Question about HP LaserJet 3330 All-In-One Printer
Smeared output can result
when you re-feed a printed page into the
printer to make a double-sided page. This happens because the
rollers that grip the paper to pull it into the printer can pick
from the first side’s printing and smear it. So before replacing
parts, this is an easy thing to check. Printing multiple pages
will make the pages print progressively cleaner or you can clean the
rollers with rubbing alcohol.
Smeared toner also happens because the nonstick coating on the fusing roller is scratched or has baked-on debris. This can happen if the printer is in a dirty environment especially. If you are comfortable removing the fuser, you can try to clean it with a soft cloth and alcohol, but make sure you let it cool down first!
Finally, if this does not resolve your issue then make sure the fuser is heating; toner that is not heated properly will fall from the page and smear. If the thermostat is bad or the fuser not working properly, you will most likely need to replace the entire fuser assembly. This will be pretty expensive to repair so hopefully it's one of those other issues.
As for the noise, there are several complex gear and roller segments that drive the paper between the paper tray, the scanner, the fuser, and the finisher. If these are not perfectly aligned or dirty the printer can make a grinding noise. It's even possible that if the paper is not being fed correctly, that the shift might leave segments of it less accessible to the fuser and prevent the toner from adhering to the page.
But I would try using WD-40 to lubricate some of these components and assume the noise and the smearing are separate issues.
