"Paper Size Mismatch" on HP C4480 - Argh!!!!!!!

[ExpoMarker]

I have an HP C4480 All-In-One printer. Scanning works, but when
I try to print, it gives me a "Paper Size Mismatch" error. I have
chosen different paper sizes (A4, etc), tried different OSes, and
tried different sized paper. Sometimes the printer works, but rarely.

This was not always the case. The printer is only about 6 months old,
and began having this problem 2 months ago. The ink is brand new, and
there's paper. The problem might be that the paper size sensor is
dirty or broken, and I read somewhere that I can physicall disable/remove
this.. or maybe in the software.

Please help!

I too am having the same issue with this printer... my printer is only 8 months old!  Did you ever resolve this problem?  I am thinking that I will have to take it in to be serviced..I have tried resetting all to default, (I am only trying to print on plain paper letter size) uninstalled, reinstalled, nothing works!
