World Leading Technology Innovations
OKI has a long list of pioneering industry firsts developed through the power of its innovation over the last 30 years.
From the first LED printers of 1989, the company has constantly broken new ground, introducing the world’s first A4 colour multifunction printer in 2005 and the world’s first digital LED white toner printers in 2012.
A year later, we set another industry benchmark, with the unveiling of the C941 – the world's first digital LED 5 colour A3 printer.
In A4 digital colour printing, OKI's breakthrough printer innovation has removed the last barrier to creativity and design - how to print in any colour desired including white, simply and cost-effectively.
And at the heart of our innovations is OKI’s pioneering approach with LED technology.
What is LED
LED, or light-emitting diode, is a type of semiconductor element that gives off light and has been used in OKI printers over the last three decades.
Yet it seems that it is only now being ‘discovered’ by a number of leading-edge industries such as automotive, laptop and contemporary lighting design and manufacture.
For manufacturers in these sectors, LED has now been rightly recognised as a highly innovative technology offering them and their customers enhanced performance in such areas as cost-control, quality and environmental impact.
OKI launched its first-generation digital LED-based printers as long ago as 1989 and has continued to refine and improve the technology ever since making it the constant frontrunner in LED technology development.
What Benefits does LED Offer?
In addition to the performance gains offered by LED technology, there is no doubt that its establishment as a credible, mainstream alternative to laser-based print technologies, is due to its ability to meet the unprecedented demand for solutions which can deliver proven return on investment in tough economic times.
This is especially evident in the small to medium business (SMB) marketplace, in which companies are looking to compete with larger competitors with bigger budgets in ever-more aggressive markets.
LED printers are characterised by offering high-speed, high image-quality printing in a simple structure which is simply not possible with laser printers.
Laser printers have a single laser beam as a light source that is divided by mirrors to send light to the image drum, so the internal structure is complex and the actual printer body is often large as well.
Compared to this, LED printers send light directly to the image drum, so they can be designed without mirrors and offer a shorter distance to the image drum, which reduces the size of the printer body.
In addition, the simple internal structure in turn simplifies maintenance.

Structure of LED Print Heads
LED print heads have multiple LEDs arranged in a straight line, and they turn on and off depending on the print signal.
OKI has developed a device (epifilm LED array) that integrates the LEDs with the IC that drives them using epifilm bonding (EFB) technology, and this is used in our LED print heads.
OKI’s LED print heads are made up of a chip-on-board (COB) that mounts multiple epifilm LED arrays on a circuit board for the print width, whether A4, A3, etc., and a rod lens array that produces images on the image drum from the light emitted by the LEDs.
For example, a 600 dpi (dot per inch) A4-size print head has 4,992 dot LEDs arranged in a straight line that each emit light and turn off, depending on the print data, to write the latent image on the image drum.
