Install Capacitor Into Laser printer so it stops tripping the circuit breaker

I have a Brother L2360DW Laser printer. It commonly trips the circuit breaker when I print something. Laser printers require a spike of electricity when they first begin to print.

Apparently Brother sometimes doesn’t put large enough capacitors inside their printers to accommodate the required electrical spike and not end up spiking the house-wiring.

Does anyone know, does my printer have a DC converter just inside? If so, could I simply get a large capacitor of the appropriate voltage, and solder it onto the outputs of the DC converter to keep the printer from tripping the circuit breaker?

I think you're barking up the wrong tree.

What is the current and power rating of your printer?
What is the current limit on your breaker?
What other loads are on the same breaker?

The large current spike is likely due to the fuser heater in the printer which takes several seconds to heat up, so I don't think a capacitor will help that.
I've noticed that my lights actually dim slightly when that heater kicks in.

You can try putting the printer on a different circuit if one is available, if you already have the computer and/or other significant power drain on that outlet.
Otherwise you may need to check the breaker to see if it can be replaced with one that has a slow-blow or high-inrush delay characteristic.
You don't want to replace it with a higher current breaker since that would be against code and be a safety hazard.

Sounds like either a weak breaker or an already overloaded one that needs some of the load transferred to a different circuit.

Neither is a printer issue in my views.

Get a different printer and / or call in a qualified electrician. Don't try to modify the printer then take the chance of burning down your house. Mind you you want to modify it with what you have learned over the internet. :confused: The breaker is tripping for a reason. Either the breaker is bad or the printer is bad. Maybe it is a poor design? Still not worth burning your house down in an attempt to fix it.
