Application of SLED Technology in Printers

The characteristic of LED is that only one LED light point lights up each time the electronic pulse is turned on, and the LED light points move to the front one by one. One signal line operates a row of LEDs to light up, thereby controlling one input. The SLED technology developed by Fuji Xerox is the abbreviation of Self-scanning Light Emitting Device . Each SLED chip has 57 LEDs. One SLED chip is controlled by two signal lines. The 57 SLED chips have 114 signal lines, which can control up to 14,592 light points. Only 114 signal lines are needed to control all SLEDs.

The LED printer uses a straight paper feeding path for one-shot imaging. This paper feeding method can effectively reduce the paper jam rate and can accommodate thicker paper. It can print 268gsm thick paper. In addition, the distance between the LED light head and the photosensitive drum is very small, so the printer size can be very small. The LED head is made entirely of semiconductor components, so the stability and reliability are very good, and the service life is relatively long.

The official name of SLED technology is DELCIS, which is digitally enhanced light-emitting diode image control technology. SLED technology was developed by Fuji Xerox, a Japanese manufacturer. Its fundamental purpose is to reduce the size of printers and all-in-one machines, and to better control the size of products by changing the paper path and imaging method. The development of SLED technology is also to ensure high-quality output of files. SLED technology can achieve a true 1200×2400dpi resolution. It ensures high-quality output of 1200×2400dpi through advanced LED print head technology and higher-level imaging technology. The LED print head technology includes a new design lens , a 1200dpi precision S led chip and a full-featured ASIC controller . The higher-level imaging technology uses image enhancement processing and MAC S hanging network technology.

Compared with traditional LED printing technology, SLED technology can ensure that users can reduce the light interference between two adjacent LEDs, reduce the image stripes of traditional LED printers, reduce the bottom dust of traditional printers, and reduce the LED printer's dots being too large and affecting the print quality.
