E Studio 351C Disappearing developer

[yormets]

Does anyone know what makes the black developer just vanish over a few months from the unit. It doesn't throw any errors. There just simply isn't enough developer left in the unit. The copies start fading away. I've done all the calibrations normally done. Everything seems to be fine.

Developer depletion is usually associated with chargers arcing, Check charge & discharge. Dirty laser glass will also cause faded copies.

also check behind the developer unit as these have a habit of chewing seals and dumping the dev inside the machine.
