  • Page 57 April, ’89 DRUM 1. Selenium Drum Selenium has the following important characteristics. 1. It can accept a high positive electrical charge in the dark. (The electri- cal resistance of selenium is high in the dark.) 2. It will dissipate the electrical charge on its surface when exposed to light.
  • Page 58 April, ’89 Drum Thermistor Unit The drum thermistor unit has two thermistors that detect the temperature of the drum surface. One (TH-1) is for the control of the drum heater, and the other (TH-2) is for bias compensation. Usually, these thermistors touch the drum surface. However, when the drum stay is removed, they are separated from the drum surface by a release mechanism.
  • Page 59 April, ’89 3. Drum Heater Circuit The main board monitors the temperature of the drum surface through TH-1. When the main board determines that the drum heater should be on, CN301- B15 goes LOW. This action energizes SSR10 on the ac drive board and 100 volts ac is applied to the drum heater.
  • Page 60 April, ’89 CHARGE 1. Corona Unit This copier uses a dual wire corotron and a highly sensitive selenium drum. The corona wires generate a corona of positive ions when the charge power pack applies a high positive voltage. The selenium surface of the drum receives a uniform positive charge (about +800 V) as it rotates past the corona unit.
  • Page 61 April, ’89 Corona Unit Ventilation The charge corona casing has three slots that allow air from the charge fan This airflow prevents an uneven build up to flow through the corona unit. of positive ions. The CPU turns on the charge fan by supplying a LOW signal at CN304-B18. The charge fan motor turns on 100 milliseconds before the main motor.
  • Page 62 30 April, ’89 Wire Cleaner Paper dust and/or toner particles on the charge corona wires may interfere with charging and cause low density bands on copies. The wire cleaner cor- rects this problem by automatically wiping the charge corona wires clean. Once every 5,000 copies, the wire cleaner is activated when the main switch is turned on.
  • Page 63 April, ’89 Charge Power Pack The circuit operation for the charge corona begins with the input of +24 volts to the power pack at CN232-6. This voltage powers the LEDs. This power Additionally, +24V enters the power pack at CN232-7. (VP) supply is used for the high voltage coronas.
  • Page 64: Introduction

    April, ’89 ERASE 1. Introduction After passing the charge corona unit, the surface of the drum is covered with a uniform positive charge. However, the entire surface is not needed to produce the copy. To reduce toner consumption and reduce the load on the cleaning unit, the erase unit removes the charge potential from the areas that will not be used.
  • Page 65 30 April, ’89 2. Side Erase and Leading/Trailng Eage Erase - Side Erase - Side erase discharges the drum potential on both sides of the image area. It overlaps the image slightly on either side as shown in the figure. This prevents the edge of the original from being copied.
  • Page 66 30 April, ’89 Erase Lamp Circuit This copier uses 88 LEDs in the erase lamp unit. The large number of LEDs allows fine control of the side erase margins. Shift register drivers control the LEDs. Initially, the RESET signal (LOW ac- tive) turns off all the shift registers.

  • Page 85: Toner Density Control

    April, ’89 5. Toner Density Control The CPU checks toner density by directly sensing the image density at the end of the first copy cycle after the main switch turns on, and at every fifth copy after that. On check cycles, a black sensor pattern is exposed after exposure of the original on the glass.
  • Page 86 30 April, ’89 - Toner Density Control - The image density sensor checks the density of the sensor pattern image once every 5 copy cycles. The CPU receives two voltage values directly from the sensor: the value for the bare drum (Vsg) and the value for the sen- sor pattern (Vsp) These two values are then compared to determine whether or not more toner should be added,...
  • Page 87 April, ’89 - Toner Supply - When the CPU energizes the toner supply clutch, the toner supply roller feeds toner to the developer tank for a set period of each copy cycle. This continues until the low toner density condition is recovered. This copier has two different ways of controlling the amount of toner sup- plied.
  • Page 88 April, ’89 Toner Supply Amount Supply Amount SP1O-3 in Detect Mode: SP1O-4 The factory setting is 30 %. - Toner End Detection - the image density sensor to detect a toner end condition. The CPU uses This method is effective in both detect and fixed supply modes. If the ratio of p to Vsg (Vsp/Vsg x 100) becomes greater than 18.8%, the toner cartridge.
  • Page 89: Image Density Control

    April, ’89 6. Image Density Control Image density is controlled by changing the strength of the positive bias volt- age that is applied to the development roller sleeve by the bias power pack. Applying a bias voltage to the development sleeve reduces the potential be- tween the development roller and the drum, thereby reducing the amount of toner that is transferred to the drum.

  • Page 92 ’89 April, Drum Temperature Compensation (V4): The increase in development bias between 15°C and 45°C When the switch on the bias power pack is on, the CPU monitors the drum temperature through a thermistor (TH-2), and it increases or decreases the bias voltage to compensate for temperature induced variations in drum sen- sitivity.
  • Page 93: Bias For Id Sensing

    April, ’89 Bias for ID Sensing In order to develop the ID sensor pattern consistently, the CPU applies a fixed bias level to the development roller at the end of each copy cycle. The fixed base bias is 410 volts and it is affected by drum cavity tempera- ture and drum rest time.
