5.2 Paper
Feeder
Since the Tray1 and Tray2 are functionally equivalent in terms of the Size Switch,
ACTUATOR NO PAPER, and SENSOR NO PAPER, only the components of one
tray are described here. Since the ACTUATOR LOW PAPER and SENSOR LOW
PAPER are not installed in the Tray1, the description of these components applies
to the Tray2 only.
150 FEEDER ASSY(Tray1) / 550 FEEDER ASSY(Tray2)
This is a mechanism for supplying paper from the Paper Cassette into the printer.
The driving force from the MAIN MOTOR is transmitted via the CLUTCH ASSY PH
to the ROLL ASSY FEED and ROLL ASSY NUDGER that are components of
FEEDER ASSY. Thus, the paper is transported. When the ROLL ASSY NUDGER
picks up some sheets of paper and the paper gets low, the position of the ROLL
ASSY NUDGER drops accordingly. The lowered ROLL ASSY NUDGER pushes
down the lock lever of the PLATE ASSY BTM, releasing it. The PLATE ASSY BTM
is pushed up by a spring, and thus the paper is raised. The raised paper then raises
the SUPPORT NUDGER. The SUPPORT NUDGER disengages from the lock
lever of the PLATE ASSY BTM. The PLATE ASSY BTM stops moving upward.
Size Switch
A switch for setting the size of paper supplied from each Paper Cassette is
mounted. A signal indicating the set size is transmitted as a voltage to the HVPS/
MCU.
ACTUATOR NO PAPER
If paper runs out in the Paper Cassette, the ACTUATOR NO PAPER drops and the
flag of the ACTUATOR NO PAPER that shielded the detection portion of the
SENSOR NO PAPEER moves off the detection portion. Thus, the light is
transmitted.
SENSOR NO PAPER
The presence or absence of paper in the Paper Cassette is detected by the position
of the ACTUATOR NO PAPER. This is converted into an electrical signal. If the
detection portion is shielded (i.e., there is paper), /NO-PAPER 1/2 SNR ON signal
is turned OFF.
SENSOR REGI
The paper transported from the Paper Cassette pushes up the ACTUATOR B. The
flag of the ACTUATOR A optically exposes the detection portion of the SENSOR
REGI. Thus, the passage of paper is detected.
CLUTCH REGI
This electromagnetic clutch turns ON and OFF the driving force to the ROLL REGI
RUBBER and ROLL REGI METAL, to place the paper in position.
ACTUATOR LOW PAPER
When paper is low in the Paper Cassette installed in the Tray2, the arm of the
ACTUATOR LOW PAPER is pushed up by the PLATE ASSY BTM. The flag of the
ACTUATOR LOW PAPER that shielded the detection portion of the SENSOR LOW
PAPER moves off the detection portion. Thus, the light is transmitted.
