    Konica Minolta Bizhub 554e Nasty Grinding noise.

    Hello,

    Just a little background on me. I am currently a Level 1 IT Technician. My skill set working with printers and copiers isn't the most in depth.I can change out rollers, fusers, ITB's, Drum units...basics maintenance stuff.

    So the issue I have with the konica is it makes a really loud grinding noise, it sounds like its coming from the area where the toners are installed. The issues started around the time I installed a new Image transfer belt.

    The prints do go through but the print quality is blurry. I also did notice inside the side door area; there is quite a bit of magenta toner residue. None of the gears or rollers seem stuck, and I have applied lubricant.

    Any troubleshooting tips?

    heres a video of the issue YouTube

    can you record and post the sound?
    toner can backup in the waste tube from the belt ruining the belt, easy clean though.
    why was the belt replaced? did it reach EOL or failed to clean itself.

    so many possibilities to speculate. i really think a recording audio or video may help some of us experienced techs.

    Well, NEVER EVER apply lubricant to anywhere near where toner is in a machine.
    Started in the copier service business in the fall of 1988 and worked at the same company for 33.5 years, becoming the senior tech in 2004 but left to pursue another career on 4/29/22.

    I did not apply lubricant to those gears.

    Sure thing. YouTube

    So i replaced it because it did reach its EOL, and prints had blotches.

    great vid!
    that sounds to me like the transfer belt waste auger gears skipping.
    when you open the front door and... hang on, ill get a diagram.
    ok, in blue is where i believe the noise to come from.
    the parts in red can be cleaned easily in place or removed.
    it's probably packed with toner.

    Great! Thank you for that information and Diagram. I will check out that area in red, and try to get it cleaned out!

    if you pull the transfer belt out by 6" there is only 1 screw to remove the chute and clean it out.
