HP LaserJet M806 and HP LaserJet Flow MFP M830 - Removal and replacement: Formatter

This document provides the procedures to remove and replace the formatter board for the HP LaserJet Enterprise M806 and HP LaserJet Enterprise Flow MFP M830.

Mean time to repair: 10 minutes

Service level: Intermediate

To replace the formatter printed-circuit assembly (PCA) you will need to remove the hard-disk drive (HDD) or solid-state memory (SSM) storage device, DIMM, and the fax PCA (if installed) from the defective formatter and then reinstall them on the replacement formatter.

Before performing service

Turn the printer power off

  • Disconnect the power cable.

    Warning:

    To avoid damage to the printer, turn the printer off, wait 30 seconds, and then remove the power cord before attempting to service the printer.

  • Disconnect all cables and accessories attached to the formatter.

CAUTION:

This part contains components that are electrostatic discharge (ESD) sensitive. To reduce the possibility of ESD damage, always touch the sheet-metal chassis to ground yourself before touching an ESD sensitive part.

Use the table below to identify the correct part number for your printer, and then go to http://h20141.www2.hp.com/hpparts to order the part.

Required tools

  • No special tools are required to install this kit.

After performing service

Turn the printer power on

  • Connect the power cable.

  • Use the power switch to turn the power on.

To verify that the formatter is correctly installed, observe the following functions of the LEDs on the formatter:

  • The heartbeat LED (callout 1) illuminates if the formatter is functioning correctly.

    • While the product is initializing, the heartbeat LED illuminates solid red for about one second, and then turns solid green for about twenty seconds.

    • After the initialization sequence is complete, the heartbeat LED blinks continuously if the printer is functioning correctly.

  • The connectivity LED (callout 2) indicates that the formatter is completely seated. It illuminates green when the product power is turned on and stays green if the formatter is properly seated.

If the LEDs do not correctly function, turn the product power off, remove the formatter, and then reinstall it (make sure that the formatter is fully seated before tightening the thumbscrews).

  2. Unpack the replacement part from the packaging.

    CAUTION:

    Some parts are sensitive to electrostatic discharge (ESD). Always perform service work at an ESD-protected workstation or mat. If an ESD workstation or mat is not available, touch the sheet-metal chassis to provide a static ground before touching an ESD-sensitive assembly. Protect the ESD-sensitive assemblies by placing them in ESD pouches when they are out of the printer.

    Important:

    Make sure that all of the shipping materials (for example shipping tape) are removed from the replacement part prior to installation.

    Note:

    If the replacement part is a roller or pad, avoid touching the spongy part of it. Skin oils on the roller or pad can cause paper pickup and/or print-quality problems. HP recommends using disposable gloves when handling rollers or pads or washing your hands before touching rollers or pads.

  3. To install an assembly, reverse the removal steps.
