1 Theory of operation

NOTE: The name for this product was changed to include the word “Flow”. There is no functional difference between the HP Scanjet Enterprise 8500 fn1 (L2717A) and the HP Digital Sender Flow 8500 fn1 (L2719A). Service parts containing the product name have been updated to include the words “Digital Sender” and “Flow”.

The 8500 fn1 is a fleet-compliant network scanner with an integrated legal-size flatbed scanner and single-pass duplex automatic document feeder (ADF). The input tray for the ADF holds 100 pages of standard size paper and can scan at 60 pages per minute (ppm) for simplex scanning and 120 ppm for duplex scanning.

The product has three hardware subassemblies:

●Flatbed scanner and ADF assembly

●Network electronics assembly

●User interface (control panel) assembly

ENWW

ENWW

Flatbed scanner and ADF assembly

The scanner can scan paper up to 216 mm (8.5 in) x 863.6 mm (34 in) in size. Paper must be placed in the ADF input tray or on the flatbed glass before the scanning can be initiated. Output from the scanner is in .JPEG format and is transferred to a network using a Hi-Speed USB interface.

The major hardware components associated with this assembly are:

●ADF with an integrated scan module

●Flatbed scanner assembly

●Scanner control-board assembly

ENWW

Flatbed scanner and ADF assembly

Network electronics assembly

The network electronics assembly controls all functions within the product and provides a connection to the external gigabit network interface for the product. This assembly only accepts files from a USB interface in .JPEG format from the flatbed scanner and ADF assembly. The assembly stores the files on the encrypted hard disk drive for additional post-scan processing and routing based on the options selected by the user.

2 Removal and replacement

●Introduction

●Removal and replacement strategy

●Electrostatic discharge

●Required tools

●Types of screws

●Service approach

●Customer self repair (CSR) assemblies

●Internal assemblies

NOTE: Your product might not appear exactly as the one shown in the photos in this chapter. Although details such as the color of the external panels and covers might be different than your product, the procedures in this chapter are appropriate for your product.

ENWW

Introduction

This chapter describes the removal and replacement of field-replaceable units (FRUs) only.

Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide directions for difficult or critical replacement procedures.

HP does not support repairing individual subassemblies or troubleshooting to the component level.

Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly.

Incorrectly routed or loose wire harnesses can interfere with other internal components and can become damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.

Chapter 2 Removal and replacement

ENWW

Removal and replacement strategy

WARNING! Turn the product off, wait 5 seconds, and then remove the power cord before attempting to remove an assembly. If this warning is not followed, severe injury can result, in addition to damage to the product. The power must be on for certain functional checks during troubleshooting. However, disconnect the power supply during parts removal.

Never operate or service the product with the protective cover removed from the laser/scanner assembly. The reflected beam, although invisible, can damage your eyes.

The sheet-metal parts can have sharp edges. Be careful when handling sheet-metal parts.

CAUTION: Do not bend or fold the flat flexible cables (FFCs) during removal or installation. Also, do not straighten pre-folds in the FFCs. You must fully seat all FFCs in their connectors. Failure to fully seat an FFC into a connector can cause a short circuit in a PCA.

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. Do not overtighten. If a self-tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly.

TIP: For clarity, some photos in this chapter show components removed that would not be removed to service the product. If necessary, remove the components listed at the beginning of a procedure before proceeding to service the product.

ENWW

Removal and replacement strategy

Electrostatic discharge

	CAUTION:		Some parts are sensitive to electrostatic discharge (ESD). Look for the ESD reminder

when removing product parts. Always perform service work at an ESD-protected workstation or mat, or use an ESD strap. If an ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part.

Protect the ESD-sensitive parts by placing them in ESD pouches when they are out of the product.

ENWW

Required tools

●Torx screwdrivers, size 10, 15, and 20

●Small flat blade screwdriver

●Needle-nose pliers

●ESD mat or ESD strap (if one is available)

●Penlight (optional)

●USB thumbdrive

ENWW	Required tools 11

Types of screws

This table describes the screws that are used in the product 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.

WARNING! Make sure that components are replaced with the correct screw type. Using the incorrect screw (for example, substituting a long screw for the correct shorter screw) can cause damage to the product or interfere with product operation. Do not intermix screws that are removed with one component with the screws that are removed from another component.

TIP: 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.

Service approach

Before performing service

●Turn off the power using the power switch.

●Unplug the power cable and network cable.

●Place the product on an ESD workstation or mat, or use an ESD strap (if one is available). If an ESD workstation, mat, or strap is not available, ground yourself by touching the sheet-metal chassis before touching an ESD-sensitive part.

NOTE: Some procedures require that you backup product data prior to replacing the assembly.

Backup product data

To ensure that customer-specific configuration information and data are preserved, back up the product data to a portable USB storage device prior to removing these assemblies. Restore the data after replacing the assembly.

NOTE: You can also backup product data using the HP Embedded Web Server (EWS). The EWS backs up product data to a customer specified network folder instead of the products hard drive. See the product user guide for information.

1.From the Home screen on the product control panel, touch the Device Maintenance button.

2.Open the following menus:

●Backup/Restore

●Backup Data

●Backup Now

NOTE: Backups are stored on the hard disk drive, including regularly scheduled backups. You can export backups to a USB storage device from the hard disk drive.

3.Insert the portable USB storage device.

4.Touch Export Last Backup

5.Enter the password and confirm the password. Touch OK.

After performing service

●Connect the network cable, and then plug in the power cable.

NOTE: Some procedures require that you perform a restore step after to replacing the assembly.

ENWW	Service approach 15

Restore product data

NOTE: You can also restore product data using the Embedded Web Server (EWS). See the product user guide for information.

1.From the Home screen on the product control panel, touch the Device Maintenance button.

2.Open the following menus:

●Backup/Restore

●Restore Data

3.Insert the portable USB storage device.

4.Select the backup file, and then touch Restore.

5.Touch Restore.

Save and repair process

The save and repair process occurs automatically whenever the formatter PCA, interconnect PCA, or encrypted hard disk drive (HDD) are replaced. This process is transparent to the user.

CAUTION: Replacing the formatter PCA and interconnect PCA at the same time or swapping these assemblies between products can render the product unusable.

●Formatter PCA: When a replacement formatter PCA is installed and the product is turned on, NVRAM values from the interconnect PCA are transferred automatically to the replacement formatter PCA. This process allows the product to return to normal operation with all of the necessary product history.

●Interconnect PCA: When a replacement interconnect PCA is installed, NVRAM values from the formatter PCA are transferred automatically to the replacement interconnect PCA. This process allows the product to return to normal operation with all of the necessary product history.

●Hard disk drive (HDD): When a replacement hard disk drive is installed and product is turned on, the replacement hard disk drive is locked to the formatter PCA of the product. The encryption key is placed in the NVRAM of the formatter PCA and copied to the NVRAM of the interconnect PCA. This allows the backed up NVRAM values from the interconnect PCA to be restored to a replacement formatter PCA when either the formatter PCA or interconnect PCA are replaced. This process also allows the hard disk drive to function when it is transferred from a defective formatter PCA to a replacement formatter PCA. The hard disk drive cannot be used in another product or accessed from outside the product.

Post-service test

Perform the following test to verify that the repair or replacement was successful.

16 Chapter 2 Removal and replacement
