The 500-Sheet Paper Tray Option (Tray 2) Each 500-sheet paper tray option consists of: Ÿ    A paper tray support unit that attaches to the printer
Ÿ    A paper tray that holds the paper and is inserted into the support unit. This section describes how to install a paper tray support unit with a 500-sheet paper
tray and how to remove the support unit.   Because this option, when installed,
significantly increases the weight of the printer, consider installing the tray after other
options are installed. Acceptable paper sizes and weights for the 500-sheet paper trays are as follows: See “Loading Paper into the 500-Sheet Paper Tray (Tray 2)” on page  38 for
