Troubleshooting a laser printer issue?

[scyto]

I have a brother MFC laser printer that random reboots.

It is plugged directly into a wall socket. I heard it reboot because it has a startup jingle.

Just before the jingle I hear one of my UPSs on the same circuit 'click'.

If the printer is off the UPS never clicks.

The GEM / Dashbox show spikes randomly for the circuit where the circutit goes from baseline of ~500 watts to ~800 watts. I see the same spike if i plug the printer in cold so i think these spike are symptom of the reboot, not the cause.

I am about to build case that brother need to replace printer - anything else i should think of that could cause reboots that the GEM might detect?

We have a a Brother DCP-L2540DW. It looks like it does the same thing when plugged in. The heater for the toner turns on temporarily likely.

Thanks, interestingly it had done this a few time since i purchased (i can look in the dashbox logs to see) but after powering off for a couple of hours it is now fine. Defintely something flaky.... i will see where i get with them
