And some of you may ask - why did they go from heating bulbs and aluminum to
flimsy films and ceramic elements? First they consume less power. Second
they can be made smaller. They heat faster from sleep mode. They are
obviously cheaper to make. They last longer in some sense, less time in
others. Generally the manufacturer makes more money in repair parts (fuser
assemblies) on these than they do on bigger models like the
5Si/8000/8100/8150. They do cost less per incident but more over time - 8150
goes 350,000 or better pages before replacement if a good rebuilder was
purchased from or from OEM, the film types go anywhere from 50k to 200k
dependant on the design and of course the parts used to rebuild.

I totally forgot - the 4200 is also latched in with two squeeze clips
where the 4000 had screws and the 4100 has levers - the latch on the gear
side (left as you look into the unit from the rear) has a tendancy to break
and then the fuser can travel and you get gear noise and sporatic
stop/starts of the film which causes damage over time too. I replace those
as well with aftermarket but it's not a total cure but it helps as they are
better made than HP's original and since HP doesn't sell these parts they
don't get my business on the parts.

This is what the film looks like, very thin seamless teflon tube that
slips over the ceramic element and housing. The element is a ceramic strip
with a resistance compound on it that locks into the diecast frame then the
film slips over that. This is the heater:
Class dismissed.

The 4000/4100/4200 line as well as the 2100/2200 and others like the
1100 and other smaller units even back to the 5L and 6L line use a ceramic
heater (as opposed to a halogen heater bulb) with a spinning teflon film
around that (as opposed to a non-stick coated aluminum roller tube) and on
some HP had a service note to replace fusers at their cost due to the film
guides being produced with a flaw that caused the film to ram hard into one
side and eventually shred apart. Other ones from the ignorance of the
untrained users will get twisted in half at the middle as they pull stuck
paper out incorrectly - they don't use the provided green wheel or the
release levers and therefore the paper in between the pressure roller (lower
roller) and the combination heater/frame and fuser fil, that replaced the
top roller is tight and pulling causes the film to spin on one half while
stopped on the other and it twists it apart.
I used to buy refurbished fusers, now I get rebuild kits for the
fusers at a much reduced cost. I do this on most HP fusers now,
film/ceramic and conventional heater bulb/tube roller types.
The 4200 and 4250 are another one with a chip, uses an antenna to
recieve/talk with the toner. If you pull the toner on the right side of the
toner at the edge that heads into the machine first you will see a copper
(brass looking) pad with a 3/8" blob of what looks like a melted plastic or
epoxy - that epoxy is covering the chip that dies when the toner goes empty
so that if refilled it still shows empty.
One thing that does cause "remove sealing tape", "toner low" or even a
lack of an image on the 42xx machines is a spring wire that stays in the
left groove to make contact with the toner's ground that doubles as a guid
pin on the left. The design of the 4000 and 4100 for the spring wire is
different than the 4200 and consequently the 4200/4250 is prone to the wire
getting out of it's place causing ground related mis-behaviors. Your Samsung
could have a similar problem but generally Samsungs have been pretty sturdy
machines even though not generally the mainstream brand for offices. The way
Hp is going they may one day be bottom line and others like lexmark,
Brother, Samsung. Okidata, etc be the normal thing in offices.

Well then, I'm the one who screwed up. I looked at reviews on line
and nothing came up about this. They had to have something bigger than this
Samsung. It has a three year same-day replacement warranty on it.
What do you mean "the films"? It runs nothing but plain paper
through it. Or is there something in it I don't know about.
They've had a couple of 22xx in there running like that for over two
years without a hitch. I also just put in a 24xx. I hope these hod up as
well.

They screwed up getting the 4250N, the fuser is notorious for
shredding the films.

It has a new cartridge. The company that had this wouldn't have
a clue about refills. They use a ton of paper/toner/ink etc. so they having
a purchasing company that handles all this for their supplies. This company
in turn makes arrangements and takes bids to get the best deal on stuff like
this, not just for one client but approximately a bunch. I suppose someone
could have slipped a refill to them, but I've never seen anything of this
nature happen before.
As long as this doesn't affect the printing, it doesn't make
that much difference to me. I hardly ever look at it anyway. They were
having a little trouble with it jamming, but I think that was because
someone was shoving some ragged-edged paper in it. This printer had about 15
people using it, and ran all day long. I replaced it with an HP 4250n. I
will say, this sucker really took a beating before I replaced it.

You think that's big? I have a Laserjet 8150DN I use here, it
sits on it's own cart. LOL
Anyway those have chips in the toner - is the toner a brand
new OEM fresh from the factory, or is it a rebuild or refill? That would
make the toner low error show as Samsung is going the way of others and
looking at making the big money on consumables - chipping them to make
refurb/refill toners a pain in the butt. No way to reset that, that I can
tell from any info I have on it. Now if it's a factory fresh new cart then
there is a problem. Some are done by electrical contacts, others with the
chip transmitting to a small antenna.
