3 released on 10 new HPIndigo7000 digital printing business using a different method of photoconductor charge for the photoconductor charge is to create a critical step in the printed image.
Hewlett-Packard Laboratories and Hewlett-Packard Imaging Printing Group (IPG) to join hands for a higher printing speed HPIndigo6000 and 7000 series digital presses based on the development of the charge roller charge of the new technology. Charge roller charging technology is commonly used desktop laser printers, and now, HPIndigo7000 digital printing will be a charge to use the technology, the first digital printing products. And other large volume digital printing presses, before HPIndigo products are those which are used in coronary and a voltage wire mesh tube corona, the charge will be imposed on the photoconductor to the surface, and the new charge to replace a roll Corona tube.
this new technology can bring significant benefits the following:
to achieve stability in the line of charge, the processing speed to reach 2.15 m / s, HPIndigopress5500 higher than 76%. In contrast, so far offset any electronic photo-quality printing press to deal with the maximum speed of only 1.22 m / sec.
only charge a roll, even with the installation of accessories, HPIndigopress5500 than in the much smaller tube Corona 3.
charge roller components of the manufacturing costs are significantly lower than the number of corona tube.
to improve the printing cost per page.
reduced maintenance costs and improved ease of use.
reduce ozone production, thereby reducing the ozone filter requirements.
roller charging more than the original design life goals, life can achieve more than 500,000 Indian, other than charging roll life. The high-speed roller
charge by charging technology is located in Palo Alto, California City (PaloAlto) Hewlett-Packard’s central research and development laboratory first. In the course of the study, researchers at HP Labs has made a number of significant progress. The improved version of its research and development charge roller conductive material to provide uniform and reliable high-speed printing requirements of the highly charged. Charging through the roller radial balance of current flow to achieve a longer service life. In addition, in order to be able to guide light on the dark areas of the joints in the right charge, in order to Roll rechargeable maintain clean, so as to ensure a higher image quality, they also created the mechanical and electrical system of compensation. At present, these inventions have been patented inventions.
Hewlett-Packard Laboratories in charge of the successful roll charging on the basis of technical studies, HP Imaging Printing Group R & D team will be charging roller design to product configuration, and through significant improvements in its new printing press at digital HPIndigo7000. In the March 10 release of the other sections of the HPIndigo6000 and 7000 series printer (HPIndigoWS6000 including digital printing and digital printing HPIndigoW7200) also used the charge roller to ensure that the printing speed and industry-leading image quality, labeling and packaging industry Applications, printing speed can reach 100 ft / min (30 m / min), and in the commercial printing applications, printing speed can reach 240 / minute (A44 / 0).
