I have installed Windows 7 and downloaded the HP drivers. My C6180 works fine except for one thing - it doesn't seem to recognise that the double sided printing attachment is installed. Any help would be appreciated.
I understand that printer duplexer is not getting recognised on you computer. Please try the following steps and check
Locate and right-click the printer icon for the HP Photosmart C6100 Series Printer . Click Properties . Click the Device Settings tab.. Click Installable Options to open it up. Click the drop-down beside Duplex Unit and choose Installed . Click OK .
Hope this helps.
