My guess is that someone thinks you can mix ammonia and various household

can't read the Hebrew warnings on the bottle cleaned their toilet with
ammonia and clorox and they had to evacuate the whole neighborhood.

Now the most exotic toilet cleaner you can buy is something called
"hot water" (may cham) which is a mild dilution of hydrochloric acid. So mild,
I don't think it will cause skin burns.

Geoff.

Actually, if you mix household ammonia and household tincture of
iodine you can produce trivial amounts nitrogen tri-iodide. Maybe
enough to break your skin. There are some other chemicals that can be
made as well. However due to the low active concentrations of
household chemicals the yield is extremely poor. More pigheaded
legislation.

I
have lost count of the number of them that I have drop-kicked down the

Well, do they grow there????

Indeed they do not. They rot gently away, which is the best thing that they

The trouble with them is, they are full of features, and cheap, so
every time I wear out an HP after 6 or 7 years, I get enticed into buying
another Epson, thinking that they can't still be in business by being
stupid
enough not to have finally sorted out the irretrievably clogged head
syndrome ... How wrong and stupid *I* continue to be :-\

Na, my oldest Epson is a Stylus Color 460, is older then your HPs,
works OK, apart from a bad contact in the chip socket that requires
re-inserting the big DIL chip every now and then, should
really fix this some time.
But it is noisy.
My Epson R200 is also many years old, end very very quiet.



I think then, that you have been very very lucky. Perhaps the ones you have
are so old that they come from a time when Epson could still build printers
that were not worthless junk, designed to gobble as much ink as they
possibly can, from every cartridge fitted, when the jets on the end of just

NTI is soluble in alcohol and perfectly stable as long as it's "wet".
An artist's paint brush and a classroom lock can generate loads of
fun. My senior year, I also had a master key to the interior locks in
the high school. That was fun too.

We kept it 'wet' by having it corked into the boiling tube as soon as it was
made. I don't know what the carrier liquid in Handy Andy was, but that was
what was keeping it wet. Whatever it was, quite volatile though, as it
didn't stay wet for long once a dollop had been splatted onto the floor.


How bizarre ! I too had a set of keys in my last year. At the end of the
previous year, we had a hot drinks machine installed in an open area under
our physics block, which was built on 'stilts'. By the side of the machine,
was a door which led to a cellar that backed onto the boiler room. The water
supply for the drinks machine came from in there. At the start of the autumn
term after the long summer holiday, myself and my little gang of
'troublemakers' - well, it seemed like we were at the time, but kindergarten
stuff compared to what you see in the papers and on TV now - were not far
away from the machine when the caretaker unlocked the door to go in and turn
on the water supply. He left the keys in the lock, and one of my 'merry men'
, who is now a senior pilot at one of the biggest airlines in the world,
crept up and removed the whole bunch. Afterward, he was terrified of being
caught with them, so he gave them to me for safe keeping. We had a lot of
fun that year, getting into places we shouldn't have been ...

I bet if I looked through all of my junk, I've still got them somewhere !

Here's a question. Is it because the Epsons that seem to prevail over long
periods, get only light use, as you say yours do, so only get turned on when
needed ? I think that this has a lot to do with the clogging problems of the
printers that Epson offer these days. I like to have my printer always on
and 'ready to roll'. I can't be doing with waiting 5 minutes while the thing
coughs and wheezes its way to being ready. When I need to print something
out, I need to do it now. The HPs seem to have a proper 'sleep' mode where
the heads 'park' over the seal, as it goes to sleep. The Epsons appear to
just 'stop' with the heads where they were last left. They only seem to park
if you do a full shutdown. IMHO, this is the reason that the heads clog.
Being left out in open space, the ink just dries in the nozzles. Once it has
done, it can take several cleaning cycles to recover them. The fact that
colours cannot be cleaned individually, is a royal pain in the arse, and
leads to huge ink wastage.

OTOH, my current HP is now probably 3+ years old, and has never been turned
off apart from the occasional need to do a full reset, when for some reason
the network has lost it, and it needs to be forced to talk to the router to
get a new IP address allocated.

To be fair to the Epsons that I have owned, I have never had an issue with
their general performance, speed, or print quality. I just find this head
clogging thing, which is a well known problem, sooooo frustrating, to the
point where I just get mad with them, which ain't good for the old
hypertension ...

If all you print is 5 times a week, and idle current matters that much,
burning a few calories by forcing anyone wanting to do a print job to
walk over and turn on the printer's main switch (zero idle current) and
wait a few minutes for the printer to boot up to its ready point would be
the right way to go.

Then again, it matters not what printer you buy, and you can plug it in
directly since you do not need "protection" for a device you only use 5
times a week, which has no need to be plugged into a UPS to begin with.
Any normal power strip would protect it, and many have RJ45 network
isolation ports as well. If you are using the USB interface, it IS 100%
plug and play and would not need to be plugged in until runtime either.

The power supply in the printer (or external on most of my inkjets) very happily
converts the output of a UPS to the DC that it needs.

The difference with laser printers is that the toner only sticks to the paper
as long as there is an electrical charge. To keep it falling off of the paper
after a few minutes, it has to be melted onto the paper.

The technical term used is "fused" and the part of the printer is called
a "fuser". They could of as easily called it "ironing" and an "iron", (as in
an iron-on T shirt pattern) but that would have been too simple and
not sound important enough. :-)

The problem with Epsons used to be that the print head stayed on the
printer, where HP replaces them with each cartridge.

