  • Page 35: Fuser Temperature Control

    Fuser temperature control The fuser temperature control maintains the temperature of the fuser heater at its targeted temperature. The DC controller monitors the FUSER TEMPERATURE (FSRTH1, FSRTH2) signals and sends the FUSER HEATER CONTROL (FSRD) signal according to the detected temperature. The fuser heater control circuit controls the fuser heater depending on the signal so that the heater remains at the targeted temperature.

  • Page 36: Fuser Protective Function

    Fuser protective function The protective function detects an abnormal temperature rise of the fuser unit and interrupts power supply to the fuser heater. The following three protective components prevent an abnormal temperature rise of the fuser heater: DC controller ● The DC controller interrupts power supply to the fuser heater when it detects an abnormal ◦...

  • Page 37: Low-voltage Power Supply

    Low-voltage power supply The low-voltage power supply (LVPS) converts ACinput voltage to DCvoltage. The LVPS has two fuses on the PCA. The LVPS 24 V output is interrupted to the fuser and the high-voltage power supply if the cartridge-door interlock switch (SW501) is in the off position (cover open). WARNING! The product power switch only interrupts DC voltage from the LVPS.

  • Page 38: Overcurrent/overvoltage Protection

    Overcurrent/overvoltage protection The low-voltage power supply has a protective function against overcurrent and overvoltage to prevent failures in the power supply circuit. If an overcurrent or overvoltage condition occurs, the system automatically cuts off the output voltage. If the DC power is not being supplied from the low-voltage power supply, the protective function might be running.

  • Page 40: Laser/scanner System

    Laser/scanner system The laser/scanner system receives VIDEO signals from the DCC and the formatter and converts the signals into latent images on the photosensitive drum. The main components of the laser/scanner are the laser unit and the scanner motor unit. The DC controller sends signals to the laser/scanner to control the functions of these components.

  • Page 42: Electrophotographic Process, Image-formation System

    Image-formation system Electrophotographic process The electrophotographic process forms an image on the paper. Following are the major components used in the process: Toner cartridge ● Transfer roller ● Fuser ● Laser/scanner ● The DC controller uses the laser/scanner and HVPS to form the toner image on the photosensitive drum. The image is transferred to the paper and then fused.

  • Page 43: Image Formation Process

    Image formation process Each of the following processes function independently and must be coordinated with the other product processes. Image formation consists of the following processes: Latent-image formation block ● Step 1: Primary charging ◦ Step 2: Laser-beam exposure ◦ Developing block ●...

  • Page 44: Latent-image Formation Stage, Primary Charging, Laser Beam Exposure

    Latent-image formation stage During the latent-image formation stage, the laser/scanner forms an invisible image on the photosensitive drum in the toner cartridge. Primary charging Step 1: DC and AC biases are applied to the primary charging roller, which transfers a uniform negative potential to the photosensitive drum.

  • Page 45: Developing Stage, Toner Cartridge

    Developing stage Toner cartridge Step 3: In the toner cartridge, the developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image.

  • Page 47: Cleaning Stage

    The product uses an on-demand fuser method. The toner image is permanently affixed to the paper with heat and pressure. Figure 1-23 Fusing Fuser heater Brush Fuser film Toner Media Pressure roller Fuser bias Cleaning stage Step 7: The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case.

  • Page 48: Toner Detection

    The product uses a nonvolatile memory chip built into the toner cartridge. Toner-cartridge detection happens when the engine controller detects the presence of a genuine HP toner-cartridge that contains a memory chip. Toner detection happens as the engine controller reads or writes the data that is stored on the memory chip.

  • Page 49: Paper Trays, Pickup, Feed, And Delivery System

    Pickup, feed, and delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The product uses a motor and two solenoids to drive the rollers. Three paper-detection sensors detect paper as it passes through the product. If paper does not reach or pass each sensor within a specified time, the DCC determines that a jam has occurred and alerts the formatter.
