NOTE:If the product has a parallel port, the word “parallel” will be in place of “USB” in the message. If the product has both USB and parallel ports, use the port defined in the message. If the incorrect port is used, the recovery will not be successful.?? NOTE:Network ports may not be used to recover HP LaserJet products.Connect a USB cable between the product and the computer to be used for the recovery.?? NOTE:If you have a Hewlett-Packard HP LaserJet USB Upgrade driver already installed on the computer being used for recovery, proceed to Step 4. A Windows Plug and Play event should begin. A text bubble should read: “Hewlett-Packard HP LaserJet USB Upgrade found” and the Found New Hardware Wizard will automatically start.?? NOTE:If you do not have a Hewlett-Packard HP LaserJet USB Upgrade driver already defined on the computer being used for recovery and do not receive a Plug and Play event, you must disconnect the USB cable from the computer, delete all drivers connected to local ports from the?Printers?folder, and then reconnect the USB cable to the computer. You should then receive a Plug and Play event for the product.Use the following steps to create the print path from the computer to the HP LaserJet product.From the?Welcome to the Found New Hardware?Wizard screen, select?No, not this time?and then click the?Next?button.Figure?: Welcome to the Found New Hardware Wizard screenFrom the?Found New Hardware Wizard?screen, select?Install from a list or specific location (Advanced)?and then click the?Next?button.Figure?: Found New Hardware Wizard screenSelect?Don't search, I will choose the driver to install?and then click the?Next?button on the?Please choose your search and installation options?screen.Figure?: Please choose your search and installation options screenSelect?Printers?for the?Hardware Type?on the?Found New Hardware?Wizard screen and then click the?Next?button.Figure?: Found New Hardware Wizard screen.Select any HP LaserJet printer from the?Add Printer Wizard?screen and then click the?Nextbutton. It is not necessary to use the product-specific driver. The purpose of this step is to create a print path to the product and any HP LaserJet printer driver will work.Figure?: Add Printer Wizard screenClick the?Yes?button in the?Update Driver Warning?screen.Figure?: Add Printer Wizard screenRename the printer you are installing, on the?Name Your Printer?screen, to “Hewlett-Packard HP LaserJet USB Upgrade”. Use this exact spelling (with no space between “Packard” and “HP”) since this is the name for the Plug and Play port in recovery mode for all HP LaserJet’s. This will help identify the driver to use when selecting the print path to the product. Click the?Next?button.Figure?: Name Your Printer screen?? NOTE:Do not delete this print driver from the?Printers?folder. Once this port is created, it can be used as the print port anytime an HP LaserJet product needs to be recovered. On any future recovery, you only need to plug in the USB cable to the product and run the HP Easy Upgrade Utility with this port selected to recover a product.While the installation completes, the?Completing the Found New Hardware?Wizard screen appears. Click Finish to close the wizard.Figure?: Completing the Found New Hardware Wizard screenA bubble message from the task bar will display:?New hardware is installed and ready to use.

Press the?Send Firmware?button.Figure?: Update Utility Builder tool screen?? WARNING:Only the formatter firmware is updated when the product is in recovery mode. Other components that have updateable firmware are not updated during this procedure. After the product is recovered, you must resend the complete firmware bundle to the product. This is necessary to avoid a mismatch between the formatter firmware and the other components in the product. It is important that the latest supported firmware bundle is sent to the product after the product is in a “READY” state.Firmware bundles are consumed by the product serially. Components are updated one at a time. The display will alternate between?Receiving Upgrade?and?Performing Upgrade. Once all components have processed the corresponding update, the product will reboot.Because the current firmware bundle is consumed serially, it may cause the Windows spooler to display a spooler text bubble stating that the print job has failed. This is normal and should be ignored. As the product updates a component, the Windows spooler may time out and display the text bubble. Once the next component in the firmware bundle starts to download to the product, the Windows spooler text bubble will close on its own. ................
