Table 8 Signal Names
Signal Name Description
/TG MCU 550 Sheet Feeder check signal which is transferred from the Print Engine
Controller PWB.
Signal Levels: High = 3.3V Low = 0V
FD TXD Control data which is transferred from the Print Engine Controller PWB
Signal Levels: High = 3.3V Low = 0V
FD RXD Received data from the Feeder
Signal Levels: High = 3.3V Low = 0V
/FEED 3 Feed control signal for the Feeder 3. The Feed Clutch Assembly and the
Turn Clutch Assembly are activated when this signal goes Low.
Signal Levels: High = 3.3V Low = 0V
/FEED 2 Feed control signal for the Feeder 2. The Feed Clutch Assembly and the
Turn Clutch Assembly are activated when this signal goes Low.
Signal Levels: High = 3.3V Low = 0V
/NO PAP 3 Signal from the No Paper 3 Sensor (equipped on the 550 Sheet Feeder
3). This signal is Low when the No Paper 3 Sensor is activated.
Signal Levels: High = 3.3V Low = 0V
/NO PAP 2 Signal from the No Paper 2 Sensor (equipped on the 550 Sheet Feeder
2). This signal is Low when the No Paper 2 Sensor is activated.
Signal Levels: High = 3.3V Low = 0V
/LOW PAP 3 Signal from the Low Paper Sensor 3 (equipped on the 550 Sheet Feeder
3). This signal is Low when the Low Paper Sensor 3 is activated.
Signal Levels: High = 3.3V Low = 0V
/LOW PAP 2 Signal from the Low Paper Sensor 2 (equipped on the 550 Sheet Feeder
2). This signal is Low when the Low Paper Sensor 2 is activated.
Signal Levels: High = 3.3V Low = 0V
/FEED 1 Feed control signal for the Feeder 1. The Feed Clutch Assembly and the
Turn Clutch Assembly are activated when this signal goes Low.
Signal Levels: High = 3.3V Low = 0V
/NO PAP 1 Signal from the No Paper 1 Sensor (equipped on the Feeder). This signal
is Low when the No Paper 1 Sensor is activated.
Signal Levels: High = 3.3V Low = 0V

Signal Name Description
/LOW PAP 1 Signal from the Low Paper Sensor (equipped on the Feeder). This signal
is Low when the Low Paper Sensor is activated.
Signal Levels: High = 3.3V Low = 0V
Print Engine Controller PWB <=> Size 1 PWB <=> Feeder PWB <=> Low Paper Sensor, Stack
Height Sensor, Feed Clutch Assembly, Turn Clutch Assembly and Motor Assembly
Table 9 shows the signal names for the Feeder PWB <=> Low Paper Sensor, Stack Height
Sensor, Feed Clutch Assembly, Turn Clutch Assembly and Motor Assembly path:
Signal Name Description
LOW PAP 1 Signal from the Low Paper Sensor. This signal is Low when the Low
Paper Sensor is activated.
Signal Levels: High = 3.3V Low = 0V
FEED 1 ON Control signal which actuates the Feed Clutch Assembly.
Signal Levels: High = 24V Low = 0V
/TRNC (OUT) Control signal which actuates the Turn Clutch Assembly. The Turn Clutch
Assembly is interlocked with the Feed Clutch Assembly.
Signal Levels: High = 24V Low = 0V
NUD MOTOR Control signal which turns on the motor Assembly.
Signal Levels: High = 3.3V Low = 0V
24V Interlock Interlock signal which related with the all clutches and motors equipped
on the Feeder PWB.
