228Parts and diagrams C9706-90926 How to use the parts lists and diagrams The figures in this chapter illustrate the major subassemblies in the printer and their component parts. 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 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 printer model.
