  • Page 21 (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 22: Electrophotographic Process

    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.

    2.3.3 Process Operation Descriptions (1) Hopping and Feeding Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below: Registration motor Idle gear Registration roller Hopping roller Motor gear Registration gear Hopping gear The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b"...
  • Page 26 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 27 (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 28 (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 29 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 30 (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 31 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 32 (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 33 (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. A thermistor which is in contact with the heater roller regulates the temperature of the heater roller to a designated temperature in the menu, depending on the thickness of the paper (tray 1&2: light=165°C, medium light=170°C, medium=175°C, medium heavy and heavy=195°C/manual...
  • Page 34 (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. Image drum Cleaning roller Power supply Transfer roller (8) Cleaning of rollers The charge, transfer and cleaning rollers are cleaned for the following cases: •...
  • Page 35: Revision Of Led Head Illumination

    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.

  • Page 38 The LED driver (MSM6731BWAF) corrects the LED illumination by controlling the LED current. 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.

    Paper Jam Detection The paper jam detection function monitors the paper condition when the power is turned on and during printing. When any of the following conditions arises, this function interrupts the printing process.

    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.

    Centronics Parallel Interface The CPU sets a BUSY-P signal to ON at the same time when it reads the parallel data (PDATA1- P to PDATA 8-P) from the parallel port at the fall of PSTB-N signal. Furthermore, it makes the store processing of received data into a receive buffer terminate within a certain fixed time and outputs an ACK-N signal, setting the BUSY-P signal to OFF.

  • Page 216: Fuser Temperature Control

    Fuser Temperature Control For the temperature control by heater control, the variation in the resistance of the thermistor is A/D converted in IC2 and the resultant digital value is read and transferred to the CPU. The CPU turns on or off the HEATON-N signal according to the value of the signal received from IC2 to keep the temperature at a constant level.
  • Page 217 The temperature control is described below. Temperature ˚C HEATON-N 176˚C * The values V1 and V2 vary according to setting mode. 175˚C (Standard temperature) When Vt rises to V2 or more, the heater is turned off (by setting HEATON-N signal to LOW). When Vt drops to V1 or less, the heater is turned on (by setting HEATON-N signal to HIGH).
  • Page 218 For heater breakdown detection, the heater must first be turned on. When a temperature rise which corresponds to the switching on of the heater does not occur, then a heater breakdown is detected. To shorten the breakdown detection time, the following circuit is used. Immediately after the power is turned on, the thermistor is checked and THERM-CMP signal is turned on to turn the resistor Q44 on.
