10 Beeps and Blinking Ready, Paper, Font and Pitch LEDs Tractor 2 home sensor never made after turning the printer off and then on, or made at the wrong time. (The same error indication is used for carrier home failure.) FRU Action 1 Tractor 2 Home Sensor Remove the Tractor 2 and turn the printer off and then on again to determine if the fault is in the printer or Tractor 2. 2 Main Logic Board If the gear teeth chatter just before the beeps, replace the home sensor. Remove Tractor 2 from the printer but leave the cable connected. Make sure the slider (the black plastic piece just above the right cover) moves after turning the printer off and then on. If the slider does not move after turning the printer off and then on: • Make sure the slider and gear train are properly connected and move freely with the power off. • Make sure the Tractor 2 board is receiving: +26 V dc on CN1-1 and + 5 V dc on CN1-5. If not, check the cable connection and the voltages at main logic board CN6-1. The upper right pin at CN6 is pin 1 (+26 V dc) and the pin just beneath it is pin 5 (+5 V dc). If these voltages are not present replace the main logic board. 3 Tractor 2 Motor Check the resistances of the Tractor 2 motor Board /Cable Asm windings: there should be 101 ± 5 ohms between pins: 1 and 5, 3 and 5, 2 and 6 and 4 and 6. If the motor is good, replace the board/cable assembly. For information on the Tractor 2 cable connectors, see "Tractor 2 Cable Connectors" on page 5-4. Diagnostic Information 2-41
