- Procedure 3 –
When old developer cannot properly exit the development unit due to a clog in the
aperture, the amount of developer in the unit increases and could cause SC32x or SC39x
as a result of excess load on the development motor.
The goal of this procedure is to clean the aperture after removing old developer from the
dev unit to prevent SC32x and SC39x.