That may have changed now though, since I haven't bought a printer in
years, and have seen several would be huge advances in detail and color
range capability. I don't know how they spray these days though, or who
the big print engine maker is, or if they all make their own now or what.

Used to be Canon. Seems like there are a lot of different "engines"
out there now though. Tektronix and Xerox still use solid ink methods.
I though most ink jet setups were piezo though by now, since it has such
precise fractional portioning ability.

The main power switch on the printer itself makes its off current zero.
You can build a small bluetooth device that fires a solenoid and a rod to
turn it on via network call if you want, and have someone else turn it

It was a Star Trek joke, actually.

No, it was actually used as a term to define the polymerization (the
actual term) of any polymer based media for many years.

Now, we know the term is 'polymerization' (with the exception of the
original definition for the term), so nobody knows much more about the
term 'vulcanization' beyond its original use, which most certainly was
for rubber, and required Sulfur.

So, it was loosely used to refer to the 'hardening' of just about
anything 'wet'. Not correctly, and not in large circles, but it was
used.

"Fixing" was a term that was already in place, and related to
paintings... works of art. That would have been the term until someone
cited the fact that at the microscopic level the pigment particles were
actually 'fusing' to the paper fibers.

Otherwise, everyone would call it a 'fixer' and the process would be
'fixing'.

Simply repeating the common pattern of the last few thousand years, I
think. The younger generation is *always* reckless and irresponsible,
hell-bent on disaster, and disrespectful of the wisdom of their elders
(from the POV of the elders), and the elders are conservative
hypocritical stick-in-the-muds who have forgotten how to live and who
are obviously guilty for completely yngvi'ing up the world (from the
POV of the younger set).

It's been that way at least since Aristotle, and probably a whole lot
longer than that.

OK then. Count me as well, i have an old Epson color 860 that still
works fine and an Epson R200 as my main printer. Of course i only use
them a little bit. Replaced the inks many times due to finally
running out.

Here's a question. Is it because the Epsons that seem to prevail over long
periods, get only light use, as you say yours do, so only get turned on when
needed ? I think that this has a lot to do with the clogging problems of the
printers that Epson offer these days. I like to have my printer always on
and 'ready to roll'. I can't be doing with waiting 5 minutes while the thing
coughs and wheezes its way to being ready. When I need to print something
out, I need to do it now. The HPs seem to have a proper 'sleep' mode where
the heads 'park' over the seal, as it goes to sleep. The Epsons appear to
just 'stop' with the heads where they were last left. They only seem to park
if you do a full shutdown. IMHO, this is the reason that the heads clog.
Being left out in open space, the ink just dries in the nozzles. Once it has
done, it can take several cleaning cycles to recover them. The fact that
colours cannot be cleaned individually, is a royal pain in the arse, and
leads to huge ink wastage.

OTOH, my current HP is now probably 3+ years old, and has never been turned
off apart from the occasional need to do a full reset, when for some reason
the network has lost it, and it needs to be forced to talk to the router to
get a new IP address allocated.

To be fair to the Epsons that I have owned, I have never had an issue with
their general performance, speed, or print quality. I just find this head
clogging thing, which is a well known problem, sooooo frustrating, to the
point where I just get mad with them, which ain't good for the old
hypertension ...

Arfa

Interesting. Both of mine are on continuously. And both park the
heads in sealed cups. Proper head parking is known to make a big
difference. Must be why printers that do not cap the heads combine
the print head into the ink cartridge.

Sorry, but I disagree. The US has been on a downhill path ever since it

So, how old are your Epsons ? None of the ones that I owned ever parked
properly. I wonder if they stopped doing it on later or cheaper models, for
some reason. OTOH, my HPs have all parked to a sealed area, yet some of them
have had the heads on the cartridge, and some haven't. The 5180 that I
currently use, has external heads, but they have never clogged as long as I
have owned it, so yes, correct parking is definitely significant in this.

Wont you have to open up the IEC power cord and clamp only a single

Nope. I have an adapter that came with a Radio Shock clamp on
Amps-guesser. 22-161 multiplier.
http://support.radioshack.com/support_meters/doc21/21584.htm
It's the device on the right. It's a double loop, with 10 turns in
one loop, and one turn in the other. With the clamp-on ammeter in the
10x loop, the current readings are 10 times larger, making low current
readings much easier. In the 1x loop, it effectively splits the line.
Very handy.

Incidentally, the clamp-on meter is a Honeytek A902 that I bought on
eBay many years ago. Not great, but it has the features I wanted. 2A
full scale, temperature probe, and peak hold. The peak hold is handy
for measuring laser printer inrush current, but I was more interested
in the peak current at a remote radio site, where transmitters are
constantly and randomly drawing current.

I also notice that many of these are powered with standard 10A IEC line
cords. How can that be right for a device with such high usage
declarations?

Dunno, but I can guess. Current capacity standards for device cords
are tested for maximum wire heating. While the 23A inrush current
might seem rather high, it only appears for perhaps a second, when the
fuser initially warms up. After that, the operating current of the
laserjet is well withing the current limitations of a common #14AWG
power cord. Try it. Does the cord get warm when furiously printing?
Probably not.

Well, I just tried it at home. 46A peak on startup for my HP LaserJet
2100 printer (at US standard 117VAC/60Hz). Ouch. I did it several
different ways and came up with roughly the same result. I couldn't
have done it without the "max hold" function on the Honeytek A902
clamp on ammeter because the inrush current doesn't last very long.
46A peak will certainly cause problems for any UPS running in backup
mode.
