Hey there,

I'd recommend visiting this link:

Ensure that you have the latest driver and firmware installed between your mac and the printer.

Hope this helps!

Hi,

i have installed the latest firmware (20120629) and i've tried to scan, but it doesn't work.

HPSCAN3 software trying to open a scanner session reply:

" Lo scanner ha rilevato un errore

Si è verificato un errore durante la comunicazione con lo scanner. "

The printer works fine.

Please, could you help me ?

Thanks before.

I figured it out.   I have a CM1415fnw and the scanner worked at first, then failed after a few days.

Ran the HP Print and Scan doctor and noticed the Printer had a different IP address than the Scanner.  Bingo.

Turns out the scanning software locks onto the current IP address of the printer at the time you install the software.  However in the real world most networks (corporate and home) tend to have variable addresses assigned by the Internet router or other DHCP server.  When the printer moved to a new address (at a minimum this happens if the router is reset) then software can no longer find the scanner.  Pretty dumb considering the printer-side of the software has no problem locating the printer; its doesn't lock onto an address.  Obviously the QA and Programmers on that side of HP need to do WAY better.

SO, solution....

1) Remove the current printer and scanner software/drivers/

     - Simplest way to do this is to run the HP installation program and select "uninstall" from the options

2.a) If you are a network admin in a corporate network, configure your DHCP server to provide the HP printer with a fixed IP address...somewhere high in your subnet is best

2.b) if you are a home user, log into your router through the browser interface, find the device configuration page, and tell it to reserve a fixed IP address for your printer, somewhere in the high range of your subnet (sorry, if you don't know how to do this you will need to read through your router manual or find the family member or friend who knows how to do this kind of stuff).

3) reboot your printer

4) reinstall your HP printer and scanner software

There.  Now that the printer won't move to a new address, the scanner software should have no problem locating and using it.

Really can't understand how the HP programmers did this or that HP QA missed it.  Pretty careless not testing in such a common real-world scenario.  HP recomending driver upgrades and firmware updates to fix these kind of problems is a bunch of nonsense.
