Please let the pictures provide the description. These boxes are still sealed. One box is labeled 3/18/19, the other box does not have a date. I do not know if age affects the performance of these items.One box is bigger than the other but both reflect the same part number. One box has some different WorkCentre model numbers listed, so presumably it is a newer version of the same item?I am not knowledgeable with these items as I acquired them from a surplus lot.Please confirm compatibility with your equipment based on the part numbers, pictures, and models listed prior to purchasing.Free shipping on this lot.
