Device information

The HP Digital Sender 9250c converts black-and-white and color documents, drawings, and photographs into an electronic form and then distributes them directly to several kinds of destinations. You can also install the included HP Digital Sending Software (HP DSS) program to use advanced digital sending features such as send-to-workflow with optical character recognition (OCR).

Installing the device is simply a matter of connecting it to your network and configuring the digital-sending features. The digital sender operates as a standalone unit on the network and does not require network privileges for administration.

Where to get more information

The following table outlines the digital sending features that are available, and where to find more information about these features. All of the documentation listed in this table can be found on the documentation CD that came in the box with the device.

Feature Description For more information

Scan to E-mail Scan a document and send it to any e-mail

address.

Scan to Folder Scan a document to a network folder. More

than one folder destination can be configured.

Address Book for E-mail and Fax

User PIN Authentication Enter names and personal identification

LDAP Addressing Configure the device to search an LDAP

LDAP Authentication Configure the device to require user

Enter names and e-mail addresses or names and fax numbers for e-mail and fax recipients into the device's address book. This feature can also be used to manage the fax speed dials list.

numbers (PIN) so that only authorized users can use specific features of the device.

ENWW Chapter contents 25

Basic operation

All high-level digital sender processes are routed through the formatter, which processes images and communicates with other devices.

The basic digital sender operation can be divided into three systems:

The engine control system, which includes the power supply and the scanner controller board

●

The pickup-and-feed system, which consists of various rollers and transports the media through

●

the ADF

The scanner system, which scans documents and sends them to the formatter in the form of data

●

Sequence of operation (scanner)

Period (sequence) Description

Power on The period of time from when the digital sender power is turned on until the main motor begins

to rotate.

Initialization The period of time after the initial power-on sequence and before the digital sender is ready

to scan. During this time, the scanner and ADF initialization is completed, scanner calibration is performed, and the ADF checks for media in the input tray.

Standby The period of time from the end of the initialization sequence until a request for a scan. During

this time, the scan carriage is in the Home position and the digital sender might go into Sleep mode.

Scan The period of time immediately following a request for a scan. The scanner fan turns on, the

scan start position is adjusted, the digital sender performs the scan, and data is sent to the formatter.

26 Chapter 4 Theory of operation ENWW

Formatter system

The formatter is responsible for the following procedures:

Controlling Sleep mode

●

Receiving and processing scan data

●

Monitoring control-panel functions and relaying digital-sender status information (through the

●

control panel and the network)

Developing and coordinating data placement and timing with the scanner controller board

●

Communicating over the network

●

The formatter provides the electrical interface and mounting locations for one EIO card, one memory DIMM, and the hard-disk drive. The formatter also provides two internal USB host ports (for third-party devices), one external USB host port, and one external USB device port.

Sleep mode

This feature conserves power after the digital sender has been idle for an adjustable period of time. When the digital sender is in Sleep mode, the control-panel backlight is turned off, but the digital sender retains all settings. The default setting is for Sleep mode to be enabled, and the digital sender enters the Sleep mode after a 30-minute idle time. Sleep mode can also be turned off from the

Administration menu.

CPU

The digital sender exits Sleep mode and enters the warm-up cycle when any of the following occurs:

A PML or PJL command is received

●

panel

The top cover is opened

●

Media is placed in the input tray

●

NOTE: Digital-sender error messages override the Sleep message. The digital sender enters

Sleep mode at the appropriate time, but the error message continues to appear.

The formatter incorporates a 480 MHz RISC processor.

ENWW Formatter system 27

Memory

The formatter system contains the digital sender memory, which is divided into several components. This section describes each memory component.

NOTE: If the digital sender encounters a problem when managing available memory, a

clearable warning message appears on the control panel.

Hard-disk drive. The digital sender comes standard with a hard disk that has a capacity of 40 GB

●

or greater. The hard disk is used to store settings.

Random-access memory on the formatter. The random-access memory (RAM) contains the

●

scanned image. Memory capacity can be increased by adding a dual inline memory module (DIMM) to the formatter or replacing an existing DIMM with a larger DIMM. In most cases, additional memory might be required to use the digital sender with certain other devices, such as third-party devices. Typically, adding memory will not increase the performance of the device.

Nonvolatile memory. The digital sender uses nonvolatile memory (NVRAM) to store I/O

●

information and other permanent information, such as page counts and serial number. The contents of NVRAM are retained when the digital sender is turned off or disconnected.

Control panel

The control panel contains both touchscreen and hard keys, and sends user commands to the formatter.

