Parts and diagrams: Internal assemblies
The gures below show component parts of the printer. A parts list table follows each gure, listing the item
number, the associated part number, and the description of each part. If a part is not listed in the tables, then
it is not a eld replacement unit (FRU).
CAUTION: Be sure to order the correct part. When looking for part numbers for electrical components, pay
careful attention to the voltage that is listed in the description column. Doing so will ensure that the part
number selected is for the correct model.
NOTE: The abbreviation “PCA” stands for “printed circuit-board assembly.” Components described as a PCA
might consist of a single circuit board or a circuit board plus other parts, such as cables and sensors.
