  • Page 40: General Guidelines

    5CY/3B7 3-1 General guidelines The paper feeder may not be used to print on paper not satisfying the requirements below. Also, special types of print media such as overhead projection (OHP) film, envelopes, adhesive backed labels, and paper containing watermarks must not be used with printing with the paper feeder. These types can result in jams, misfeeds, and paper waste, and in extreme cases can damage the paper feeder.

  • Page 41: Selecting The Right Paper

    5CY/3B7 3-1-2 Selecting the right paper Copier/printer printing is a process involving laser light, electrostatic discharge, toner, and heat. In addition, as the paper passes through the copier/printer it undergoes considerable sliding, bending, and twisting motions. A high-quality printing paper matching the requirements withstands all these stresses, enabling the paper feeder and the copier/printer to turn out clean, crisp printed copy consistently.

  • Page 42: Paper Specifications

    5CY/3B7 3-2 Paper specifications The following table summarizes the basic paper specifications that should be applied to the paper used with the paper feeder. Details are given following the table. Table 3-2-1 Specifications Item Specification Weight 64 to 90 g/m (17 to 24 lbs./ream) Thickness 0.086 to 0.110 mm (3.4 to 4.3 mils)

  • Page 44: Moisture Content

    5CY/3B7 (7) Moisture content Moisture content is defined as the percent ratio of moisture to the dry mass of the paper. Moisture can affect the paper's appearance, feedability, curl, electrostatic properties, and toner fusing characteristics. The moisture content of the paper varies with the relative humidity in the room. When the relative humidity is high and the paper absorbs moisture, the paper edges expand, becoming wavy is appearance.

  • Page 45: Other Paper Properties

    5CY/3B7 3-2-2 Other paper properties (1) Porosity Refers to the density of the paper structure; that is, to how openly or compactly the fibers are bonded. (2) Stiffness Limp paper can buckle inside the paper feeder and the copier/printer, while paper that is too stiff may bind.

  • Page 46: Special Paper

    5CY/3B7 3-2-3 Special paper The following types of special paper can be used: Colored paper Preprinted paper Use paper that is sold specifically for use with photocopies and/or laser printers. Since the composition and quality of special paper very considerably, special paper is more likely than white bond paper to give trouble during printing.

    5CY/3B7 4-4 Paper feeding system The paper feeding system picks up paper from the paper cassette. At a precise timing, it feeds it to the copier/printer. The printed page is finally delivered to the internal tray/face-down tray, eject tray/face-up tray, or optional document finisher/sorter , document finisher and stacker. The figure below shows the components in the paper path within the copier/printer and paper feeder.

  • Page 61 5CY/3B7 As the copier/printer requests feeding paper, the main board activates the feed stepping motor, drives the feed shaft on the cassette, thus rotating the feed roller and the pickup roller, according to the paper feed timing. The pickup roller rotates to pull and feed the topmost paper on the stack on the bottom plate.

  • Page 62: Paper Cassette Feeding Drive System

    5CY/3B7 4-4-4 Paper cassette feeding drive system Rotation of the feed stepping motor rotates the feed shaft combined by feed gear. The drive of the feed shaft rotates the pickup roller through the feed roller and gear, and feeds paper from the cassette. Rotation of the feed stepping motor is always transmitted to the upper and lower feed shaft with the combination of the gear, and has become as rotate in the opposite direction.

  • Page 63: Paper Size Sensing

    5CY/3B7 4-4-5 Paper size sensing The size of the paper currently in the selected cassette is acknowledged to the engine board of the copier/printer by means of the on-off status of the paper size sensors PT1, PT2, and PT3 behind the paper stopper of the paper cassette.

  • Page 67 5CY/3B7 The rotating angle at which the paper level switch stops revolving depends on the amount of paper remaining, therefore, the more the paper remains in the cassette the greater the angle is. The rotating angle of the gear for the paper level switch varies in proportion with the rotating angle of the cassette base elevation motor in four positions.
