Xeikon Unveils New Generation Dry Toner Technology


The next generation Xeikon SX30000 press is an entirely new, robust single pass duplex machine, powered by the new SIRIUS technology, and can run at a printing width of 508mm on a broad range of substrates at 30 metres/minute or 404ppm A4. It boasts an average speed increase of more than 50% throughout the range of 40-350gsm versus the previous platform.

The first digital press based on this new technology will be launched and commercially available as of June 2020. Xeikon has been allocating major resources since 2017 to set a new standard in dry toner technology and develop a new platform for the graphic arts industry. ‘The water cooled LDAs, with 1200 x 3600dpi technology and the single pass duplex, full rotary concept, have remained unchanged, as well as the 5/5 print station setup. Almost everything else has been re-engineered,’ said Dimitri Van Gaever of Xeikon. ‘One of the things that really sets the SIRIUS technology apart is its ability to print on heavy substrates at high speeds.

Van Gaever explained some of the core components that enable SIRIUS to set a new standard: ‘We have been working along 4 major axes: toner development, imaging technology, fusing technology and media conditioning, resulting in more than 400 design changes and developments compared to the previous generation. All these core components have been redesigned and enhanced to deliver superior quality, market leading performance, unequalled sustainability, the widest application range and best-in-class TCO.

An important step to bring SIRIUS technology to a new era of productivity is realised thanks to Xeikon’s new EkoFuse technology: a new fuser and a patented new crossflow cooling system add up to achieve superior print quality levels at market leading speeds.

For our newly developed SIRIUS toner, we have changed the production parameters of the toner and have improved the charging kinetics properties by adapting the outer shell of the toner to cope with the higher engine speed. Our new developer unit ensures superior image quality for high coverage applications.’

With the SX30000, Xeikon is first and foremost aiming at high value applications, usually featuring high coverage colour content on high-quality papers combined with superior quality requirements. ‘This can be in the book printing segment or high-quality direct mail, but because of the versatility of the technology, it might also be in retail and signage materials, security printing and other general commercial print. Furthermore, we are looking at customers who need higher productivity combined with lower running cost and a compelling overall TCO.’

‘We have been the pioneers of dry toner technology, and we continue to see opportunities to further enhance it and improve on it,’ said Van Gaever. ‘The technology has been named SIRIUS – after the brightest star in the night sky and in reference to its role in helping people to navigate and set course in various cultures throughout history. We believe this platform will lead the way towards a profitable business for our existing and future customers.’
