I have been playing with the various types of paper I can find
(coated, shiny, plastic foils etc). So far I have had the best luck
with an 80lb plain polished paper (it is quite shiny but no coating I
can detect). The combination that has worked the best is preheat the
board for 3 minutes and iron with gentle pressure (ie a little more
than the weight of the iron) for 30 seconds. The problem I am having
is getting the paper off when I have finished ironing. If I soak it
overnight I am fine but I would like to speed up the softening
process. Any suggestions? I was thinking of boiling water but I
suspect that will soften the toner to much. Are there any safe
chemicals that will soften the paper but not destroy the copper or my
kitchen?

My second question is if anybody knows of a way to get the printer to
deposit more toner. I am using an HP 1200 laserjet (which is great)
but I am getting better results if I run the paper through twice.
The problem with this is I don't always get perfect registration.

I use Dyna Art. The paper just floats off in mildly warm water after
ironing. IIRC, this paper is coated with a a layer of sugar, so that
might be the secret.

Perhaps you could experiment by spraying your paper with a solution of
sugar in water, and letting it dry before using it.

There is a way in my printer software (I have a Panasonic KXP-6500) to
specify greater toner density. I'd call HP printer support and ask
them if this is possible with your machine. The other option is to
look for denser toner. I understand it is made, apparently for use
in printing graphics, but I don't know where to look for it. There are
lots of toner supply companies on the net and elsewhere. Or perhaps a
copy house which also does laser printing could tell you.

I have quite a few blue-sheets that have PCB designs on them. They have
mistakes in the routes so I could not use them.
If someone would like a sheet or two let me know. This is a good way to get
your ironing skills down before you use a good sheet. Just use Lacquer
thinner to remove the traces and use the board again.
Or if someone knows how to remove the toner from the blue sheet without
hurting the sheet let me know.

How could this happen? I've got notices from other people complaining
about the same thing. How do I fix it? I've never had this problem before.

First off, let's take this off list.

2nd, get a virus checker. You should be running one.
My wife wasn't, her computer got infected without even
getting it by email, we think it was from someone's
website. 3 days after she started running without a
virus checker, Norton Antivirus reported more than
2000 infected files, none could be cleaned but only
quarantined. I ended up doing an FDisk, Format, and
Reinstall.

3rd, -don't- -open- -executable- -attachments-! Not
without scanning with a current virus checker first,
and even then if you weren't expecting it, don't open
it.

So many people tell me, "But I only open them if they
are from someone I know!" Well, duh, that is how the
virus propogates. It uses your list of email addresses
so you are SENDING IT TO PEOPLE YOU KNOW!!

4th, change your default settings in Windblows- set it
so you can see the three letter extension for -all-
filetypes. IE, turn off "hide extension for registered
file types". Note the name of the virus below- If
Windblows hides the ".scr" (script), then it looks
like an MP3. About the only things that can't hide
viruses these days are JPG, GIF, PNG, RTF, and TXT
files.

Please, last word on the list on viruses. Try the
newsgroup alt.comp.anti-virus and you'll get a lot
more experienced people.

http://groups.google.com/groups?hl=en&group=alt.comp.anti-virus

I use Norton AntiVirus from Symantec. You can download
a 30 day trial version.

Before you take it off list...

In addition to real live viruses, there are also a number of hoaxes doing
the rounds - email messages, again that you will receive from people you
know, with messages of the form "Go look on your hard disk for file named
XXX.YYY & if you find it, delete it & flush it out of your trash can. Then
send this message to everyone you know". The result, if you take it
seriously, is that you delete a perfectly good Windows utility file or
whatever, and tell your mates to do the same.

If you get messages like this, you can look up the encyclopedias held by
people like Symantec (who sell Norton Antivirus), Macafee, etc. and check
whether the warning is real or not before you a) damage your own system or
b) make a complete a$$ of yourself by sending the hoax on to your
mates/colleauges/clients etc.

I have had about 6 of these forwarded to me in the last year by people who
didn't know any better!

Regards,
Tony
