But what about, for example, a 3x4" photo on one page...
would it transfer to the "back" of the page above in the
I imagine that even my single-sided stack of paper will
cause at least some sticking just from the *weight* of the

Ah, OK. So it's just a "switch" in the software that
needs to be turned on (by the presence of a "magic bean" :< )

Excellent! Worth remembering! So, if I stumble across an
850, I should swap out the 840 (and/or 860??) in favor of it?

Yes. The LJ4M+ does similarly. The duplexer sits under the
printer and replaces the back paper path as well. As the
printed (first side) page is normally fed up to the output
tray, it is, instead, sent out a slot almost vertically.
When it seems like the paper is going to fall out on the
floor, it gets sucked back down in for the "verso" printing.

Presumably, if I find a *working* 850, it would be
preferable to keep in lieu of the 840?

I'll poke around inside and see if I find a spot for it...

I use the LJ4M+ for that -- it seems more economical (getting
a spare toner cartridge is relatively easy) and *feels* faster...
But, that's only B&W stuff.
