You haven't had to work on many of them, have you. ;) I worked on
paper feed systems (Ziyad feeders for Canon CX engine-based laser
printers, as well as the printers themselves) for several years when
those printers were en vogue.
That experience left me with the sincere hope that I never have to
work on another paper-handling device again, as well as the insistence
that any printer I own will be built to print all day, every day and
likely end up being a two-man lift. (which they both are, HP 8100DN and
8550DN)
Yes, paper feeding is, in fact, a feat. Yes, it is done all over the
place, and has been for many decades, but that doesn't make it any less
a feat, nor does it make it any less failure-prone. Document feeding in
particular is much harder, because (in comparison to printing) it
suddenly matters if you pick up two sheets at once, and you can often
bet that the paper is of less-than-straight-off-the-ream edge quality
