I see a lot of service calls generated for this specific problem, unlike with the HP P3005 model where it’s kind of a secondary issue…“Oh yeah, and it seems to be running louder now then when we first purchased it.” I find than many users are afraid to continue to use the 2400 series because it sounds like parts are being destroyed. So identifying the problem in this model is easier and the fix is much more satisfying, because the printer is drastically quieter after it’s been repaired.
