I'm not sure whether the 5470 is actually working as it should. Each use causes the 900VA UPS plugged into the same 15A wall receptacle as the printer to squawk when the printer starts up.
Yes it will do that. My HL5170Dn does that!
Please do not connect it though your UPS. It puts a strain on the surge protection circuitry.
You seem to have misunderstood what I wrote: The UPS is plugging directly into the wall socket of a 15Amp circuit rarely used by anything except at this wall socket. Into the UPS are plugged cords for devices that are supported by and need to be on battery backup. Supported devices do not include laser printers. 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'd advise putting it on a separate dedicated surge protector power bar. I can't see a printer needing to be on the UPS. It might take out the UPS and take the computer/storage down!
I've never plugged a laser printer into a UPS under this roof, probably never anywhere. IIRC, I read the installation instructions on delivery of a HP LaserJet in 1984, long enough ago to remember. 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. -- "The wise are known for their understanding, and pleasant words are persuasive."
