Ad-hoc mode

This wireless environment involves a direct computer-to-printer connection. It does not require the use of an access point or wireless router serving as an access point. 

Before you begin 

  1. Make sure the printer is turned ON () and that the WiFi indicator light on the printer is ON .
    The WiFi connection light comes ON after the printer's WiFi card has finished initializing.
    NOTE:  If the WiFi indicator light is , press  to take the printer out of power saver mode. 

  2. Print the network settings page and verify the printer's factory default WiFi settings.  Click here for instructions. 

    • Settings of concern:  

    • Status - Not Connected

    • SSID - print server ######

    • Address -

    • Netmask -

    • Gateway -

    • UAA (MAC address) - 12-digit hexadecimal value

    • BSS Type - Ad hoc

    • If your settings do not resemble the above, it is recommended that you reset the printer. Click here for instructions. 

  3. Lastly, verify that the AirPort is turned ONHINT: Click on the AirPort status icon.    

Procedure:  Ad-hoc installation of the X4550 in OS X.4

) and then the  AirPort icon to perform this procedure.  
Be patient!  Your Mac may not immediately find the printer's Service Set Identifier (SSID). It may take a couple of minutes depending on interference, hardware performance, distance to printer, and wireless network traffic affecting bandwidth or throughput. 

  • Turn AirPort OFF and ON.

  • Turn the printer OFF and ON.

  • Verify that other wireless devices are being seen by the AirPort wireless adapter.



The AirPort status icon will change to reflect a direct connection between two wireless devices (computer-to-computer, computer-to-printer, and so on).
NOTE:  The image in the middle of the icon (see illustration to the right) is a computer.  This direct connection is commonly referred to as 'ad-hoc mode'.
