S6
Paper Registration Sensor
This detects paper at the registration rollers.
S7
Paper Set Sensor
This detects when a cut sheet is placed on the manual
feed table (by-pass).
S8
Relay Sensor
This sensor is near the grip rollers, and (1) Detects the
leading edge of every cut sheet, switches off the
cassette paper feed clutch, and switches on the grip
rollers, (2) Detects paper jams where the paper feeds
out of the paper cassette.
S9
RF Exit Sensor
(1) Detects the leading edge of the paper from the
rolls.
(2) Detects the trailing edge of cut sheets from the
paper cassette and trailing edges of sheets cut from
the paper rolls for paper feed timing and jam
detection.
(3) If this sensor does not detect a leading edge after
feeding from Roll 1 or Roll 2, it also signals paper end
for the roll.
S10
RF Set Sensor
This detects if the spring-loaded lock lever of the roll
feeder drawer is locked.
S11
Roll End Sensor 1
This reflective photosensor above Roll 1 detects the
core of the roll (which is black), after there is no more
paper on Roll 1.
S12
Roll End Sensor 2
This reflective photosensor above Roll 2 detects the
core of the roll (which is black), after there is no more
paper on Roll 2.
S13
Roll End Sensor 3
Detects the trailing edge of the roll after there is no
more paper on Roll 1. This sensor is included because
if the color of the roll core is not black, Roll End Sensor
1 cannot always detect roll end.
S14
Roll End Sensor 4
Detects the trailing edge of the roll after there is no
more paper on Roll 2. This sensor is included because
if the color of the roll core is not black, Roll End Sensor
2 cannot always detect roll end.
