Q: My HP Photosmart 4480 its not scaning on my MAC OS X Mavericks 10.9.2

Hi..

There's an alternative for scanning when the printer / scanner model driver isn't available.

Launch Image Capture located in your Applications folder.

Connect the scanner to your Mac whether Wi-Fi or USB.

Click the very small black box bottom left side of the Image Capture window.

You'll see this pop up menu:   Connecting this (device) opens:

You can select a default app to scan (Image Capture) and select a folder from the Import To pop up menu on the right to save scanned files to.

If you need help with the Image Capture software, click Help from the Image Capture menu bar.
