Thanks "Guest", maybe I should call myself and bring my manual...Drum and dv were changed. I was looking for a real tech with experience on this unit, as I work on all models this being the only 350 I service. Thanks for the input...
Replace drum and developer every 120,000
copies. also al l3 sets of corona wires. clean the optics and run 2 simulations to set drum and developer
you will need a service manual and a technician
unless you know copiers...
Have you tried the drum. If it happens in regular intervals it could indicate a drum problem. Also i have seen loose charger wires cause this problem.
