  • Page 23 (1) Image Drum Unit The image drum unit consists of a sensitive drum, a charger, and a developer. The unit forms a toner image on the sensitive drum, using a electrostatic latent image formed by the LED head. (2) Registration Motor The registration motor is a pulse motor of 48 steps/rotation with two-phase excitement by the signal from the main control board.
  • Page 24 2.3.2 Electrophotographic Process The electrophotographic processing is outlined below. The electrophotographic printing process is shown in Figure 2-4. 1 Charging The surface of the image drum is charged uniformly with a negative charge by applying the negative voltage to the charge roller. 2 Exposure Light emitted from the LED head irradiates the negatively charged surface of the image drum.

The registration motor turning in direction "b"...
  • Page 28 Hopping 1 For hopping, the registration motor turns in direction "a" (clockwise 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).
  • Page 29 (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. Power Charge roller supply Image drum 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.
  • Page 30 (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. LED head LED head Charge roller Power...
  • Page 31 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.
  • Page 32 (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 between the developing roller and the toner, allowing the toner to be attracted to the developing roller (the developing roller surface is charged positive and the toner, negative).
  • Page 33 Note: The bias voltage required during the developing process is supplied to the toner supply roller and the developing roller, as shown below. –500 VDC is supplied to the toner supply roller, –265 VDC to the developing roller. Connected and bias supplied when the cover is closed.
  • Page 34 (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.
  • Page 35 (6) Fusing When the 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 generates heat.
  • Page 36 (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.

    2.3.4 Revision of LED Head Illumination An LED correcting head, which is capable of correcting the illumination of the LED for each dot, is being used in this printer. LED illumination correction function of 16 steps is carried out by using an EEPROM which is installed in the LSI that maintains the LED illumination correction values, and an LED correction drivers (MSM6731BWAF or MSM6732BWAF) together as a pair.

The LED illumination can be set in 16 steps, with 7 steps in the direction of illumination increase in relation to the standard value, and 8 steps in the direction of decrease. For this reason, the LED correction data is a 4-bit data for each dot.

    Cover Open When the stacker cover is opened, the cover open microswitch on the power supply/sensor board is turned off to cut +5V supply to the high voltage power supply circuit. This results in the interruption of all high-voltage outputs. At the same time, the CVOPN signal is sent to the main control board to notify that the microswitch is off, and the main control board carries out the cover open process.
