 1. Download the file from the HP website. Rename the file P4015FW (do NOT change the .RFU extension) Copy the file into the root directory of drive C (when you click on “C” in the left column of Windows Explorer the file should be listed in the right column).

2. Open an “Elevated DOS Box” by clicking the “Start” button in Windows 7 and typing “cmd” in the search box. The letters cmd will appear at the top of the box next to a black square, right click the letters and select “run as administrator” and left click. A black box will open.

3. In the black box type “cd\”. The screen should now just have C:\ with a blinking cursor. Type ftp then space then the IP address of the printer (“ftp xxx.xxx.xxx.xxx” ) where the x’s are replaced with the IP address of the printer (for example ftp 192.168.1.46)

4. The printer will ask for a user name, just press enter 

5. The printer will ask for a password, just press enter again. 

6. Type “bin” (this sets the code to binary)
