• Description: BIN1 Tray Motor Error/Safety switch on - Finisher error - 1st-tray lift/lower motor (M107) This error occurs when the output bin 1 does not active the home-position sensor (PI116) when the output-bin-1-shift motor (M107) is drive for 20 seconds. NOTE: M107 moves both output bin 1 and the upper output bin that is attached to output bin 1 on the Stapler/Stacker finisher, but only output bin 1 on the Booklet Maker finisher. It also occurs when output bin 1 does not move when output-bin-1-shift motor (M107) is driven for 4 seconds. It also occurs when output-bin-1-switch (MSW103) is activated while output bin 1 is operating. NOTE: Output-bin-1 home position is detected using the top sheet of paper on the bin when paper is present and the edge of the bin itself when there is no paper on the bin.
• Remedy: 1. Manually release output bin 1, and then position it at the midpoint of its travel area. 2. On the product control panel, open the following menus: • Administration • Troubleshooting • Diagnostic Tests • Component Test 3. Test the output-bin-1.shift motor M107 using the finisher component test. 4. If output bin 1 moves during the test, continue with these steps. 5. If the paper-surface sensor flag was recently removed or replaced, make sure that it is installed correctly. NOTE: The four tabs under the clips must be inserted into the slots behind the roller shaft of the lower stack ejection roller. 6. Make sure that the paper-surface sensor flag is not damaged, moves freely, and is correctly aligned with the PI114 sensor body. Also, make sure that when the top edge of the output bin engages the sensor arm that the sensor flag moves into sensor PI114 7. Make sure that the sensor is securely fastened to the chassis. 8. Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris. 9. Make sure that intermediate connector J1040 and J7 on the stacker controller PCA are fully seated and not damaged. Check the wiring at the sensor. 10. If the error persists, replace sensor PI114. 11. If the error persists, replace the output-bin-1 assembly. NOTE: The output-bin-1 assembly includes the output-bin-1-shift motor (M1070), output-bin-1 switch (MSW103), output-bin-1 area sensors, and the output-bin-1 Area Sensor PCA. If output bin 1 does not move during the test, perform the following steps. 1. Check the output-bin tracks for damage. 2. Replace the output-bin-1 assembly. NOTE: NOTE: The output-bin-1 assembly includes the output-bin-1-shift motor (M1070), outputbin- 1 switch (MSW103), output-bin-1 area sensors, and the output-bin-1 Area Sensor PCA. Only if the error persists and none of the previous steps correct the problem, replace the stacker controller PCA.

• Description: BIN2 Tray Motor Error Finisher error – 2nd-tray lift/lower motor (M108) Occurs when the output-bin 2 does not activate the home-position sensor (PI115) when the outputbin- 1-shift motor (M108) is driven for 20 seconds. Also occurs when bin-2 upper limit is detected by PS983, PS982, PS981 on the Tray-2-Area Sensor PCA when no paper has been sensed by the output-bin-2 paper sensor (PI112). NOTE: Output-bin-2 home position is detected using the top sheet of paper on the bin when paper is present and the edge of the bin itself when there is no paper on the bin. Control-panel diagnostics: M108 tray 2 (output-bin 2 motor) and PI115 output-bin-2 paper-surface sensor
• Remedy: 1. Manually release output bin 2, and position it at the midpoint of its travel area. 2. Test the output-bin-2-shift motor M108 by using the finisher component test from the controlpanel display. • Administration • Troubleshooting • Diagnostic Tests • Component Test 3. IF output bin 2 moves during the test, perform the following steps. 4. Verify that the paper-surface sensor flag is not damaged, moves freely, and is correctly aligned with the PI115 sensor body. Also verify that when the top edge of the output bin engages the sensor arm that the sensor flag moves into sensor PI114. 5. Make sure that the sensor is securely fastened to the chassis 6. Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust and debris 7. Verify that intermediate connector J1040 and J8 on the stacker controller PCA are fully seated and not damaged. Check the wiring at the sensor. 8. If the error persist, replace sensor PI115 9. If the error persist, replace the output-bin-2 assembly.. NOTE: The output-bin-2 assembly includes the output-bin-2-shift motor (M108), output-bin-2 area sensors, and the output-bin-2 Area Sensor PCA. 10. If output bin 2 does not move during the test, perform the following steps. 11. Check the output-bin tracks for damage. 12. Replace the output-bin-2 assembly. NOTE: The output-bin-2 assembly includes the output-bin-2-shift motor (M108), output-bin-2 area sensors, and the output-bin-2 Area Sensor PCA. 13. ONLYl if the error persists and none of the previous steps correct the problem, replace the stacker controller PCA.
