This is an old Samsung ML-4500 printer, which was printing too light,

Yes you can swap the toner/drum around like you want to.
Wow. Somehow I was sure the answer would be no.
Unlike inkjet printers, laser printers use a dry powder that gets heated
in order for it to stick to the paper.
That I knew, but I still thought it was no.
However on some models it can get messy, that dry powder can get all
over the place if you are not careful. You want to keep the offline
toner/drum in something like a garbage bag until you need it again.
Try to keep the toner/drum in the same orientation as it is when it is
in the printer in order to help reduce the amount of spilled toner.
Okay.
Also some of the drums can be damaged if exposed to extreme light for
too long, possibly that is why all the new or refilled toner/drums I've
encountered are encased in a plastic bag that does not pass light. With
Yes, this new one is in a heavy black plastic bag, which I haven't
opened yet.
that in mind try to keep the offline toner/cartridge in a black plastic
bag rather than a clear one.
I save my clear bags for things I've bought and haven't used yet. When
I leave things I buy in solid color bags, I can't find them later.
I haven't done it lately, but on one occasion with a 35mm camera, it
was so cold out my fingers were almost numb and I cranked the crank
and ripped the film out of its little cartridge. I went into a
closet, put my coat around the camera, and put my arms up the sleeves
of the coat, to make it dark enough to open the camera and take the
film out. A couple other times I had to do something similar.
Thanks.
I'll try to upgrade to windows 8 before I do all this.
This is an example of a product, where the print cartridge
comes apart in two pieces. The drum can be replaced
separate from the toner.

"When replacing a photoconductor kit, do not leave the new
photoconductor kit exposed to direct light, especially sunlight,
for an extended period of time. Extended light exposure can cause
print quality problems."
"The photoconductor kit typically lasts for up to 30,000 letter-size pages
(at approximately 5% coverage)."
So that gives you some idea how long it lasts, if you don't
leave the drum lying in direct sunlight.
It would take me about 150 years to do 30,000 pages.
It doesn't mean going into the coat closet, and doing the surgery
under infrared light. Just use a reasonable amount of
haste when doing the work (no coffee break), then mount
the new toner in the printer, where the direct sunlight
cannot get at it.
Some toner cartridge designs with integrated drums, have
a shutter, and the shutter prevents scratches as well
So I had a reason for thinking that. That's good.
as reducing the light intensity seen by the drum. But
the shutter is far from light-tight, so you wouldn't
leave those inverted on a window-sill either.
Sure.
When you buy a refilled cartridge, you have no idea
what page count is already on the thing. Which is
why the prints could appear faded. It would take
No, I'm still using the original cartridge and the original drum. A
friend gave it to me, but I don't know how much he used it. I'm
almost certain the print used to be darker.
an ethical supplier who does test prints, to ensure
product quality before shipment. Just because the
drum is not scratched, doesn't mean it isn't worn out.
They should do some sort of test to prove it is in
good shape.
I think this is a new one, Samsung brand. I'll know more, maybe, when
I actually open the bag, but by then it will be too late to complain
to the vendor. Still it's probably fine. I've only been cheated a
small number of times, and never on ebay.
The idea of using the foil/plastic bag, is
for "bad storage situations", where the manufacturer
attempts to maintain product quality while in storage.
Like, a stockroom with direct sunlight exposure,
replacement carts left sitting on a shelf, that
sort of stuff. On a recycled cartridge, if they
use a foil/plastic bag, the drum could already
be worn out and faded, so the protective bag is
rather a joke at that point.
I hope it's new. Thanks.
Of course if it is new, I'll have to live longer than I planned.
