2 - 16 2.5.3 Process Operation Descriptions (1) Hopping and Feeding Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below: The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller. Th[...]

2 - 17 (a) Hopping 1 For hopping, the registration motor turns in direction "a" (CW direction) and drives the hopping roller to advance the paper until the inlet sensor turns on (in this case, the registration gear also turns, but the registration roller is prevented from turning by the one-way bearing). 2 After inlet sensor is turned on [...]

2 - 18 (b) Feeding 1 When hopping is completed, the registration motor turning in direction "b" (CCW direction) drives the registration 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 bearing). 2 The paper is further advanced, synchronization to the pr[...]

2 - 19 (2) Charging Charging is actuated by the application of the DC voltage to the charge roller that is in contact with the image drum surface. The charge roller is composed of two layers, a conductive layer and a surface protective layer, both having elasticity to secure good contact with the image drum. When the DC voltage applied by the power[...]

2 - 20 (3) Exposure Light emitted by the LED head irradiates the image drum surface with a negative charge. The surface potential of the irradiated portion of the image drum drops, forming an electrostatic latent image associated with the image signal. The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier t[...]

2 - 21 The image roller surface is charged to about –750 V by the contact charge of the charge roller. When the light from the LED head irradiates the 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 image drum. Likewise, the n[...]

2 - 22 (4) Developing Toner is attracted to the electrostatic latent image on the image drum surface, converting it into a visible toner image. Developing takes place through the contact between the image drum and the developing roller. 1 As the toner supply roller rotates while rubbing on the developing roller, a friction charge is generated betwe[...]

2 - 23 Note: The bias voltage required during the developing process is supplied to the toner supply roller and the developing roller, as shown in the diagram below. –450 VDC is supplied to the toner supply roller, –300 VDC to the developing roller. Connected and bias supplied when the cover is closed Image drum Base Developing roller Toner sup[...]

2 - 24 (5) Transfer The transfer roller is composed of conductive sponge material, and is designed to get the image drum surface and the paper in a close contact. Paper is placed over the image drum surface, and the positive charge, opposite in polarity to that of the toner, is applied to the paper from the reverse side. The application of a high p[...]

2 - 25 (6) Fusing When the image transfer is completed, the toner image is fused to the paper by heat and pressure as the paper with unfused toner image passes between the heater roller and the back-up roller. The heater roller with Teflon coating incorporates a 400W heater (Halogen lamp), which heats the heat roller. A thermistor which is in conta[...]

2 - 26 (7) Cleaning When the transfer is completed, the residual toner left on the image drum is attracted to the cleaning roller temporarily by static electricity, and the image drum surface is cleaned. (8) Cleaning of rollers The charge, transfer and cleaning rollers are cleaned for the following cases: • Warming up when the power is turned on.[...]
