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 44: 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). ■...
  • Page 45: Selective Control; Paper Pick

    Selective Control; Paper Pick Unless changed in printer setup, the default tray is Tray 2. Trays in the optional High- Capacity Feeder are identified as Tray 3 and Tray 4. The tray in the optional 500-sheet 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.
  • Page 46 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 47: Led Light Density Ctd (Adc) Control Of Sensor

    If toner density is too great (excess toner) and 16 dispense counts are required to subtract this amount, the adjustment is accomplished by subtracting 2 counts from the calculated PCDC count over each of the subsequent 8 prints. If the excess amount cannot be subtracted in 8 print cycles, it is subtracted in the ninth and subsequent prints.

    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 51: Toner Control

    Toner Control Toner Cartridge installation is detected by the Toner Present (CTG-In) Switch, and the presence of toner is detected by the Toner Low Sensor. These switches and sensors are provided for each toner color (CMYK), and detection is made for each individually. Toner Low Sensor The toner low sensor checks one color every 3.5 seconds, requiring 14 seconds to detect all four colors.
  • Page 52: 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.
