I have a question regarding the theory of color laser printer operation.
Going through the service manuals of a few machines, I noticed two patterns (if I read correctly):
1. The toner is transferred directly from the drums to the paper (for instance - Brother MFC-L series).
2. The toner is transferred to the belt and from the belt to the paper (for instance - Kyocera M6035, Lexmark cs720de)
What are the pros and cons of each method? does it affect the print quality and amount of toner waste?

all of your questions are explained in the manual

Not quite true i.e. MFC-L9570CDW uses transfer belt.
Generally speaking most(if not any) modern A3 devices use belt system. Especially color devices because it allows much more precise color quality and color registration control thus high quality.
But transfer belt requires some physical space and cost. You cannot put it in small cheap A4 device

Yes, it does have a belt, but look a the paper path from the service manual:

And the description of the belt (p. 2-9): "Feed the paper to the drum unit and transfer toner on the paper. "
it is done on the transfer belt that MOVES the paper.
Correct brother. Again due to small footprint of A4 devices and depending on design sometimes there is no different way for paper sideways.

So is it really a transfer belt?
What did Brother gain from this method? After all, it forced such a convoluted paper path vs. using the belt for primary/secondary transfer?
with a color machine the color toners have different biases ... therefore a different charge is needed to transfer the toner from drum to page... the 4 rollers in the T belt provide the needed charge to do that.
here again that info is covered in the Service manual
The manual describes the how, not the why (the engineering compromises).
Yes it's transfer belt.
Besides you're asking some abstract questions neither of us can know answers. We are service engineers not design engineers nor accountants.
