HP printer not seen

[Mayayana]

HP OfficeJet 7210 all-in-one. It was working
fine and suddenly just stopped. I tried to
reinstall the drivers, but it's just not seen,
by either the HP install or by XP plug'n'play.
I tried disconnecting and reconnecting the USB
cable. I tried using different USB ports. I tested
the ports with other hardware. As near as I
can tell, the connection through USB just
stopped happening. Does anyone have any
ideas? I've never seen such a thing. Can USB
cords "burn out"? Can the printer port somehow
fail, despite that the printer itself seems to be
working fine? (If the Print button on the printer
is used it will run a blank sheet of paper through.)

Out of ink?

I hear they have ways to punish people who are out of even one color.

Really? I thought you can configure your printer to print in B&W only
by default and so colour doesn't come in to the equation. I use HP
Laser Jet CP 2025 and I can ignore these error messages.

When ever there is any printer problem, one should just switch off the
computer and switch off the printer for about 30 minutes and then start
again and see if everything is reset after the cooling process.


With windows switching off and switching on within 30 d#seconds doesn't
work. I use DELL machines and sometimes even unplugging from the power
point, the machine doesn't switch off. You just have to allow some time
to cool it off.

Oops. I missed the words not seen.

Try another usb cable, another computer (laptops are good for things
like this), another printer in this port.

My Epson is like that. But this is not
failure to print. Windows is not seeing
the printer at all, and there are no error
messages from Windows or the printer.

What's the motherboard ?

The Intel ICH5/ICH5R can lose all the USB2
ports at once, via latchup. In extreme cases,
that Southbridge chip (no heatsink on top) has a
burn mark over the solder balls providing power
to the USB block.

Example - machine won't boot after the extreme failure case.

http://i.onfinite.com/TFG42bkgd.jpg

If there is no burn mark on top, then the only
lost, might be the function of all the USB ports.
With no burn mark, it might still boot.

*******

A second mechanism, is fuse failure to USB VBUS
on a particular socket pair. The Polyfuse is typically
green in color, and near the USB stack on the
computer motherboard. Move the USB cable to a
different socket pair, to test.

*******

Or, a problem on the printer end, checked by
plugging the printer into a known-good USB port
on another computer.

ESD can blow out USB ports, and if you noticed
a problem while scuffing over carpets in the house
(dry conditions), that might be enough to do it.
In the ICH5 case, the suspicion is, the latchup
is triggered by ESD.

The NEC USB2 chip (used on add-in cards), sometimes
loses a port or two, to ESD.

*******

I have had a problem with one USB port on my machine
here, where a particular USB Flash key and port combo,
are not detected. I suspect a problem with
something in the ENUM registry section. Moving
the USB key to another port, it works again.
Testing another device in the duff port, it
works too. Which is a pretty crazy failure.

There is a procedure available for clearing all
the USB section of ENUM. But if you use USB mouse/keyboard,
you could end up with a problem by doing that (mouse/keyboard
stop working).

A friends Epson went like that, not seen by the computer at all. He had
just replaced the colour ink cartridges so I removed and reinstalled
all of the cartridges and it started working perfectly and was then
seen.

Oops.. That's not the problem here, as I noted in my first post.

>Really? I thought you can configure your printer to print in B&W only

That's the kind of printer to buy, I'd say. I found a Brother, copier
scanner printer fax wifi makes 2-sided copies, in the grass next to the
street with a sign "Free" on it. and even though when I took the cyan
and magenta cartridges out, I could seel the ink sloshing around inside
them, when I plugged the thing on, the first thing that happened was
that the machine's little picture window said I needed those two inks,
and it wouldn't go any further.

That didnt' prove to me that it would work with more ink so I didn't
bother installign the software at that point, but I doubt it would have
let me get past this.

I tried to trick the printer into thinking there was print, held the
printer at an angle, even 90^, but I think it just stopped starting when
I did that.

I bought an OEM cartridge of magenta (about $10) and the magenta warning
went out, So I bought a replacement cartridge of cyan (about $4.75) and
now the thing works.

I talked to the guy who threw it away and he said it worked but he
bought a new one.

Interesting. I didn't know about that. This is
a Dell XPS 410, I think. But USB is working. I tried
the printer in 3 different USB ports. I then also
tried a card reader in one of those ports. All other
USB seems to be working.

We did have a thunderstorm the other day, thought
the computer was unplugged for that, so if the printer
was damaged it would have had to have been a surge
through the outlet. But then I wouldn't expect it to
all work fine *except* the USB connection.

I haven't had a chance to try another USB cord yet.
The current cord is 12', but it's worked fine for months
and the printer manual says up to 15' is OK.

Do you suppose it's possible that electronics involved
in the printer USB port itself could burn out somehow?

Weird. Thanks. It's easy enough to try that.

It could happen. It probably isn't
all that common. Software/firmware
is more likely to stop things from
working than hardware.

One repair technique is to "fully power cycle"
both pieces of equipment. Unplug each, give it
a minute or two to discharge. Then cable up
and retest. Just to cover the more exotic
possibilities.

I had a piece of equipment in the lab ($300 custom
chip), that went into latchup. I fired up the
prototype design, it went into latchup, and none
of the external pins would respond. I thought it
was dead, and went home at the end of the day,
not able to "revive" it by any means. When I left
for the day, I turned off the bench power supplies.

I came in the next morning, turned on the power, and
it worked! So then I had some inkling what the failure
type was ("latchup"). And I could set to work tracking
down the root cause. It turned out to be bus
contention (two chips driving a bus at the same
time), and the excessive current flow caused the
expensive custom chip to "freeze" all of its I/O.
The chip would not recover with a brief power
cycle. But the overnight wait with power removed,
allowed the phantom SCR circuits to clear (that's
what happens to CMOS in latchup, it's a phantom
SCR circuit that conducts current).

So you could say, I am a believer in occasionally
turning off the power, as a debug step :-) That
discovery that morning, saved me days of other
grief I didn't need. Problem was completely
fixed on the second day (mod to stop failures).

I know almost nothing about how these things work, but I can say that
several years ago a lightning strike next door burned out the parallel
port in my HP LaserJet 4100 (along with a couple other devices). I'm
able to use the USB port, and that's how I've been printing since then.

For what it's worth, the first USB cable I bought for the printer--an
expensive one--didn't work. I brought the printer back to the repair
shop, thinking something else was wrong; the tech guy plugged in another
cable. Bingo. It's been working ever since.

You remind me that about half or more of the usb cables I bought at the
dollar store didn't work. They had every kind and I wanted spares.

So far all the food has been edible, and all the drink drinkable, and
even the mechanical things mechanical, but the computer stuff only works
about half the time. Tha's when I call it the two dollar store.

[Mayayana]

Thanks, everyone. I tried unplugging the
printer before going to work, as per Paul's
tip. I just now plugged it in and Windows
saw it. Odd. But I had unplugged the computer
during a thunderstorm before the problem
happened, so I guess the two machines
somehow got out of sync.
