RAP 27 Paper Feed Brake Solenoid
Procedure
1. Measure the voltage at CNS, pin 1.
Voltage meaS"ree = +5vtx.
i :o tcl step 4.
2. Make a copy
The voltage at CNS-1 decreased to
approximately 0 VDC when the paper was
feeding.
i !eplace the main PWB (REP 8.1).
3. Ensure the solenoid actuator mechanism is
operating properly.
4. Measure the voltage at CNB, pin 2.
Voltage meas"res li/ +5voc.
I-
i f:eplace the main PWB (REP 8.1).
5. Disconnect CNS. Set the meter to meewre 64
ohms. Connect the meter across pins 1 and 2
of the disconnected connector CNS.
i
There is approximately 64 ohms present. 1

Go to Flags 1 and 2 and check for an
open connection. If OK, replace the
paper feed roller brake solenoid (P/O
Side Frame) (PL 7.1).
6. Go to Flag 1 and check for a short circuit. If
shorted replace the paper feed roller brake
solenoid (P/O Side Frame) (PL 7.1).
