The printer is brand new and was correctly installed using HP's instructions, and all the functions are working correctly, printing and scanning over WI-FI, scan quality and printing quality.
It is used on an i3 with 4gb ram and Windows 7.
My concern regards the scanning head. At 100DPI it's motion is continuous from one end to another, but when i set the DPI's over 200, then the head does like this :
- It moves for about 4 cm, then stopes ( the neon light also stopped), it moves back about 1 cm, and then it retakes the moving motion. This pattern is repeated a while until it reaches the end. The scanned file quality is not affected.
- Also when the printer powers on, the scanning head moves back and forward ~ 5-6 times for a distance of about 1 cm and then stops.
Any ideas, is this a normal behavior? My other HP F380 AIO and other scanners did the scanning in one full pass, without interruption, regardless of the DPI.

Yes this does sound as normal behouviour,
The movement at startup is a alignment, the scanner lights looks for a white strip that is in the inside of the scannerglas (out of our sight) to make sure it is in its start position.
The recurring movenment when scanning higher dpi is normal as well, the scanner will scan the paper more than once to ensure better results. The F380 had a differant technology so works differant.
