2.5 Electrophotographic Process 2.5.1 Electrophotographic Process Mechanism This mechanism actuates the printing of image data supplied by the control board on the paper by electrophotographic process. The layout of the electrophotographic process mechanism is shown in Figure 2-6.

(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, that is two-phase excited by the signal from the Main Control PCB. It drives the hopping and registration rollers via two oneway clutches according to the direction of rotation.
2.5.2 Electrophotographic Process The electrophotographic processing is outlined below. The electrophotographic printing process is shown in Figure 2-7. 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.

2.5.3 Process Operation Descriptions (1) Hopping and Feeding Hopping and feeding motions are actuated by a single registration motor in the mechanism as shown below: Idle gear Registration motor Registration roller a Hopping roller b Registration gear Motor gear Hopping gear The registration motor turning in direction "a" drives the hopping roller. The registration motor turning in direction "b" drives the registration roller.
(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 by the paper advance, the paper is further advanced to a predetermined distance until the paper hits the registration roller (the skew of the paper can thus be corrected).
(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 print data.
(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 supply Charge roller 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. When the DC voltage applied by the power supply exceeds the threshold value, charging begins.
(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. Charge roller LED head LED head Power supply Image drum Paper Image drum The image drum is coated with an underlayer (UL), a carrier generation layer (CGL), and carrier transfer layer (CTL) on aluminum base.
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 negative carriers flow into the aluminum layer (ground).
(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.
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.
(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.
(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 contact with the heater roller regulates the temperature of the heater roller at a predetermined level (about 165°C).
(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: • • • • Warming up when the power is turned on. Warming up after the opening and closing of the cover.
2.6 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. If any of the following errors is encountered, printing can be recovered by removing the jammed paper (by opening the upper cover, removing the jammed paper and closing the upper cover).

2.7 Cover Open When the stacker cover is opened, the cover open microswitch on the power/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 control board to notify that the microswitch is off, and the control board carries out the cover open process.
2.8 Toner Low Detection • Device The Toner Low Detection device consists of a stirring gear which rotates at a constant rate, a stirring bar and a magnet on the stirring bar. The stirring bar rotation is driven by the link to the protrusion in the stirring gear. Magnet Protrusion Stirring Bar • Stirring Gear Operation Toner Low is detected by monitoring the time interval of the encounter of the magnet set on the sensor lever and the magnet on the stirring bar.
TONER FULL state 240 ms < t1 < 1.5 sec TNRSNS-N t1 4.875 sec. TONER LOW state TNRSNS-N t1 t1 > 1.5 sec. or t1 < 240 ms 4.875 sec. • When the Toner Low state is detected 2 times consecutively, Toner Low is established. • When the Toner Full state is detected 2 times consecutively, Toner Low is cancelled. • When there is no change with the toner sensor for 2 cycles (4.875 sec. x 2) or more, then the Toner Sensor Alarm is activated.

(1) Reset Engine It resets all the Engine Menu contents to the factory default setting.
(4) Product set Product (ID) of the printer is set. Product which is available at present is only MDL (Model). Up to 32 alphanumeric characters can be inputted. The corresponding type is the type supporting the ID down- load command. For an unsupported type, no character can be inputted as light color display. (5) Printer name set The corresponding type is changed.
2-6 Correspondence to non-corresponding product ID printer When the ID of the printer is not corresponding, a dialog for selecting the corresponding printer name is displayed. When the printer name is set, it is registered in the initialization file and processed as a corresponding printer also for the next and subsequent startup. The following is a display example of a printer set dialog. Figure 4-5 The following five types of printer names can be set.
2-7 Reload Button The same setting as in the starting up of an application software can be made. It reads out the settings of the printer being connected.
