550-Sheet Feeder
The 550-Sheet Feeder increases the input capacity of the printer. The feeder attaches
below Tray 2 with four screws. When used in combination with the 1650-Sheet
Feeder, the 550-Sheet Feeder is installed between the printer and 1650-Sheet Feeder.
Up to four optional 550-Sheet Feeders per printer, totaling six universal trays (Trays
2~6), is allowed. However, when the 1650-Sheet Feeder (HCF) is installed, only one
additional 550-Sheet Feeder is allowed between the HCF and the printer. Electrical
connection to the printer is made by a single interface connector.
