What happens when you initiate a scan from the Mac?


Why not upgrade to 10.5 or 10.6?  10.4 is officially unsupported by Apple and HP now.

I am employed by HP

Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Re: Photosmart c4280 error "usb not connected"

This message when you press the scan button means that the HP software is not installed or not working properly.


Check for a Hewlett-Packard folder in Applications.  If the folder is there, run the HP Uninstaller program. 


Now download the software package for Mac 10.4 from here:


When the software is downloaded, install it.

Here is a work around Smiley Happy


OK Folks, the HP software does not work with Snow Leopard.

f you use the Preview program from Apple it should work fine in preview to scan it to PDF or Jpg... at least it does for me. I couldn't save it at first and selected it and opened pages and then chose the save function from preview and it worked fine. There are hundreds of postings about this problem on other tech forums, It's a Shame the HP people haven't figured out yet they have a problem...They of course already have our money and are making new scanners that work with Snow Leopard. I'll be impressed if they fix this problem, it's been out there a while.
