To load originals onto the flatbed scanner Make sure that the automatic document feeder (ADF) contains no media. Lift the scanner cover. Place the original document face-down on the flatbed scanner glass with the upper-left corner of the document at the lower-right corner of the glass.

  • Page 45: Tray

    To load originals into the ADF NOTE: The ADF capacity for the product is up to 50 sheets of 75 g/m (20 lb) media. Insert the stack of originals into the ADF input tray top-edge-first, with the media stack face-up and the first page to be copied on the top of the stack.

  • Page 47: Configure Trays, Change Tray Selection

    NOTE: When you add new media, make sure that you remove all of the media from the input tray and straighten the stack of new media. Do not fan the media. This reduces jams by preventing multiple sheets of media from feeding through the product at one time. Configure trays When using one of the trays for a specific size of paper, you can set the default size for the tray in HP ToolboxFX or from the control panel.

    Scanner and ADF functions and operation The following sections describe how the document scanner and the automatic document feeder (ADF) function. Scanner functions The scanner uses a light source, a color-separation method, and a charge-coupled device array (CCD) to collect optical information about the document and transform that into an image file. The scanner consists of these elements: ●...

  • Page 91: Scanner Operation, Adf Operation

    Scanner operation At power-on and periodically at other times, the scanner assembly moves systematically to locate its home position. It then calibrates to a white strip located under the glass at the right end of the scan tub. If the product detects a document in the ADF when a copy or scan is initiated (from the software or the control panel), the scan module moves to the left side of the scan tub and stops.

  • Page 99: Pickup/feed/delivery System

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

  • Page 102: Figure 4-11 Developing

    Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized. Step 3: Developing The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image.

    Figure 4-12 Transfer Step 5: Separation The elasticity of the print media causes its separation from the photosensitive drum. A static-charge eliminator aids separation by weakening any electrostatic adhesion. Figure 4-13 Separation Step 6: Fusing The DC negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering.

    NOTE: In order for the 1-2-3 sequence to work, the extension phone setting must be set to On in the Fax setup menu. Distinctive ring function Distinctive ring is a service that a telephone company provides. The distinctive ring service allows three phone numbers to be assigned to one phone line.

  • Page 107: The Fax Subsystem, Fax Card In The Fax Subsystem, Safety Isolation, Safety-protection Circuitry

    If you experience problems using the fax feature on a VoIP network, ensure that all of the product cables and settings are correct. Configuring the Fax Speed setting to Medium(V.17) or Slow(V.29) can also improve your ability to send a fax over a VoIP network. See Table 6-8 Fax setup menu on page 194.

    All communications cross the isolation barrier magnetically. The breakdown voltage rating of barrier- critical components is greater than 5 kV. Data path TIP and RING are the two-wire paths for all signals from the telephone network. All signaling and data information comes across them, including fax tones and fax data.

    Ring detect Ring detect is performed by the line voltage monitoring module of the silicon DAA, and is a combination of voltage levels and cadence (time on and time off). Both must be present to detect a valid ring. The CODEC works with DSP as well as the firmware to determine if an incoming signal is an answerable ring.
