Re: Turn off laser printer with power strip?

In a discussion as to why EEPROM is not used for storing real time
configuration, John Smith then cited an HP tech note that discusses
storing this data ... in NVRAM. Why would John cite this HP sheet in a
discussion of EEPROM? He did not know the difference between NVRAM and
EEPROM.

If you knew the difference, then why did you cite an HP tech note
that has no relevance? You did not understand that the HP tech note
had no relevance. You did not know the difference between EEPROM and
NVRAM.

Meantime, you have nerve. You constantly attack rather than ask
questions to first learn. You post as if you had engineering knowledge
which you even admit you do not. This engineer with decades of
experience repeatedly replies with technical facts that now cause you
to always post with insult. John Smith. I don't really care whether
you took insult. I owe you reams of insults - in spades. By your own
admission, you have no engineering knowledge. As a result, every
discussion we have had is because you were soundly wrong. And every
time, you don't even have the integrity to admit it.

Well, again, you are wrong. You posted an HP tech note about storing
data in NVRAM because you did not understand NVRAM was not EEPROM.
Admit it. You were again wrong. But you won't. I have caught you in
error too often. Your defense is to insult.

Don't be an ass. Those 'push in the rear' wire connections for wall
receptacles have often been problematic to electronics. Apparently
you are still too young - too wet behind the ears - to realize when you
don't know something. Sounds like your life ambition is to be a
politician. When a laser printer causes extreme brownouts, then
building wiring is a usual and first suspect. Power strips are
irrelevant. To someone so sure of yourself, that should have been
obvious. For others, John Smith does not even know about a common
problem created by 'push-in the rear' connections. So again, he
attacks as if that were technical proof.

John Smith wrote:
I neither wrote nor implied that EEPROM is the same as NVRAM, and I
challenge you to identify where I made such a claim. In fact, the reason I
posted the arlabs.com reference was so we could all see the difference
between the various devices. (Of course, some of us already were experts on
memory devices, as well as all other matters concerning electricity,
electronics, printers, and computers...)

This issue illustrates my criticism of your posts: You seem to read a few
sentences somebody else has written, think they were written specifically to
contradict you, then before reading the rest of the post and understanding
it you launch into a fresh tirade to tell us that you are the expert and
everybody else is wrong. Or maybe the problem is that you are not
expressing your thoughts clearly.

If wall receptacles are wired using rear 'push-in' connections, then Laser
printers may cause unacceptable problems - excessive brownouts. A
problem created when wire to each receptacle was not fully wrapped
around connecting screw (on receptacle side). Never use rear 'push-in'
connections on any circuit that has electronics.

To summarize, you allege:

1. Laser printers may cause excessive brownouts if they are connected to AC
receptacles which are wired with push-in connections.
2. The electrical problem with push-in connections is created when a wire
wrapped around the receptacle's screw terminal is not fully wrapped around
the screw.
3. Electrical outlets should never be wired with push-in connections if the
external circuit will be used to power an electronic device.

Rubbish. Sounds to me like junk science and an urban myth spread over the
Internet by people with little technical training. Please show us
references which support your claims and explain the underlying theory. I
never saw this type of warning on a receptacle or its instructions, and
surely the manufacturer would warn us of such important considerations.

Do not give us a long explanation of how a wire connected loosely to a screw
terminal increases electrical resistance, nor how the wire may be too short
to wrap securely around the screw or how insulation may be caught under the
screw head. We understand those potential terminal screw problems, but
those are not the issues you allege in your post. You allege a problematic
mechanical relationship between a receptacle's screw terminal and push-in
connectors and an incompatibility between push-in connectors and electronic
devices, specifically laser printers. Please advise.
