Simply turn off the power, plug in the enabler, turn it on and now the MFP is print, scan, or print/scan enabled (depending on dongle) If you have the 2041 dongle, you must upgrade the firmware to 329 (I beilive) to allow the device to work properly. Now, if you know how to create a printer and can find the driver you should be printing. If you can't find the driver, at the RUN command, type
\\IPaddress of the MFP and press enter. Double click on one of the shared queues and go to town.
