2.1.3 Function of Major Components
500 Sheet Universal CassetteUniversal paper cassette that holds 500
plain paper cut sheets of various re
g
ular
sizes. You adjust the Cassette Guides to
accommodatedifferentpapersizes.Adjustin
g
the Back Guide chan
g
es the position of the
Actuators that are located alon
g
the left side
of the cassette. When the cassette with paper
loaded is installed in the Feeder, the
Actuators press a
g
ainst the Size Sprin
g
.
Envelope/Postcard CassetteHolds standard envelopes and postcards.
See Section 16 500 Sheet Feeder
Specification.
PWB Assembly Size 500 A Sprin
g
CST Act, three Paper Size
Switches, and the No-Paper Sensor are
mounted on the Size PWB.
Spring CST Act: has three pron
g
s. The
Actuators on the side of the Paper Cassette
press a
g
ainst individual pron
g
s. Each pron
g
in turn press a
g
ainst a Paper Size Switch.
Paper Size Switches: A Size Switch is On
whenthe correspondin
g
sprin
g
pron
g
presses
a
g
ainst it, and Off when the correspondin
g
sprin
g
pron
g
does not press a
g
ainst it. The
combination of On and Off Size Switches
represents the size o the paper that is loaded
in the Cassette.
No Paper Sensor: When the Paper Cassette
is empty, the Actuator No Paper 500 actuates
the No Paper Sensor.
Sprin
g
CST Latch Secures the 500 Sheet Feeder in place in the
Feeder.
Solenoid Pick-Up Releases the Gear Feed to allow it to en
g
a
g
e
with the drive
g
ear and rotate one turn when
actuated, and latches the Feed Gear after
one turn. This causes the Roll Assembly
Feed to rotate one turn.
Roll Assembly Feed Is a D-shaped roll that is driven to rotate one
turn each time the Solenoid Pick Up is
actuated.
Roll Assembly Turn 2nd Transports, alon
g
with the Roll Pinch that is
located in the Cassette, paper out of the
Cassette into the Base En
g
ine paper path.

2.1.4 Paper Jam Detection
A paper jam between the 500 Sheet Feeder and the Sensor Pre-
re
g
istration (Misfeed jam) is detected usin
g
the E2-1 time. The E2-1 time
is a time interval from Solenoid Pick-Up actuation to Sensor Pre-
re
g
istration actuation. If the paper fed from the 500 Sheet Feeder do not
actuate the Sensor Pre-re
g
istration within this time interval, the MCU
interprets that a Misfeed jam has occurred and displays Error (Feed
jam).
The E2-1 time for the 500 Sheet Feeder (cassette 2) is 2.036 seconds.
