I just bought a Photosmart C4680 with a new Mac Book Pro in September. The printing and copying functions work well, but everytime I try to scan I get a message "An unknown error occured" and the scan is cancelled by the software itself. If I try to scan again, I get a message that there is a communication problem with the scanner.. I have tried rebooting, shutting down, changing USB ports, uninstalling the software and reinstalling, nothing works. Any ideas?
This question was solved. View Solution.

Ich habe Heute ein Macbook mit Drucker HP C4680 gekauft.
Auch ich bekomme beim Scannen Fehlermeldungen und kann diese Funktion am Macbook nicht nutzen.
Ich hoffe es gibt eine Lösung dafür, da das Gerät ansonsten sehr gut ist.
Danke im Voraus für Hilfestellungen.

Not sure what the guy said in German, I hope this helps you as well. We've seen this mostly when there's a conflict between old and new software. Folks will automatically run the software off the CD when they are setting up a new printer. The problem is the CD is for 10.5, you didn't specifically mention what OS you are running, but you got the Mac in Sept, I am going to assume it's Snow Leopard.
Uninstalling by itself doesn't always resolve the issue, so there's a "scrubber" in the software that really cleans things out.
Go to Library/Applications/Hewlett Packard/ click on HP Uninstaller
Click on Continue
Highlight your device on the left pane
Hold the Ctrl, Opt and Apple keys and click on Uninstall
There will be a pop up that asks if you are sure you want to uninstall ALL hp software. (At this point, if you continue, any HP printers you have installed will need to be reinstalled, which is why we don't run this thing all the time)
Let the scrubber do it's thing.
After that, Add your C4680 through Print and Fax, and let the OS search for updates and such. If it asks you if you want to download them, accept.
That should take care of it.

I vhave the same problem exactly
What do you mean by add your printer through Print and Fax?
I am using a MacBook Pro, and have just uninstalled my C468 all in one Scanner/Copier/Printer using the above advice

OK, this worked!
Only I cannot scan using the controls on the printer itself, I have to scan through the printer software on my Mac.
But I guess that's OK.
For Tafandabay: Use the Apple icon on the op left hand side of your screen, then choose <System Preferences> <Print and Fax>, the software will guide you from there once you have uninstalled your printer.
Thanks for the help, saved me a lot of trouble!!!

All I did was uninstall everything according and then just go to Print and Fax, I did not try to add the printer myself.
I would make sure I don't have the HP installation CD in my Mac and that my printer is turned off.
Then I would follow the instructions for uninstalling (control_Alt_command-->OK) as in the solution message. Finally, use the Print & Fax option. When you go to Print and Fax the drivers should be downloaded and installed automatically.
I hope this helps.
