Paper Paths and Components
Dual Bin Structure
Schematic
The dual bin structure is molded in one piece to reduce feature to feature tolerance stack
up. It supports the whole weight of the primary paper path mechanism and writing system
from the top, provide mounting for the swivel PCA from the back, encapsulates the 100V
power supply on the right, and provides sliding surface and datum surface for the dual bin
tray at the middle. The x-y datum for the primary print mechanism on top is provided by
two datum pins at the structure and its z datum is given by the height of the dual bin
structure. The dual bin structure also provides datum pins for the swivel PCA and the
power supply. There are two bias springs which pushes the dual bin tray to the right
against the datum rail. This will determine the right margin for the media printed. Two
screw bosses which provides mounting location for the primary print units also serve as
the datum pins for the dual bin pick and feed mechanism, the dual bin pivot arm module,
which is mounted underneath the sheet metal dual bin beam top. The material
requirement for the dual bin structure has to meet grade V5 (Noryl) or better as it
encapsulates the high voltage power supply module.
