• Code: 373A
• Description: Tray 3 False Low Paper Level RAP Use this RAP when the machine displays ‘tray 3 is low on paper’ when the tray is full. The ‘tray is low on paper’ message should appear when the tray is at 10% of its capacity. The machine measures the time taken for the tray to elevate after being closed, to determine the amount of paper remaining in tray 3. This measurement only occurs if the tray has been open for a minimum of 30 seconds. If the tray is closed within 30 seconds the timeout of the last known paper level is used and no new timing is calculated. NOTE: A low paper condition will be declared if the stack is below approximately 190 sheets.
• Remedy: Pull out tray 3 and allow it to move fully down. Close the tray. The tray moves up. Y↓N→Perform the 373-100-00, 373-217-00 Tray 3 Elevator Lift Up Failure RAP. Pull out tray 3. Load a ream of paper (500 sheets). Wait for 30 seconds before closing the tray. The message ‘Tray is low on paper’ has cleared. Y↓N→Go to Flag 1. Check the tray 3 level encoder, Q73-340. Refer to: • GP 11 How to Check a Sensor. NOTE: In this check, use a piece of paper to actuate the sensor. The check is difficult due to the problem in moving the timing disc. •. • P/J755, IOT PWB. • 301E +5V and +5VSB Distribution RAP. • 301B 0V Distribution RAP. If necessary, install a new tray 3 elevator motor, PL 70.21 Item 1. If the fault persists, perform the OF7 IOT PWB Diagnostics RAP. The low paper sensor appears to be working correctly. If the customer is only adding small amounts of paper at a time, then the message ‘Tray is low on paper’ will be displayed. If the tray is filled with 190 sheets or more, the message is cancelled.
