HP Paper feed problem

[Helpmeplease]

Hi All,

I have a HP 3110 Multi function.

The printer is about 6 months old, for the last 3 months the paper feeder sometimes work and sometimes doesnt.

Sometimes when I press print it tries to capture the paper (i can hear it trying) and it says "printer is out of paper" and sometimes when I press print it captures the paper.

I would say 70% of the time it thinks the paper tray is empty.

The paper tray seems fine and the paper is always in-line. Im not sure why I experience this problem and would appreciate any tips.

Thanks

Print count? Good paper? Cheap paper? Evidence of paper dust built-up ?
