The printer was plugged into a surge suppressing power strip plugged into the same wall socket. It was this configuration causing the UPS to squawk when the printer was powered up or awakened for a print job. I moved the printer's power cord directly to the wall socket, but the UPS squawking continues.
I have seen this. Are you on AC 110 volts? I suppose you are. On 110 volt lines the current is double that what it is at 220 (230 now) as used in Europe. And the voltage drop when connecting another load is higher, because the resistance of the cables and connectors affect it more. Say, 10 amps, and a 1 ohm resistance, means a 10 volts drop. The UPS detects the voltage drop, and squawks. For an instant, I hope, then goes silent. Just ignore it :-) Mine, on occasion, triggers the battery for half a second now and then, on mains voltage drops that are not noticeable on the room lights. It scares me a bit, but I train myself to ignore them. :-} Maybe my neighbor connected his air condition equipment. Who knows...
I'm guessing what's probably going on here is the UPS is the problem. It's old, having been subjected to countless attacks here in the lightning capital of North America, yet its battery is relatively young. Either it's over-sensitive to voltage fluctuation from laser power-up, or the 5470 is drawing excessively, possibly explaining the big recent price drop for the model, which is at least one step above the bottom of Brother's laser printer line.
If the beeping stops within a second or two, ignore it. :-) - -- Cheers / Saludos, Carlos E. R.
