    Printer Theory of Operation Summary of the Printing Process The Phaser 6250 Color Laser Printer is a ‘full-color laser printer’, that utilizes electrophotographic recording principals to place a full color image onto the print media. The system, contains a drum and developing unit for each color (yellow,...
  • Page 43 surface is attracted by the high positive potential and transfers to IDT1. During this transfer, the remaining negative charge on the drum is neutralized by the high positive charge on IDT1. 5. Secondary Transfer (IDT1 --> IDT2): The toner images formed on both IDT1 surfaces are then transferred onto the surface of IDT 2 to create a complete, 4-color toner image.

  • Page 45: Print Modes

    Print Modes There are three print modes: Draft mode, Enhanced mode, and Photo mode. These are based on the resolution (600 dpi or 2400 dpi) and, depending on the media type, can also be affected by process speed (full speed/half speed/one-third speed). Draft mode: 600 X 600 dpi resolution.

  • Page 46: Selective Control; Paper Pick

    Feeder is identified as Tray 3. Laser Light Intensity Control The Laser Unit in the Phaser 6250 printer has four laser diodes: one each for yellow, magenta, cyan, and black. The diodes control circuits adjust the light intensity for each color automatically. Image data is transmitted to the laser diodes in the Laser Unit as digital signals.
  • Page 47 Bias control operates as follows: The Temperature/Humidity Sensor sets the target values of the drum charging voltage and biasing DC voltage. Bias control test patches (see the adjacent figure for About 11mm patch configuration) of each of the four toner colors (yellow, magenta, cyan, and black) are generated and transferred to the Transfer Roller.

  • Page 48: Led Light Density Ctd (Adc) Control Of Sensor

    For exact density measurement, the sensor output value (reflected light density) must be the specified value when no toner is put on the Transfer Roller. The reflected light density varies Phaser 6250 Color Laser Printer Service Manual...

    depending on the Transfer Roller surface condition or dirty condition of CTD (ADC) sensor surface. The light density emitted from the LED is controlled so that the reflected light density meets the specified value. This control is implemented in two ways: Sets the light density so that the light reflected satisfies a specific value.

    Transfer Roller Assembly Control Detecting the Installation of the Transfer Roller Assembly Although there is no seperate sensor for this, the output of the CTD Sensor is used to detect installation or absence of the Transfer Roller when power to the printer is turned on, or the front cover is opened and closed.

  • Page 53: Fuser Control

    Fuser Control Fuser Temperature Control During fuser temperature control the printer’s target temperature is set. The heat roller surface temperature is controlled to match the target temperature by turning the heater lamp on/off. The heat roller surface temperature is detected by two sensors. A non-contact sensor in the middle of the roller is checked for 60ms and the Temperature Sensor at the edge of the roller is checked for 20ms to maintain an even temperature across the roller.
