Upgrade the firmware

Follow these steps to upgrade the firmware on the printer.

Note:

To upgrade the firmware, make sure the printer is connected to a PC running Windows OS.

The "HP_Laserjet_Pro_4000_Series_901.2225B.exe" firmware package is used for updating the firmware from Windows.

On your computer, download the firmware file (HP_Laserjet_Pro_4000_Series_901.2235B.exe) and save it to your hard drive.
Navigate to the folder where you saved the .exe file and double-click the file to start the upgrade.

Once the .exe package is executed, the firmware update software will search for printers connected to the PC via USB, or printers that are on the network.
When the HP Printer Update screen displays on the computer screen, select the check box(es) next to the printer(s) that you want to update, and then click Update.

The firmware update will begin.

While the firmware update is in progress, an "Updating" message will display on the printer control panel.

When the firmware update is complete, the printer will automatically shut down and turn on again and boot to a "Ready" state.
To verify that the printer firmware upgrade was successful, print another Printer Status Report (using the instructions in the previous section of this document) and check the Firmware Version listed on the report.

The firmware version should now be 901.2235B.
