  • Page 512 (2) Printing and warm-up At warm-up Transfer gear Resist gear Hopping gear Rotate the pulse motor (main) in the a direction. The planetary gear rotates in the a’ direction, dislocating its position in the a” direction. This causes the planetary gear to be separated from gear A. The hopping gear will not rotate.
  • Page 513 (3) Charging Charging is performed by applying DC voltage to the charge roller that is in contact with the surface of the OPC drum. High- voltage power supply (4) Exposure Light emitted from the LED head irradiates the negatively charged surface of the OPC drum. The surface potential of the irradiated surface attenuates to form the electrostatic latent image corresponding to the image signal.
  • Page 514 (5) Development The electrostatic latent image on the surface of the OPC drum is changed to a visible toner image by applying a toner to it. Development is performed in the contact part between the OPC drum and developing roller. 1 The sponge roller negatively charges a toner and applies it to the developing roller.
  • Page 515 (6) Transfer The transfer roller is composed of conductive sponge material. This roller is set so that the surface of the OPC drum and sheets of paper will adhere closely. A sheet of paper is placed on the surface of the OPC drum and the positive charge opposite to the negative charge of a toner is applied from the reverse side by the transfer roller.
  • Page 516 (7) Fusing The transferred unfused toner image is fused to a sheet of paper because heat and pressure are applied when it passes between the heat roller and back-up roller. The Teflon-coated heat roller contains a 400 W heater (Halogen lamp) that heats the heat roller. The thermistor on the surface of the heat roller keeps the temperature of the heat roller constant.

Resist motor Motor gear Turning the resist motor in the "a" direction drives the hopping roller. Turning the resist motor in the "b"...
  • Page 524 Hopping Hopping turns the resist motor in the "a" direction (in the CW direction) and drives the hopping roller to advance the paper until the inlet sensor turns on. (In this case, the resist gear also turns, but the resist roller is prevented from turning by the one-way clutch gear.) After the paper has turned on the inlet sensor, the paper is further advanced by a predeter- mined length until the paper hits the resist roller.
  • Page 525 Feeding After end of hopping, turning the resist motor in the "b" direction (in the CCW direction) drives the resist roller to advance the paper. (In this case, the hopping gear also turns, but the hopping roller is prevented from turning by the one-way clutch gear.) The paper is further advanced in synchrony with the print data.
  • Page 526 Charging Charging is affected by applying a DC voltage to the charge roller thta is in contact with the EP (image) drum surface. The charge roller is composed of two layers consisting of a conductive layer and a surface protective layer that has elasticity, in order to secure a good contact with the EP (image) drum. When the DC voltage (-1.35 KVDC) applied from the Power Supply Unit exceeds a threshold value, charging begins.
  • Page 527 Exposure Light emitted from the LED head irradiates the EP (image) drum surface with negative charges. The surface potential of the irradiated part of the EP drum drops, thereby forming an electrostatic latent image associated with the image signal. Charge roller EP drum The EP (image) drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on the aluminum base.
  • Page 528 The EP (image) drum surface is charged to about -750 V by the contact charge of the charge roller. When light from the LED head irradiates the EP (image) drum surface, the light energy generates positive and negative carriers in the CGL. The positive carriers are moved to the CTL by an electrical field acting on the EP (image) drum.
  • Page 529 Developing Toner is attracted to the electrostatic latent image on the EP (image) drum surface to convert it into a visible toner image. Developing takes place at the contact between the EP (image) drum and the developing roller. As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated between the developing roller and the toner, allowing the toner to be attracted to the developing roller.
  • Page 530 Note: The toner supply roller and the developing roller are supplied with bias voltages required during the developing process as shown below. -450 VDC is supplied to the toner supply roller, -300 VDC to the developing roller. 40055101TH Rev.4 Developing roller Base EP drum Connected and bias voltage...
  • Page 531 Transfer The transfer roller is composed of conductive sponge material and is designed to make the EP (image) drum surface and the paper closely into contact. Paper is placed over the EP (image) drum surface, and a positive charge, opposite in polarity to the toner, is applied to the paper from its reverse side.
  • Page 532 Fusing After the end of the transfer operation, the unfused toner image is fused on the paper under heat and pressure as it passes between the heater roller and the back-up roller. The heater roller with a Teflon coating incorporates a 500 W heater (Halogen lamp), which heats the heat roller. A thermister, which is in contact with the heater roller, regulates the heater roller at a predeter- mined temperature (about 185 ˚C for OKIFAX 5000 series).
