HPj5780 'all-n-one print/scan/fax/copy' won't scan

Just bought new HP Pavillion 1740n w/ Vista Home Premium. I am trying to add
a new HP j5780 'all-in-one' print/scan/fax/copy machine. All went well after
downloading patch? from HP site for Vista except for scan abilty. The j5780
says "scan options offline" refer to manual ( which was not in box).

Anyone know anything?

You can download a manual (User Guide) from the HP website at:

Re: HPj5780 'all-n-one print/scan/fax/copy' won't scan

I have spent most of the day with HP Tech Support and my problem is I have a
dual boot syetem where the XP version works fine and the Vista Ultimate won't
load the HP software for scanning. HP says my problem is because my copy of
Vista is not on the C: drive and this is where thier installer loads the
drivers, so skips this and uses Vista's HP drivers instead. Vista's only
supports WIA protocol and not Twain which HP software uses. HP says this is
NOT their fault and Vista needs to address the problem with their supplied
drivers. So onto Microsoft Tech support!!

Strange -- I'm dual booted XP & VISTA using the VISTA boot manager and when
I boot to XP it is on Drive C: but when I boot to VISTA it is on .... Drive
C: because that is the way the dual booting works.

This may be because I installed VISTA from a full version and did it by
booting up to the DVD, not from inside C:.

But although HP is correct in saying that WIA will not recognize TWAIN that
does not stop one from installing the HP TWAIN software and running it from
the HP applications (and in my case it also put a Scan To menu item in
Irfanview and in MS WORD XP.

You need to start from scratch in VISTA with it installing itself on an
empty drive or drive partition and allowing it to call that drive C:

Then you need it install the HP software without the HP hardware attached
and it seems best to do it using Run as Administrator (rightmouse click on
the file that starts installing the software, like setup.exe or the
filename that you downloaded if that is how you got the VISTA version.

It would be a good idea to go to the HP Download page for the J5780 at:


and get the latest VISTA fully featured software and the utility

HP Officejet Software And Driver Removal Utility

and use that first to clean up your VISTA installation, if you do not have
to reformat the drive and start again.

Do not connect the cable from the J5780 until the installation software
tells you to connect the cable to the PC or until you get to [Finish]

Hope that helps -- let me know if anything is not clear.

PS If you are talking to HP again tell them it is up to them to change
their software so that it does not insist on installing on Drive C: --
decent software gives you choices!

I did the same and my Vista drive also shows as C. But mine WAS an install
from inside the x64 version of Windows XP..... on to a clean partition of
course. That's the way Vista works, it will ALWAYS call it's root drive C:
when you are using Vista. So I'm not at all sure what the OP has actually
done, because whatever it is, shouldn't happen.

I don't know about 64bit ....

Have to see what OP replies .... and if he knows he has to install the
printer software under each OS if he wants to use it under both and not
just under one.

He can ignore what the HP support said -- they wrote the drivers for
"in the box" didn't they? <g>
