• Remedy: 1 Is the problem with Tray 2? Go to step 2. Go to step 7. 2 1. Pull out and then reseat Tray 2. 2. Does the lift motor operate? Go to step 3. Go to step 4. 3 1. Did the Error Code 87 clear from the front panel? Complete. This could be an intermittent problem. If the problem returns, replace in order: • tray level sensor • engine interface board Replace the engine control board. 4 1. Using Service Diagnostics test the tray 2 Sensors. 2. Does the level indicate H? Replace in order until resolved: • tray level sensor • No paper sensor • engine interface board • engine control board Go to step 5. 5 1. While still in diagnostics, pull out tray 2. 2. Does SW1-4: indicate LLLL? Replace in order until resolved: • paper-select switch assembly • engine interface board • engine control board Go to step 6 6 1. Reseat the paper tray. 2. Does SW1-4: indicate H in any position? Replace the paper feed motor. Replace in order until resolved: • paper-select switch assembly • engine interface board • engine control board 7 1. Pull out and then reseat the problem tray. 2. Listen for the motor, does the lift motor operate? Go to step 8. Go to step 9. 8 1. Did the Error Code 87 clear from the front panel? Complete. This could be an intermittent problem. If the problem returns, replace in order: • tray level sensor • engine interface board Replace the engine control board. 9 1. Using service diagnostics check the level sensor and no paper sensor. 2. Does the level indicate H? Replace in order until resolved: • tray level sensor • no paper sensor • LTA or HCF control board • engine interface board • engine control board Go to step 10. 10 1. While still in diagnostics, pull out tray 2. 2. Does SW(3,4,5)-4: indicate LLLL? Replace in order until resolved: • paper-select switch assembly • engine interface board • engine control board Go to step 11. 11 1. Reseat the paper tray. 2.
