Hi Geoffrey,

Actually, the question you appear to want to ask is
"whose marking engine is used in Dell printers"
as any OEM probably still buys the marking engine
from someone else!

Considering the fact that DELL IS THE OEM, not the other way around.

Well, there can still be other OEM's upstream from Dell. E.g.,
they could be buying a marking engine integrated with some
smarts, possibly adding more of their own (or not) and then
rebadging it.

As far as sorting out what/whose *toner* to use/buy, I suspect
finding the marking engine manufacturer is where the OP wants to be.

(I doubt you could identify a toner manufacturer from a "genuine"
cartridge)

In computers, an OEM is someone who buys an item and slaps their name
on it.

In automobiles, it's the other way around because the US Congress screwed
that pooch too.

HP started out OEM'ing Canon laser printers, Apple OEM'ed the same printers,
with an added Adobe postscript board. This small development of a desktop
laser printer started a whole industry, and changed Canon from a successful
camera company to a very large office product company.

They still sell cameras, but it is a very small fraction of the size of
their office product divisions.
