Bizhub 750 toner leaking n too solid

[brianho80]

Hi, does anyone know why this model always toner drop on T/S block and Mylar at drum unit full of toner.

I had tried to vacuum thoroughly the Mylar n path connect to filter behind machine, drum units etc..

Run this drum peculiar mode and even adjust max density adj = 19

But some how max density will change to 39 after exit to normal mode.

Anyone have other way to solve this problem?

This is a very well known problem on this model and there are many threads on this subject already.

If the waste section of the drum unit is full, this is usually a sign that the solenoid which drives the coils has failed, replace it.

As for the other causes, a simple search on this website will reveal all of the common fixes.

I don't know without my notebook, but their is a solution that has you change 2 dip switch settings that will reduce the amount of toner used. Also make sure your grid voltage is correct, especially if you use aftermarket drums.
