2.12.1 Two Tray Module II/III (PL17.2 ~ 3)

2.12.1.1 Main Functions
SWITCH ASSY SIZE (Tray 2) (PL17.2.7)
SWITCH ASSY SIZE (Tray 3) (PL17.2.7)
SWITCH ASSY SIZE detects the presence/absence of the tray and the
size of the paper.
SENSOR NO PAPER (Tray 2) (No Paper Sensor) (PL17.3.4)
SENSOR NO PAPER (Tray 3) (No Paper Sensor) (PL17.3.4)
Detects the presence/absence of paper inside the tray by change in the
actuator position.
(No paper: sensor blocked)
SOLENOID FEED (Tray 2) (PL17.3.17)
SOLENOID FEED (Tray 3) (PL17.3.17)
The ROLL FEED ASSY (PL17.3.3) motion (rotating/stopped) is controlled
by the GEAR FEED (PL17.3.11, PL17.3.12) rotation.
CLUCH ASSY TURN (Tray 2) (PL17.3.18)
CLUCH ASSY TURN (Tray 3) (PL17.3.18)
Driving force from the DRIVE ASSY MAIN (PL17.1.2) is transferred to the
ROLL ASSY TURN .
Operating Principles
ROLL ASSY FEED (Tray 2) (PL17.3.3)
ROLL ASSY FEED (Tray 3) (PL17.3.3)
When the SOLENOID FEED moves, force from the SPRING FEED
(PL17.3.9, PL17.3.10) causes the GEAR FEED and GEAR IDLER FEED
(PL4.3.14) to engage, the ROLL ASSY FEED begins rotating by receiving
driving force from the DRIVE ASSY FEEDER, and the ROLL ASSY
(PL17.3.25) feeds a sheet of paper from the tray. A notch in the GEAR
FEED causes the GEAR FEED and GEAR IDLER FEED to disengage
after one revolution, cutting the transfer of force and stopping rotation of
the ROLL ASSY FEED. In this way, one sheet of paper is fed at a time.
ROLL ASSY TURN (Tray 2) (PL17.3.20)
ROLL ASSY TURN (Tray 2) (PL17.3.20)
ROLL ASSY TURN begins turning by receiving driving force from DRIVE
ASSY FEEDER through CLUTCH ASSY TURN TRAY 1 and conveys the
paper fed from the tray to the Tray 1.
