  • Page 2: Safety Information

    Safety Information Laser Safety This is a digital machine which prints by means of a laser. There is no possibility of danger from the laser, provided the machine is operated according to the instructions in this manual. Since radiation emitted by the laser is completely confined within protective housing, the laser beam cannot escape from the machine during any phase of user operation.
  • Page 3 The label shown on next page indicates compliance with the CDRH regulations and must be attached to laser products marketed in the United States. CAUTION: Use of controls, adjustments or performance of procedures other than those specified in this manual may result in hazardous radiation exposure. This is a semiconductor laser.

    2.3 Scanning Section 2.3.1 ADF Section When a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you will hear the short beep. The width of document is detected by DB4 and DA3 sensors and length of document is detected by DADFA3 and DADFLEG sensors.
  • Page 31 2.3.2 FBS section Light reflected from the original passes through three mirrors and a lens to form a reduced image on the CCD Sensor as the Scanner is moved by the Scanner Motor. The CCD sensor converts the light pattern (image data) into an electrical image signal.
  • Page 32 2.3.2.1 Exposure Section: Construction and Function 1 Reflector Tape When a book or other bound original is copied, the paper in the area near the binding generally fails to come flush against the glass, so that the copy of these areas is generally too dark. The Reflector Tape reduces this problem by reflecting light from the Exposure Lamp onto these areas of the original.
  • Page 33 2.3.2.3 Original Size Detection Timing The copier CPU affirms and resets the readings of the original size at the following timings. Takes size readings: When the BIS sensor is deactivated. Affirms size readings: When the Start key is pressed with the BIS sensor activated or the APS sensor deactuated. Resets size readings: When the APS sensor is deactuated.

  • Page 40 2.4.5 PC Drum The PC Drum used in this machine is the organic photoconductor (OPC) type. The drum consists of an aluminum base coated with a charge generation layer and a charge transport layer. Handling Precautions Prolonged exposure to light can cause the photoconductor surface of the drum to suffer light fatigue, resulting in a loss of photosensitivity.

  • Page 41: Drum Charging

    2.4.6 Drum Charging A scorotron charger system generates a negative DC corona discharge onto the PC Drum surface. The grid mesh ensures uniform charging. The grid voltage (Vg) applied to the grid mesh is controlled by the constant voltage circuitry within the High Voltage Unit.

  • Page 42: Erase Lamp

    2.4.7 Erase Lamp Any potential remaining on the surface of the PC Drum is neutralized by both light from the Erase Lamp and a DC negative voltage applied by the Charge Neutralizing Sheet. The Charge Neutralizing Sheet applies a negative charge on the surface of the PC Drum which is positively charged by the Image Transfer Roller.

  • Page 45 2.4.8.2 Laser Emission Timing (SOS Signal) The signal output from the Master Board triggers the firing of the laser. The laser beam travels to the Polygon Mirror, lens, and SOS Mirror to eventually hit the SOS Sensor, which generates an SOS signal. The SOS signal determines the laser emission timing for each line in the main scanning direction.

  • Page 46: Developing Unit

    2.4.9 DEVELOPING UNIT The Toner Conveying Rollers mix the toner and carrier particles together and carry the toner/carrier mixture up to the Sleeve/Magnet Roller. The magnetic brush formed on the surface of the roller allows the toner to come into contact with the charges on the surface of the PC Drum, thus forming an electrostatic latent image.
  • Page 47 2.4.9.1 Sleeve/Magnet Roller This machine employs the MT-HG system with a Sleeve/Magnet Roller having the following magnetic characteristics. Turning of the sleeve surrounding the Magnet Roller ensures that fresh developer from the Developer Mixing Chamber is always being conveyed to the point of development with respect to the PC Drum. : The point of development with the maximum magnetic flux density which ensures that the carrier is firmly held onto the Sleeve Roller when toner is attracted to the latent image.
  • Page 48 2.4.9.2 Developing Bias The amount of toner attracted onto the surface of the PC Drum is controlled by varying the developing bias voltage. As the PC Drum deteriorates and its photoconductive layer begins to wear, it becomes more sensitive to the increase in the amount of toner.

