CAD printer question

[Tom Del Rosso]

I ask here because some of you probably have large format printers for CAD.
I have a new HP 7000 inkjet 11x17 inch printer, and it's noisy as hell
during and for some time after printing. I want to know if it's normal for
this model.

Thanks.

I have a Brother 11x17 all-in-one, which cost $350 a couple of years
ago, and works great for light duty use. I have it set up to scan via
ftp to my laptop or my office server.

Cheers

Anyone make a reasonably-priced 11 x 17 laser?

You can get a gently-used HP5000 series for about $400 on eBay.

Thanks. My "wife's" 11x17 deskjet is croaking ;-)

I have a HP Laserjet 4MV that is postscript and does letter / tabloid
(11x17"). Great workhorse. Quiet too.

What's reasonable? Last year's Lexmark 11 x 17 color was only about
$2,500 (a bit slow on the first page compared to the current model),
but the cartridges are not inexpensive. Great for schematics. They
mostly run around $3,500 and up.

Other than that, you're stuck with B&W or a cloggy inkjet. HP
Designjet roll-fed printers ("plotters") seem to be pretty good at not
clogging.

Tabloid lasers are big and heavy monsters.

Does it have ink tanks or just cartridges? Ink tanks are always noisy...

It has a modular design with a head assembly that is just an open-top box
with the heads on the bottom, and 4 cartridges snap into that box. The
cartridges mate tightly with the head assembly so it becomes virtually like
a single-piece cartridge.

Strong high frequency vibration could couple in widely varying degrees in
that situation, depending on the area in contact, rather than the firmness of
any point contact. (Minimising to point contact between parts might be the
best way to reduce noise). What you might try if there is room (and easy
access) is looking for slight curves on vertical corners on the catridges,
and pushing tapered matchsticks down the gap to reduce any wide area contact.
Even if you do it just once to test it you might figure out if it's worth
doing. I have no clear idea how precisely the plastics are formed so I can't
comment usefully beyond this.

The noise isn't HF vibration. It's mechanical noise. Even after printing
it continues to move the mechanism for an unusually long time even for an
inkjet.

If it wasn't for the fact that it prints successfully, I would think it had
a broken gear. That's the kind of noise it makes.

That's why I was hoping somebody might have an HP 7000 like it. There's no
other way to know if it's normal, depending on which I would either get a
replacement or a different brand.

Ok, so not directly from the head, maybe from stepper motors and belts.
Basically, if you can figure out which parts are involved, you might see
whether this might be influenced by small variations in mechanical tolerance.
If it is, there may be no such thing as 'notmal'. :) If it's down to the
drive parts there may be less variation so something to be gained from
comparisons. But first, see if you can apply figertip pressure gently but
firmly to parts of the innards while operating. if that's all it takes to
make big variations in sound, comparison with other printers will be far less
useful than testing locally and applying a spot fix.

Well, what matters is whether it's normal for the design to have that much
tolerance.

It's not very accessible when the lid is closed, but I did find some
"review" sites where people often found it a noisy model.

So I'll check other brands, as this is the only one in this size by HP.

Thanks for the input.

I had an HP plotter that was very noisy too. On slow moves it used rapidly
repeated pulses each hard enough to make a lot of noise. It amounted to
faster moves being more quiet because of smoothing by the inertia of the
parts. My HP Laserjet 5N is fairly quiet, but in another room so I don't hear
it so much anyway. (And no use to you, paper too small in this case).

Those people might be right, but if they didn't say what they had compared
with, I'd have no idea.

post a video on you-tube say "doues your hp make this horrible noise"