Keyboard

The keyboard tray contains a keyboard for entering e-mail addresses and other data.

Scanner controller board

The scanner controller board sends data to the formatter and receives commands from the formatter. The scanner controller board controls motors, fans, and sensors.

Engine control system

Engine power supply circuit

The power supply consists of a low-voltage circuit. The low-voltage circuit provides uninterrupted 5 volt (V) and 3.3 V power to the formatter, and provides 24 V, 5 V, and 3.3 V power to the scanner controller board.

The scanner lamp illuminates a small strip of the document that is called the raster line. The mirrors direct the light through the lens to the CCD. The CCD senses and records the light, creating an analog representation of the raster line. If the ADF is being used, the document then advances in the ADF to the next raster line. If the flatbed is being used, the carriage advances to the next raster line. This advancing and collection process continues to the end of the sheet.

ADF feed system

The ADF has built-in duplexing capability for scanning two-sided documents. Pages from the original document enter the ADF from the ADF input tray. A separation roller and separation pad work together to separate the top sheet from the stack. The page passes through a set of registration rollers and two sets of feed rollers that advance the page. A set of delivery rollers delivers the page to the ADF output bin. A bin-full sensor detects when the ADF output bin is full and stops the feed mechanism until the bin is emptied.

Jam detection

When the sensors inside the ADF detect a jam, the feed and read motors immediately stop. A signal is sent to the scanner controller board, which notifies the formatter. An error message appears on the control-panel display.

To clear a jam, open the jam-access cover and remove the media. When sensors do not detect media after entering the jam state, the jam message is cleared from the control-panel display.

Residual-media jam

During the initialization sequence or after the ADF jam cover has been opened and closed, if the registration sensor, read sensor, or exit sensor detects the presence of media, the scanner controller board determines that a residual-media jam has occurred.

ADF pickup jam

If the leading edge of the media did not reach the registration sensor within a specific period of time, the scanner controller board determines that an ADF pickup jam has occurred.

ADF jam

ADF jams can occur in three places inside the ADF.

Registration-sensor jam

If the registration sensor does not detect the trailing edge of the media after the leading edge reaches the scan-ready position, the scanner-controller board determines that an ADF jam has occurred.

Also, when the scanner duplexer is in use, if the registration sensor does not detect the leading edge of the media after a specific period of time after media enters the duplexer, the scanner-controller board determines that an ADF jam has occurred.

Read-sensor jam

If the read sensor does not detect the leading edge of the media within a specific period of time, or if the read sensor does not detect the trailing edge of the media within a specific period of time after it detects the leading edge, the scanner-controller board determines that an ADF jam has occurred.

Exit-sensor jam

If the exit sensor does not detect the leading edge of the media within a specific period of time after the leading edge reaches the read sensor, or if the exit sensor does not detect the trailing edge of the media within a specific period of time after the read sensor detects the trailing edge, the scanner-controller board determines that an ADF jam has occurred.

ADF cover-open jam

If the ADF jam-access cover is opened while media is feeding through the ADF, a jam occurs.

ADF open jam

If the ADF is opened while media is feeding through the ADF, a jam occurs.

Screws that are used in the digital sender

This table describes the screws that are used in the digital sender and provides guidelines to help determine where each type of screw is used. The screws can vary in length depending on the thickness of the material that is being fastened. Always note where each type of screw is located and replace each one in its original location.

NOTE: When you are disassembling the product, place the screws into the chassis holes from

which they were removed. This prevents their loss, and ensures that the proper type and length of screw for each location is used when the product is reassembled

Table 5-1 Common fasteners that are used in this digital sender

Drawing and description Purpose

This screw is used to fasten metal to metal when good electrical contact is needed. This screw also provides high resistance to loosening.

Phillips-head machine screw with captive star washer

This screw is used to fasten sheet metal or plastic to plastic frames. The deep, coarsely spaced threads provide an increased holding capability while decreasing the possibility of stripping the target hole.

Upgrade the firmware on page 148.

Phillips-head screw with self-tapping threads

Phillips washer-head machine screw with a broad, flat washer attached to the screw head

Screw measurement guide

NOTE: To install a self-tapping screw, first turn it counterclockwise to

align it with the existing thread pattern, and then carefully turn it clockwise to tighten it. You will feel resistance and hear the screw click when it engages the existing threads in the hole. Do not overtighten the screw. If a self-tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly.

This screw is used to fasten sheet metal parts to the sheet metal chassis. It spans large clearance holes and distributes the load by increasing the bearing surface.
