I needed to update the firmware for Dell 1235cn. And so to do that I just used the tool for firmware update from Dell for uploading a suggested firmware update. The status window within the printer now has "Warming up Please wait". This is as it is from last one hour. I was associated throughout the network card and did not detach something or turned off something. Can you tell me that why this is showing me that message. Please reply as early as possible.
