Pick-up and Separation and Drive Mechanism H547D502.WMF The pressure plate [A] aligns the leading edges of the pages of the document. When the machine starts feeding the document, the mechanical clutch in the ADF roller unit lifts up the pick-up rollers [B] to feed the bottom sheet of the document.
  • Page 29 SCANNER 21 May, 1999 Image Scanning H547D503.WMF The image sensor [B] consists of a row of 1728 photosensitive elements (Letter width x 8 dots/mm). The document reflects light from the LED array and the rod lens array focuses it onto the image sensor. Because of the short optical path inside the CIS, the focal depth is much shorter than for a CCD type scanner.

  • Page 37: Toner Supply

    PRINTING 21 May, 1999 2.2.5 TONER SUPPLY H547D519.WMF This machine uses mono-component toner, composed of resin and ferrite. The toner mixing bar [A] stirs and carries toner to the toner application roller [B]. The toner application roller supplies toner to the development roller [C]. The main motor drives the toner supply mechanism through a gear train.
  • Page 38 21 May, 1999 PRINTING Toner End Detection H547D516.WMF The toner end sensor [A] below the toner tank detects toner near-end. While the main motor rotates, the machine detects toner end by the voltage output from the toner end sensor. The voltage from the sensor is close to 5V when the toner tank is full and decreases when the toner is almost used up.

  • Page 39: Development

    PRINTING 21 May, 1999 2.2.6 DEVELOPMENT H547D519.WMF Overview The toner supply bar [A] stirs and carries toner to the toner application roller [B]. The toner application roller is a sponge-like structure which carries toner to the development roller [D]. As the development roller [D] turns past the toner metering blade [C], only a thin coating of negatively charged toner particles stays adhered.
  • Page 40 21 May, 1999 PRINTING Development Bias H547D518.WMF The power pack [A] applies one voltage to the toner application roller [B] and toner metering blade [C], and a different voltage to the development roller [D]. Bias Control (During Printing) The power pack applies a charge of -650V to the toner application roller, and -400V to the development roller.
  • Page 41 PRINTING 21 May, 1999 Bias Control (After Each Page) At the start and the end of any print process (including the cleaning mode), the power pack applies 0V to the toner application roller, and +250V to the development roller.

  • Page 46 21 May, 1999 PRINTING Pick-up and Separation Standard Cassette and Optional Paper Feed Unit The pick-up and separation mechanism is a separation pad type. The separation pad and the paper feed roller allow only one sheet to feed. Cross Reference Group 3 Facsimile Manual: section 4-5-4 The paper feed motor in the mainframe starts to rotate when the printer is ready for printing.
  • Page 47 PRINTING 21 May, 1999 Optional Paper Feed Unit H547D508.WMF The paper feed motor in the mainframe drives the paper feed mechanism through a gear train. When the optional paper feed unit is used, the paper feed motor turns counter-clockwise, driving the paper feed roller [A] and the transport roller [B], as shown.

  • Page 48: Registration

    21 May, 1999 PRINTING Paper Feed Priority If there is an optional paper feed unit and/or multi-purpose feeder installed in the machine, deciding paper feed priority is in accordance with the following rules: • If the machine has an optional multi-purpose feeder and all of the cassettes contain paper of the same size, the machine uses the optional paper feed unit first, the standard cassette second, and the multi-purpose feeder third.
  • Page 49 PRINTING 21 May, 1999 Jam Detection Condition Error Code Standard Cassette When the paper edge sensor does not turn on 9-07 within 2.6 seconds of the paper jam timing signal. When the registration sensor is not turned on 9-84 within 5.5 seconds after the paper edge sensor turns on.

  • Page 50: Transfer And Separation

    21 May, 1999 PRINTING 2.2.9 TRANSFER AND SEPARATION H547D526.WMF Instead of using a transfer corona wire, this machine uses a transfer roller, which touches the drum surface. The power pack [A] applies a constant current of +5.0 µA to the transfer roller [B]. The positively biased transfer roller pulls negatively charged toner off the drum.
  • Page 51 PRINTING 21 May, 1999 Cleaning Mode If the paper is smaller than the printed image, or if a paper jam occurs during printing, toner may transfer to the roller surface. To prevent this from occurring, the transfer roller is cleaned before the next printing run. While the machine is cleaning the transfer roller, the power pack supplies -1200V to the transfer roller, and charges the drum to -750V.

  • Page 52: Cleaning

    21 May, 1999 PRINTING 2.2.10 CLEANING H547D519.WMF The cartridge contains the cleaning unit and the used toner tank. The cleaning blade [A] removes any toner remaining on the drum after the image is transferred to the paper, and then brings the toner into the used toner tank [B]. There is no used toner overflow detection mechanism because the used toner tank is large enough for the lifetime of the cartridge.

  • Page 53: Fusing

    PRINTING 21 May, 1999 2.2.11 FUSING Fusing Lamp Control During printing, the machine keeps the fusing temperature at 190°C. If the printing operation continues for more than 3 minutes, the machine keeps the fusing temperature at 165°C. When the Energy Saver Key is pressed or the energy saver timer expires, the machine goes into an energy saver mode.

    SYSTEM FEATURES 21 May, 1999 2.3.4 PAGE SEPARATION AND DATA REDUCTION Incoming pages that are only slightly longer than the copy paper may be reduced in the sub-scan direction. Whether or not this happens depends on the settings of printer switches 04 and 05. Reduction Enabled If bit 0 of printer switch 03 is at 1 (Enabled), the data will be reduced in the page memory to fit on the copy paper.
