I have a Bizhub 4752 it is making a grinding sound when I print from the computer but when I do a straight copy it does make that sound. Please assist

SOURCE: Makes grinding sounds & usually prints blank

Changing the toer cartridge completely fixed the problem. I returned the defective genunie Bher toner. thak you!

SOURCE: Symptom: Grinding sound.

This could be either your drum cartridge or your fuser unit.

Take your toner cartridge out and look right up front where the drum cartridge empties 'waste toner' back into the toner cartridge.  There's a little flap there that slides back and forth on the very end.  Slide it back and see if toner is packed in there solid.  If so, vacuum it out.  Then you'll have to replace that drum.  Sometimes you can salvage them by cleaning out all the waste toner, but usually the gear in back has already stripped and it's no use.

If everything looks fine with the cartridges, it's probably the fuser.  You can buy a new one here:

The fuser is that part of the machine that gets real hot.  If you open the right side door, it'll be right close to the top.  There are usually 4 screws holding it in place.  If you take those screws out, you should be able to hold it away from the machine while it's running (you'll have to cheat the door).  If the grinding stops as soon as you pull the fuser away, that's probably your problem.

Let me know if any of this sounds too technical.  eric AT essonline.us

I would print out a copy of the network configuation of that printer and ensure it has the proper network settings (I.E. IP address, Subnet mask and Default Gateway. I just worked on a printer that I accidently pull the plug on and it lost it's network settings and wouldn't print until I changed them back to the correct settings.

Good luck

Look to see if the paper trays are set to the correct paper size. Also, look to see if the zoom is set to auto or at a 100%

Testimonial: "Thx! Unfortunately all those characters have already been checked, it seemes to be another kind of problem, any other thoughts?"

This is a fuser heat error. The fuser unit is located in the area where the paper exits the machine. It heats up and "fuses" the toner onto the paper. The error code means that it did not heat up properly. This means you will most likely need a service person to come out and diagnose the problem.
You can try to reset the error but I doubt it will help.
Turn off the MAIN power switch (not the one on the control panel)
Now hold down the utility key while turning on the main switch and continue holding the utility key for at least 10 seconds. You should see a screen come up with nothing but "trouble reset"
Touch trouble reset and you should see a small "ok" come on. Then turn off then on the main switch again.
Good Luck and Thank You for using Fixya.
