Printer components and options
NOTE: When configured, each HCF tray can handle paper sized
from 7 by 10 inches / 178 by 254 mm to 17 by 14.33 inches / 432
by 364 mm. To feed papers smaller than 8 inches / 203.2 mm, an
optional 7 by 10 inch enablement kit must be installed. 17-inch/
432 mm paper can be fed only short edge first.
An elevator moves the tray up or down when it is in use. The
HCF trays have Paper Level switches which detect the position
of the elevator to determine the fullness of the tray. Paper Size
switches detect the size of the paper loaded in the trays.
The 4635 and 180 NPS/IPS printers can contain up to four high-
capacity stacker (HCS) bins as part of the feeder/stacker
modules (stacker bins A, B, C and D). The 96 NPS/IPS printer
can contain up to two high-capacity stacker (HCS) bins as part of
the feeder/stacker modules (stacker bins A and B).

Each HCS can hold 2500 sheets of 20 pound or 80 gsm paper
stacked on the bin platform.
NOTE: For large paper sizes such as 11 by 17 inches or A3,
there is a stack limit of about 1500 sheets. This limit is needed to
keep the total weight of the stack within safe limits for unloading
A stacking elevator maintains the paper at the proper level for
stacking and lowers the stack for unloading. There is an offset
mechanism that offsets printed sets toward the front or back of
the HCS bin. Each HCS bin has unlinked double doors to provide
you with easy, yet safe, access for unloading paper from the
