    550-Sheet Feeder tray is identified as Tray 3, and the trays of the 1100-Sheet Feeder are identified as Tray 4 and Tray 5. Note The Phaser 6300/6350 printer supports the installation of only one 550-Sheet Feeder. Attempting to install a second results in an unsupported configuration error.

  • Page 49: Laser Light Intensity Control

    Laser Light Intensity Control The Laser Unit in the Phaser 6300/6350 printer has four laser diodes: one each for yellow, magenta, cyan, and black. The diode control circuitry adjusts the light intensity for each color automatically. Image data is transmitted to the laser diodes in the Laser Unit as digital signals.

  • Page 50: Process Control

    Process Control For stable printing, the parameters related to forming both the electrostatic and toner image are continuously monitored and adjusted by the printer. Parameter correction and control over the entire printing process is called “process control”. There are two main areas of control: Bias Control Toner Density Control...

  • Page 52: Led Light Density Ctd (Adc) Control Sensor

    High Area Coverage Mode The High Area Coverage mode delays page feeding giving the printer additional time to dispense toner. This mode compensates for images whose toner density exceeds the printer’s toner dispense capabilities. This typically occurs during continuous runs of images that drop the toner density for any color Developer below the reference value.

  • Page 53: Color Registration Control

    The amount of registration shift is calculated from the reference value determined in Step 1 and the patch density measured in Step 3. The laser write timing is changed to compensate for any registration shift. s6300-068 2-12 Phaser 6300/6350 Color Laser Printer Service Manual...

  • Page 54: Transfer Roller Control

    Transfer Roller Control Detecting the Transfer Roller The CTD (ADC) Sensor is used to detect the presence of the Transfer Roller. This determination is made whenever power is turned on, or a door is opened and closed. If the output of the CTD (ADC) Sensor is greater than the reference value the controller signals that the Transfer Roller is present.

    5 seconds later. If toner present is not detected after executing toner dispense three times and if Toner Cartridge dispense time is 0, the “Remove Ribbon From ‘x’ Cartridge” error displays. 2-14 Phaser 6300/6350 Color Laser Printer Service Manual...

  • Page 56: Fuser Control

    Fuser Control Fuser Temperature Control During Fuser temperature control the printer’s target temperature is set based on the media type. The Heat Roller surface temperature is controlled to match the target temperature by turning the heater lamp On and Off. The Heat Roller surface temperature is detected by two sensors.

  • Page 188: Power On Self Test (Post)

    Power On Self Test (POST) POST diagnostics provide a quick means of isolating a defective subsystem associated with the Image Processor Board and SDRAM. There are two kinds of POST faults: soft and hard. A soft fault is any fault that allows the operating system to initialize.

  • Page 190: Post Hard Fault Messages

    POST Hard Fault Messages POST indicates a hard fault by displaying a message on the Control Panel and blinking the fault code on the health and Control Panel LEDs. There are long and short blinks. A long blink is worth 5 and a short blink is worth 1. As an example, a blink pattern flashed as long, long, short, short, represents fault code 5+5+1+1=12, indicating a failure in the CPU interrupt test.
