Figure 13. Stacker/ASF Loop-back Connector. (Viewed From Right Side) If the loop-back connector is not installed, an error message will be displayed. To bypass this message, press the Micro ↓ key twice to advance to the next test. Display: T&D FRU 0[01] If an error message is displayed, go to "T&D Error Messages and Actions" on page 190. The test completed successfully if the display advances to the next test number. T&D11 - Pinch Roller Status/Sensor Tuning/Ribbon Feed and Lift Motors Note: Ensure there is no paper in any paper path. This test does the paper path sensor tuning but does not tune the tractor jam sensors, as these sensors are not adjustable. 1. The next display will be PINCH OPEN or PINCH CLOSE. PINCH XXXXX Note: XXXXX is CLOSE or OPEN. 2. The status of the platen pinch rollers stored in microcode must match the position of the rollers. Chapter 2. Diagnostics 168
