Diagnostic Information 2-61
4085-001
Paper feed pick assembly does not feed, paper feed pick motor
does not turn
Note: A noisy or chattering motor or a motor that fails to turn can be caused
by:
• A defective motor
• A bind in the paper feed mechanism
• Defective gears
• Defective engine board
• Defective power supply
FRU Action
1 Power Supply Check the power supply. See the “Power Supply
Service Check” on page 2-63 . If the power supply
voltage is incorrect, replace the power supply.
2 Engine Board Disconnect (J6) from the engine board. With the
power on, check the voltage between pins 6, 10,
and ground. The voltage at pin 6 should be
approximately +35 V dc. The voltage at pin 10
should be approximately +5 V dc. If either of these
readings are incorrect, replace the engine board.
Check continuity between (J2) on the RIP card
and (J14) on the engine board. If correct, replace
the engine board. If incorrect, go to step 3.
3 Paper Feed Pick
Motor
Index Motor
Disconnect (J6). Check between 6 and 7 on the
connector for approximately 27.8 ohms. If reading
is incorrect, replace the paper feed pick motor
assembly. If reading is correct, check the
continuity between each 6 and 7 to the motor
case. If continuity exists, replace the paper feed
pick motor assembly.
Check the index motor connector J16 pin 2 to
ground for approximately 27 volts. If voltage is
incorrect, replace the system board. If reading is
correct, check the continuity. See “Index Motor
Service Check” on page 2-56 . If symptom
remains, go to step 4.
Note: If a short exists in the paper feed motor,
damage to the engine board drivers and power
supply may occur.
4 Tray 1 Sensor
Check
See “Tray 1 Sensor Test” on page 3-27 . If test
fails, replace sensor.