    2.4.9.3 ATDC Sensor The ATDC Sensor automatic adjustment is made when a new I/C is installed in the machine. Toner replenishing control is thereafter controlled as detailed in the following. 1. ATDC Sensor Automatic Adjustment The ATDC Sensor is automatically adjusted when a new I/C is loaded in the machine. During this sequence, the machine reads the sensor output value and sets it as the reference.

    2.4.9.5 Sub Hopper Toner Empty Detecting Mechanism A toner-empty condition in the Sub Hopper is detected by the Magnet Lever that moves up and down as the Sub Hopper Toner Agitating Lever turns and actuates and de-actuates the Sub Hopper Toner Empty Switch.
  • Page 52 2.4.9.6 Main Hopper Toner Replenishing Mechanism When a toner-empty condition in the Sub Hopper is detected, the Main Hopper Toner Replenishing Motor is energized to turn the Toner Bottle, thereby supplying toner from the Main Hopper to the Sub Hopper. The Toner Bottle Home Position Sensor mounted on the coupling ensures that the Toner Supply Port in the Toner Bottle is positioned at the top whenever the bottle is stopped.

  • Page 55 2.4.10.2 MP Cassette-in-Position Detection When the MP Cassette is slid into the machine, the light blocking plate located in the rear of the cassette blocks the Cassette Set Sensor and the machine determines that the MP Cassette has been slid into position.
  • Page 56 2.4.10.3 MP Cassette Paper Empty Detection Two sensors are used in this machine: the Paper Empty Sensor detects a paper-empty condition, while the Paper Near-Empty Sensor detects a paper near-empty condition. Paper Near-Empty Detection: A paper near-empty condition is detected as the paper is consumed and when the Near-Empty Lever lowers to eventually block the sensor (L).
  • Page 57 2.4.10.4 MP Cassette Paper Size Detection The Paper Size Detecting Board detects the length of the paper (FD). A lever is connected to the Trailing Edge Stop of the cassette and, as the stop is slid to the size of the paper loaded in the cassette, the lever is moved to turn ON and OFF the size detecting switches mounted on the machine side.

  • Page 61: Paper Dust Remover

    2.4.11.2 Paper Dust Remover The Paper Dust Remover is installed so that it makes contact with the Left Synchronizing Roller. It is intended for preventing paper dust from sticking to the surface of the PC Drum. As the roller turns in contact with the Paper Dust Remover, triboelectric charging occurs, which attracts paper dust from the paper that passes between the two rollers and the dust is, in turn, transferred onto the Paper Dust Remover.

  • Page 62: Image Transfer And Paper Separation

    2.4.12 IMAGE TRANSFER AND PAPER SEPARATION Image Transfer This machine employs an Image Transfer Roller to transfer the image to the paper. The High Voltage Unit applies an image transfer current to this roller. To ensure that image transfer efficiency is stabilized, the image transfer current is automatically varied according to the paper size, paper type, and the B/W ratio of the original.

  • Page 369: Paper Empty Detection

    Paper Feed Unit Options 6.4.1.6.6 Paper Empty Detection • When the cassette runs out of paper, the actuator for the Paper Empty Sensor drops into the cutout in the Paper Lifting Plate. This unblocks the sensor and the machine detects that the cassette has run out of paper.

  • Page 370: Paper Separating Mechanism

    Options Paper Feed Unit 6.4.1.6.7 Paper Separating Mechanism • Each cassette has fingers that function to separate the top sheet of paper from the rest of the paper stack at paper take-up. The fingers are fitted to the right front and rear corners of the cassette. When the Paper Take-Up Roll starts turning to take up the top sheet of paper, its turning force is directly transmitted to the top sheet of paper as it is in direct contact with the Paper Take-Up Roll.
  • Page 371 Paper Feed Unit Options 6.4.1.6.8 Paper Take-Up Roll • Since the Paper Lifting Plate is raised at all times by the Paper Lifting Springs, paper is wedged in the mechanism when the cassette is slid out of the machine if the Paper Take-Up Roll is round in shape. So the roll is semicircular and the circular part of the roll is positioned on top at times other than take-up.
