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...


My Xerox (a 5400) has been very good, about one jam every six months
(usually after loading the tray). Does reasonably on double sided, but
not perfect (I really would like to get the duplexer option, and am
watching eBay for one). I actually am picking up a second 5400 this
morning, too, for either spare or second use.
