Another +1. Brother does make garbage printers in some cases, but their laser printers have been great.

I am curious about this myself am interested in bypassing their region and cartridge locks. It’s not that I want to use their printers, I just want to cause mischief.

Provided they don’t explode first, ceramic capacitors tend to fail short circuit. If you have a multimeter, do continuity checks across all of them. In-circuit capacitance testing is very inaccurate, so that specific test is almost always moot. Continuity testing may help.

Also, depending on the speed of the multimeter and the charge of the capacitor, it may briefly give you a tone and/or register as a short circuit. Capacitors can register as a short circuit very briefly until they get a slight charge.

The diode at the top right is another easy thing to check. (D12 // SS34) if it’s failed short, it will cause issues for you as well.

I am not sure what the component is that is under the heatsink by the USB connector. Sometimes, you may have voltage regulators stepping down the USB 5V to 3.3V. Those are easy to replace as well. However, if it is a USB controller of some kind, you would have to reference the datasheet and test it somehow.

Those are some simple checks you can do, anyway.

Doesn’t matter. Regardless of what Unity said their “Enterprise” plan was, it doesn’t matter.

B2B deals just work differently since both companies have more at stake. If a company like EA used Unity, there is no way Unity would want to lose that contract and EA couldn’t afford to drop Unity. Large companies will likely go through a few short renegotiation meetings, if that.

Plus, lawyers. If Unity even tries to force this on its larger customers, they are going to be hauled into court and most likely lose. When they lose, Unity will likely be liable for court costs as well.
