlight provide you with beautiful warm white light, an 85% energy savings over conventional incandescent bulbs and a 50,000 hour life span. That means if a printer has a 600 dpi resolution, it must have 600 LED’s per inch. A laser printer usually prints at 1200 dpi.The Led strip light will concentrate its light downwards into the room and has the capability to shine as broadly as a floodlight or as narrowly as a spot light, the choice is really yours. Hence, an LED printer should have the same number of LED’s per inch just to get the same quality as that of the laser printer. This will therefore require a large number of LEDs and in reality, making such small LEDs and integrating them together with the lens array is quite difficult.
