  • Page 373 (a) 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 predetermined length until the paper hits the resist roller.

  • Page 376 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 377 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 450 This Maintenance Manual is intended for the maintenance personnel and describes the field mainte- nance methods for Second Paper Feeder option of OKIFAX 5650 Facsimile Transceiver. Refer to the Instruction sheet of High Capacity Second Paper Feeder option for equipment handling and operation methods.
  • Page 451 OUTLINE Functions When the Second Paper Feeder is installed with the OKIFAX 5650 facsimile transceiver, the Second Paper Feeder is connected to the facsimile by a connector. The Second Paper Feeder supplies paper automatically through the operation of pulse motor (hopping), which is driven by signals sent from CPU of the Second Paper Feeder under the control of the facsimile.

  • Page 452: Mechanism Description

    MECHANISM DESCRIPTION General Mechanism The Second Paper Feeder feeds the paper into the facsimile by receiving the signal from the facsimile, which drives the pulse motor inside the Second Paper Feeder, and this motion is transmitted to rotate the one-way clutch of the hopping frame assembly. The paper is delivered from the hopper into the facsimile through the turning of the hopping roller and feed roller.
