Re: 091-320

The rear side of the developer unit has a small metal plate that makes contact with a spring on the machine side. Remove the developer unit and clean that contact plate and the spring on the machine side (be careful - the spring contact can become dislodged).

Had this error code, tried the connectors and leads, tried a hvps. Turned out to be the A.C PWB...
