Main Charge Grid

Each Imaging Unit includes a Main Charge Grid already installed as a component. Although the Main Charge Grid is not considered a consumable (because it typically does not wear out before replacing the entire Imaging Unit), you may need to replace it occasionally. It is recommended that you keep one on hand (order number 118-9070-02).

Illustrated instructions are shipped with each Main Charge Grid.

Use the print quality samples (page 7-13) to identify the symptoms of a worn Main Charge Grid.
