[. . . ] E •   rror diffusion ensures solid fills, faithfully reproduced lines and perfect halftones, and reproduces screened originals without disturbing moiré patterns These capabilities make Océ Image Logic the leading technology for productive ‘green button’ copying and scanning. Every document is scanned perfectly every time, ensuring high-quality copying and reliable archiving with maximum information retention. Handling special originals The Océ TDS800’s 400x400 dpi scanner allows direct selection of different original types: L •   ines and text: default mode for technical documents   hoto: optimal grey scale translation and reproduction • P G •   reys and lines: fine information is retained while area fills are smoothed into soft images; ideal for reproducing maps P •   rinted matter: fine grids in illustrations and photographs on printed matter are reproduced without moiré artefacts D •   ark originals: line and text information in dark and lowcontrast originals such as diazo intermediates is enhanced and reproduced clearly   lueprints: in this mode black is printed as white and B • white is printed as black, significantly enhancing legibility   ut & paste: tape marks of cut & paste collages are C • filtered away to a clean copy Océ Image Logic has automatic halftoning, thresholding, sharpness and density in all original modes, so copies and scans are right first time without trial and error. [. . . ] This process prevents contact between the media and the photoconductor, eliminating the risk of damage to the photoconductor. Direct application of the toner via the CTF unit ensures 100 percent toner transfer, further contributing to image quality and minimising the risk of toner pollution. 6 Simple paper path along pre-heater Since the print image is brought to the paper and not the other way round, the paper path is simple and reliable -- so simple that jams are virtually eliminated. The paper is pre-warmed, allowing low fusing temperatures and preventing the media from warping or wrinkling. Photoconductor Productivity that’s incomparable This table shows a comparison between Océ Copy Press technology and conventional electro-photographic technology in the key areas of sensitivity to internal paper jams, copy and print quality and environmental issues. conventional electro-photographic technology Sensitivity to internal paper jams Issue 1. Paper path Problem Disadvantage Long paper path: through the middle of the machine to the sensitive photoconductor and fusing area 3-8 wire corona units: several charges are required to make a copy Complex internal mechanism results in many potential jam areas and wasted paper 2. corona units Charges generate excessive static electricity increasing chance of jams 3. Paper cutters 1 paper cutter is used to cut all different media rolls Rewinding of roll needed when different media sizes are used within a set, increasing chance of jams and reducing printing speed Less durable parts may result in more frequent paper jams and required service visits 4. Material use Less sturdy uncoated materials often used, including paper path guides (some machines weigh around 400 kg) Paper at room temperature passes through hightemperature process, past flat plating 5.  ensitivity to S humidity Paper can stick to condensation on flat plating, leading to paper jams 8 1 6 7 5 2 3 4 3 3 1. Paper path Solution Advantage Short, simple paper path: does not pass sensitive parts; the image is brought to the paper No internal jams in photoconductor area because images go past it instead of through it 2. Corona units Only 1 electrical charge is needed because of the highly efficient imaging system Virtually no static electricity and reduced chance of paper jams 3. Paper cutters 3 cutters; all 6 rolls are positioned for immediate cutting No time-consuming rewinding of rolls needed, resulting in less jams and higher productivity 4. Material use Robust coated metal plating and durable materials are used throughout the machine (machine weighs 939 kg) Paper is pre-heated before fusing and led via ribbed, coated plating Constant reliability over years of intensive use 5.  ensitivity to S humidity Virtually no jams because temperature differences and surfaces between paper and contact points are limited 9 6 5 2 3 4 1 1.
