I purchased the printer two weeks ago. I'm unable to get the printers scanner and email buttons to connect to my computer...the program is HP OFFICEJET 6500 E70. I have spent hours and hours trying to

Your printer should still be under warranty.
Either take it back to the place where you purchased it or call HP. Their number should be in your manual.

Did you install the full software before connecting the all-in-one to the computer? If the printer not scanning to the local computer or a networked computer? Were you trying to use the scanner buttons?

If this is a local problem (USB connection) uninstall any generic driver (these only drive the printer) and then unplug the data cable. Next download and install the software from http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&lang=en&product=439491& (select your OS from the list). Connect data cable when prompted to do so. Try a new data cable if the problems persist (scanners require bidirectional communication and will fail when the printer works).
Try a direct connection (no USB hub or print server).

If the computer failed to respond to scanner button press, make sure that the monitoring program is running. You also need to set up the scan destinations in the HP Solution Center for the buttons to work.

If the scanner program isn't running, you can launch them manually. Computer > Local Disc (C:) > Program Files > HP > Digital Imaging > Bin (double click on each of the above drives/folders). Find either Hpiscnapp.exe or Hpqscnvw.exe and double click to launch the HP scan program.

XP, Vista and Win7 can acquire scans without the HP software but the scanner buttons will not work. All three can acquire scans with Paint (File > Import from Scanner or Camera > New Scan). Vista and Win7 also have Windows Fax and Scan (New Scan).

Since you need to set the destinations, you should use the HP software to launch scans first. This lets you get a feel for the defaults that will be best to put into the destinations.

I hope this helps.

Hi and thank you for using fixya:

I would recommend trying one of the followings:

1- install a fresh copy of your printer/scanner drivers.

2- check your firewall program it might be restricting the scanner software .

3- check the connection between the scanner and the computer

Good luck

You probably need a new printer.

You should have received a CD with the printer. I would go into the Windows Control Panel > Add/Remove Programs and uninstall the drivers for this printer (if they were installed when you bought the printer). Next, insert the CD that came with the printer and install the necessary drivers and software. After a successful installation, you should not be promted for the "msi" file.

I found a solution to this...

1. Go to the Windows Start Button
2. Click on Programs
3. Click on Windows Fax and Scan
4. Use that program to scan documents

Had exact same problem. Went to HP site and they said to check "add or remove programs" functions (in control panel) and if there are multiple copies of HP software to download their fix. I checked, had multiple copies, downloaded patch and all worked well again.

try opening the scanner from the START-ALL PROGRAMS-HP-ALL IN ONE

Click on the Vista Start Button
Click on All Programs
Select Windows Photo Gallery
Click on File
Select Import from Scanner
Import
Scan

'Twain' only means 'Technology without an important name', as this is refering to your printer/scanner, i would suggest that you disconnect the printer and remove any driver from Add/Remove programmes. Re-install printer software/driver and re connect printer when prompted and if possible in a different usb port, if that's how it's connected. If the problem persists and the pc is unable to communicate with the printer the fault will lie with the hardware. Hope it's only a driver glitch.
