Bizhub 1050 pro developer drum removal

Does anyone know how to release the developer drum slider so I can clean and change the blades ? I have removed the screw that I thought holds it in, but it wont slide out. Is there a tab somewhere I'm missing ?

Thanks for any input

 

Page 38-41 of the service manual. Gotcha.

 

Your message does not say where you are at this point and there are several things to release/slide. Download a service manual it will help you great even if it will cost you $20, you're already saving $200-300 on service and will help you to resolve future issues.
