They do not use the same engine. They are similar
(since they use the
same physical cartridge) but the way the operate is very different. The
CX laser printer engine uses a laser diode (I don't recall if it is

uses an incandescent lamp to illuminate a strip across the page as it is
scanned. The wavelength and amount of radiant energy involved are
completely different.
This is something I didn't though...Thanks for shedding a light on the
