A table (material list) follows each exploded assembly diagram. Each table lists the reference designator, the associated part number for the item, and a description of the part. Parts that have no reference designator or part number are not field-replaceable units (FRUs) and cannot be ordered. While looking for a part number, pay careful attention to the voltage listed in the description column to make sure that the part number selected is for the correct product model. Replacing the printer engine assembly This table describes the components that can be transferred from a failed printer engine assembly to the replacement printer engine assembly. In addition to the components listed in this table, trays, CDROM drives, and power cords can also be reused. ENWW Accessories 285
