If the product power is interrupted during the Erasing or Programming phase, the message ready 2
Download appears, and the Ready and Attention LEDs remain unlit after the product is powered back
on. On the computer, the update tool will not indicate that a failure occurred during the update. The
update tool will show that the download completed and might even have a yellow smiley face at the end
of the progress bar. This is due to the lack of two-way communication between the computer and the
product once the download begins.
1. Close the firmware update tool on the computer if it is still active on the screen, and then turn off
the product.
2. If the product is on a network, connect a USB cable (2 meters or less) from the product to an open
port on the computer. HP recommends that this be a direct connection instead of through a hub.
3. Turn on the product, and then wait for the message ready 2 Download to appear.
4. On the computer, cancel any alerts about a new device being connected.
5. On the computer, open the Printers and Faxes control panel.
6. Right-click the printer driver for the product model that is being updated, and then click
Properties.
7. In the Properties dialog box, click the Ports tab.
8. Note the name of the port that the product is currently connected to for use later when reconnecting
at the end of this process.
9. Click the check box next to USB001. If USB001 is already connected to another USB device, click
USBXXX where “XXX” is the highest-numbered USB device that has a description of “Virtual printer
port for USB”. Using the scroll bars on the right side of the window might be necessary, depending
on the number of devices installed.
10. Click OK to accept the change and apply the settings.
11. Restart the firmware update tool on the computer, and then select the same product that was just
created.
12. Start the firmware download.
13. Verify that the control panel display shows Erasing and then Programming, indicating that the
update process has begun. Do not interrupt the firmware update process.
14. The product should momentarily show the message Complete. Turn the product off and then back
on. The product will not automatically reboot.
15. When the product reboots, on the computer, cancel any alerts about a new device being connected.
16. Print a configuration page to verify that the update occurred.
17. Return to the Printers and Faxes dialog box, right-click the printer driver for the product model that
is being updated, and then click Properties.
18. In the Properties dialog box, click the Ports tab.
19. Click the check box next to the previous port to which the product was connected before the update
