Problem Vista 62-bit and Pixma IP 4500 persist

[A.Translator]

What type of power supply does the printer use? It's possible the

printer DC ground is floating, not common to the AC common or ground
outlet pin. If it's floating, it wouldn't be an issue of not having
grounded outlets, nor one of having the two pieces of equipment
plugged into different outlets.

What is a DC ground and what is a AC outlet pin? What is floating?

I am using "ordinary" two-pinned plugs in ordianry ungrounded sockets.

I don't think a clean install of Vista will help as the printer driver
was installed on a brandnew, clean desktop with a freshly installed
Vista.

According to Canon I am using the right driver for a 64-bit system.

For what it's worth I have a Canon scanner that does the same thing

on
Win2k.

Well, that is reassuring!

I have problems with a Canon Scanner 8400F too. With XP as well. I just
thought it was a loose contact for fiddling with the usb cable (without
unplugging it) sorts the problem.

What is a DC ground and what is a AC outlet pin?

DC ground is the ground level reference on typical computer and
peripheral devices, including the metal portion of USB plugs and
sockets' shells. If that doesn't explain it well enough, it is beyond
the scope of a usenet topic to review basic electronics design when
the internet is available and more thorough than a usenet post could
be.

AC outlet pin is simply the ac outlet in your wall, one of those holes
in it has a metal contact that could be referred to a number of ways,
including a pin.

What is floating?

AC ground is referenced (attempts to attain the same voltage level) as
earth ground, to have 0.0V difference between it and earth ground.
However with some devices there is no connection to earth ground, they
have what can be called a floating ground meaning their ground voltage
is independant of earth ground, may be positive or negative relative
to earth ground without it being a problem. Take for example a
battery powered radio. The negative terminal of the battery connects
to ground in that piece of equipment, but it is floating if there is
no electrical connection between it and earth ground, earth ground
really meaning "earth", soil, through water pipes or the wall outlets
in your home if they were properly wired.

I am using "ordinary" two-pinned plugs in ordianry ungrounded sockets.

Ok, but the most important thing you did not answer, what the supplies
for these devices are like. Do t hey use a 3 pin cord, and you have
outlets with the ground hole, or 3 pin and you have to use an adapter
to make them fit in your 2 pin outlet, or do they use only 2 pin
plugs? If they use 2 pin plugs, they aren't trying to by design,
don't need to ground themselves.

I don't think a clean install of Vista will help as the printer driver
was installed on a brandnew, clean desktop with a freshly installed
Vista.

You might be right, or the conclusion might be premature. It's also
possible there are patches that improve OS functions broken, or
patches that broke things which previously worked. The ultimate goal
is to leave no variables unexplored and the OS is certainly one of
those variables. If you only assume something can't be wrong, it can
waste a lot of time trying other things. Even so, you know better
than us what the state is of everything there, installing an OS and
reconfiguring it does take longer than other attempts so it makes
sense to try other things first.

According to Canon I am using the right driver for a 64-bit system.

Ok, but being the "right" driver doesn't necessarily mean there isn't
something wrong with that driver, if it has a design defect, a bug
interfering with it working properly. This is quite commonly the
case with the first few revisions of a driver for a new(er) OS, or a
new product on an old OS, upon which they didn't do enough testing.

unplugging it) sorts the problem.

If fiddling with the cable fixes it, you have a different problem as
that would not resolve the situation I am seeing with a 4400F, we've
tried multiple USB cables, multiple USB sockets including a separate
USB2 card, plugging & unplugging the scanner and/or power cycling the
scanner. When it disappears the only way to consistently revive it is
to reboot the system, no need then to turn it off or touch the
cabling. Since the 8400F and 4400F are somewhat similar, it is
possible you have both problems, or that in your case the loose
electrical connection is the equivalent of unplugging and replugging
the cable and that works in your situation against the same problem,
but not for me or others who have reported having the problem.

I should add that the same system and same USB cable works fine on a
2nd scanner right next to the 4400F, once I install the driver for it
and change which one is connected. Apparently, Win2k, and possibly XP
as well, will have problems if there is more than one USB2 scanner
connected simultaneously. I did not conclude this only from
observation but also from researching the matter on the internet
trying to find a solution for the 4400F.

I appreciate it is impossible for you to make an educated guess.
I am sorry, but what is the difference between sitching on the PC and
just switching on Windows again?

Maybe some weird h/w problem? Insted of Start->shutdown try
Start->restart. If you _have_ to wait several minutes before switching
the PC on, then maybe sth is wrong with your PC? Maybe something,
somewhere is overheating? Better let's not get down this route - too
many possibilities.

I will try that tomorrow ( it is late here).
Not much is connected to the pc though, just a broadband modem. No TV,

^^^^^^^^^^^^^^^^
Try to work without modem (disconnect it from your PC and see if it
changes things).

speakers, or other stuff. (well, as I type this, I realise, there is a
scanner, but that is not switched on).

Just for the sake of it try to disconnect it.

Thanks for your patience, Jerry.

I'm afraid I'm of no use here - the problem doesn't want to be solved ;-)

changes things).

I have tried that. No change, hélas.

Just for the sake of it try to disconnect it.

No change either....

I'm afraid I'm of no use here - the problem doesn't want to be solved
;-)

I am beginning to fear that to and am looking at giving this priner
away (I don't dare to ask money for it) and buying a different
non-Canon one. Stupid thing is, when the Canon does print, it is fast
and good.

I thought I had answered that, but the terminology sometimes goes over
my head. My devices have two-pinned plugs, so that would mean they are
not looking for grounding.

You might be right, or the conclusion might be premature

Yes, it might be premature, but I am stuck with Vista. Cannot buy XP
anymore and do not want / cannot use Linux etc. I have tried a Mac but
that was no succes. So Vista it is for me.

I am going to buy a new printer.

Thanks for your pateince and explanations.
