Hi tiffanyallen,


Have your new WiFi password handy and then follow these steps to enter your password.


  1. Press the SETUP button on your printer's control panel.
  2. Using the arrows, select DEVICE SETTINGS, press OK.
  3. Select LAN SETTINGS and press OK.
  4. Select Wireless LAN Setup and press OK.
  5. If a message appears to press the WPS button, press STOP to cancel.
  6. Select STANDARD SETUP from the next screen that appears and press OK.
  7. Highlight your access point or router and press OK.
  8. Press OK again to confirm the access point name.
  9. Enter your passphrase using the keypad to the right. 
    • At the screen where you enter your passphrase, in the top right corner of the LCD screen you should see a :1 .  This indicates that you are in numeric entry mode.  If you press the asterisk key (*) it will switch to :A or uppercase letter mode, pressing asterisk again with switch to lowercase letter mode.  To enter a letter in either letter mode, you will press the associated number key to cycle through the available letters.  For example: To enter a letter "c", you will press the "2" key three times.
  10. Press OK when done.
  11. The LCD screen will say "Connected" if the password is correct.
