One thing I really don't like about this, and really most HP printers
that I've used, is that it hates to print on the back of printed
sheets. Usually it eats/shreds about half the sheets one tries to
print this way. Yeah, I know, you can get HPs with "duplex" options,
but to me, that's utter bull****. I remember the old Panasonic laser
printer my old office had. It was a huge beast, and certainly no
better than the HP we also had at the time (LJ 4???), but the
Panasonic would feed *any* paper you put into it, even if it had just
been run through the printer on one side. I'd always use it to print
out my manuals on 2 sides for proofing.

It'll work better if you ensure that you print on the correct side of
the sheet first. Check your paper packet for an arrow, & a label
saying "Print this side first", & load your paper tray accordingly.
It'll also help to riffle the stack of paper before loading it into
the cartridge. Give the paper cartridge a shake to even up the edges
before putting it in the printer.

I've done all those things; none of them make the slightest difference.
(As a former printer, it's an automatic reflex for me to fan paper
before inserting it into a paper-eating machine.)

Well, something is clearly wrong. I serviced Canon-engine lasers for
many years, & all the larger models (ie; with more metal than plastic,
such as the CX, SX & MX engines) had really good paper-handling, & could
cope just fine with double-sided printing.

The old Apple LaserWriters with Canon engines are nearly unkillable, if
a bit slow. The most jam-prone printer I ever saw, though, had a Xerox
engine! You'd think that if anybody knew about paper handling, it'd be
them...
