Serial Nos. of the Affected Machines: Please refer to the following. Topic In a rare case, if the ribs of the joint gears contact each other when switching to the full-color mode (when engaging the gears), the worm gear might skip the teeth of its opposite gear Z due to the excessive loads applied to the developer drive gears engagement mechanism when the engagement operation momentarily stops, which might cause some abnormal noise. As the countermeasures, the shape of the joint gears was changed as follows in order to reduce the loads applied at gear engagement. Content of Changes The rib shapes at the engagement side of the joint gears ( X , Y ) of the drum/developer drive unit (DR-590B) were partly cut in order to avoid the contact with their surface. [DR-590B] (Unit circled in red line) DR-590B: Motor's side DR-590B: Gear's side Joint gears ( X and Y are inserted into the same shaft): By switching the gear Z by the worm gear when switching to full-color mode, the gear X is shifted to thrust direction to engage the gear Y or to release. (B/W mode: Gear X and Y released, Full-color mode: Gear engaged) Part the teeth skip (Teeth of the gear Z and the worm gear) Worm gear Gear Z (Above is the state of switching to the full-color mode)
