Hi,

My problem started with the printer started to print blank at top of the A4 pages. This was a result of black developer leaking and falling down to the laserunit glass blocking the laser.
I have installed a new black drum and cleaned the laserunit and inside of printer from developer. After that it printed OK for a few hundred prints but now i have the same problem again. Developer everywhere wich have leaked down to the laserunit and blocking the laser.
I think it is developer and not toner because it will stick to a magnetic screwdriver...

I cant understand where the developer is leaking from because there is some developer on the gears but it does not seem to be coming from inside of the gears.
Could you please help me understand what is wrong. If i need a new developer or is the leak because of someting else?

I have attached pictures of the situation.

Appreciate the help.
