Jeez. Three responses from three "folks" and not one actually helped.

Jim, I have an HP3970 and there are 4 screws in the bottom corners.
I would guess that you should remove them as a start. Be careful as
much of the slide mechanism may be held in place by the bottom cover.

Michael, Why don't you cross-post all your responses to jerks, such as
Shephard, to something like "alt.ima-****ing-jerk", so we can filter
it all out ?:-)

Most well designed scanners have a method to address just this need.

You should be able to DL the manual from the HP site as well.

It should even appear intuitive. Well.... to some... ;-]

Usually, one of the ends has a cap that comes off, like the paper stop
end after removing part of the scanner apron or such.

The manual says:

For instructions on cleaning the underside of the scanner glass, go to
www.hp.com/support, select your country or region, navigate to the
support page for your scanner, then click the link to view information
about cleaning the underside of the glass.

So they at least promise to supply the information, and a support
request might be honored.

Here's info from a different HP scanner:
----------
If the 6200C is like the 6100C, which is mechanically similar
to my 4C ...
0. Disconnect power. Take anti-static precautions.
1. Remove the auto-feed assembly.
This should expose the rear Torx screwheads.
2. Remove the metal covers over the 2 front Torx screw heads.
3. Remove the screws and lift off the upper case w/glass.
4. Clean and replace.

Not surprising. They might still have some decent support people at HP
though unless they have laid them off and sent all the work to
Bangalore. Maybe they're afraid you'll cut yourself on the glass and
sue them.

If they had only supplied proper instructions on how to perform the

If you get impatient and you're feeling destructive
And... the scanner is slow and old and it's time to get a new one then
do this risky thing:
1) Put duct tape on the glass
2) Turn it upside down and smash the glass with hammer
3) Replace glass with something cut by a glass shop
4) Silicone the new glass in place..
Note: You could also devise a means to make the glass easy to remove
for future cleaning. (drop in frame..)
The fog up might return.

Where DO you come up with these stupid ideas? Do you have any idea
of what kind of glass is used in a scanner? Do you have any idea how
its mounted? Or how critical the thickness is?

Hee hee I make'm up for the entertainment factor..
If the scanner is for non-critical scans..then it might be ok..
Getting good scans of porno mags might be questionable.

But yeah...I don't know much about scanners.. It shows?

That has nothing to do with it, idiot. His stupidity lies in the duct
tape suggestion.

Glass might look green on edge, but a piece that thin is NOT going to
alter the color of a capture, so standard double strength glass would
surely work just fine, idiot.

Are you really so stupid as to think that duct tape would stop glass
shards from getting all over the inside of the device?

That is more retarded than your Intellectual Property theft spew was.

The duct tape helps but is not 100%.
That's why I suggested also turning the scanner upside down and then
cracking the glass enough such that it can be pulled away.

I did a very brief search for replacement glass.
http://www.anchoroptics.com/catalog/product.cfm?id=273

If you don't like the duct tape idea then how about this EVEN crazier
idea!!

Take a circular saw and cut off the entire top of the scanner.
Clean the glass and then glue the top back on.....

Anyone know how to dismantle and clean an hp3970?

I've developed a foggy looking coating on the _inside_ :-(

The manual says:

For instructions on cleaning the underside of the scanner glass, go to
www.hp.com/support, select your country or region, navigate to the
support page for your scanner, then click the link to view information
about cleaning the underside of the glass.

So they at least promise to supply the information, and a support
request might be honored.
All I find on the absolutely worthless hp site is instructions to
disconnect power before wiping the outer surface of the glass ;-)


You couldn't find this?

OK, idiot. Now find the instruction for cleaning the UNDERSIDE of the
glass.

You know... the dis-assembly procedure, and such...

I didn't see it, and I spent 15 minutes of my time looking for that
piece of **** Thompson's lazy ****tard ass. Now that I realize that he
is just as retarded as the TerrellTard, I won't give the ****head any
more of my time.

Liar. You can't keep from replying to ANYONE, and you know it.

I was unable to locate anything. Even the FAQ search for cleaning the
glass makes no mention of any surface other than the exposed surface.
Very lame, they are.

Never worked on HP scanners, but I've fixed Canons & various other
brands plenty of times, & the usual steps to dissasemble go something
like this:

* Hold lid by sides & lift until the supports pop out of the slots.

* Look for a retaining strip in the area that was covered by the hinge
of the lid.

* If present, unscrew / unclip to reveal one end of the glass lid.
CAREFULLY lift open end above case & slide out.
* Goto: CLEANING.

* Otherwise, place scanner upside down on SOFT SURFACE, grab a torch,
& look under unit for round screw slots or square/rectangular
retaining-clip slots. Remove screws or 'pop' clips with long,
flatblade screwdriver.

* If it uses clips, it's usually neccessary to apply a little tension
between the halves of the shell while 'popping' the clips/hooks to
keep them released. I use tongue-depressers or similar to keep the
halves from 'clicking' back together while I'm doing the other clips.

When the case is split, it should be easy to figure out how the cover
glass is being retained. Wearing clean gloves, remove glass
*CAREFULLY*.

CLEANING:

* Put on a pair of lint-free white cotton gloves, or a pair of clean
rubber gloves.
* Place glass on clean towel, folded several times.
* Spray Windex or similar ammonia-based glass cleaner on a clean lens
cloth or similar soft, *lint-free* cloth.
* Clean top side with damp cloth, dry with a *different* cloth.
* Flip glass, touching only the sides.
* Clean this side, as above.

* Slide glass slowly & carefully back into the case, in exactly the
reverse of the way you removed it. With some cases, it can be useful
to tie a ribbon or similar around the glass first, so you can support
it with your other hand, so it can't fall inside the case if you slip,
etc. Using your gloved finger, make sure the glass is seated solidly,
& flat, as it's not always obvious, & a bad fit will give you poorly
focussed/blurred scans.

* Without removing your gloves, reassemble the unit.

* Test. (Duh.)

That was what first came to my mind as well. I thought he was going to melt
the clips apart.
