• Code: 373A
• Description: Tray 3 and Tray 4 False Low Paper Level RAP Use this RAP when the copier displays tray 3 or tray 4 is low on paper when the tray is full. The tray is low on paper message will appear when the tray capacity is at 10%. The machine measurers the time taken for the tray to elevate after being closed, to determine the amount of paper remaining in tray 3 or tray 4. 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 time-out 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 the relevant tray and allow it to move fully down. Close the tray. The tray moves up. Y↓N→Go to the relevant procedure: • 373-100-00 Tray 3 Elevator Lift Up Failure RAP. • 374-100-00 Tray 4 Elevator Lift Up Failure RAP. Pull out the relevant tray. Load a ream of paper (500 sheets). Wait for 30 seconds before closing the tray. The message, Tray is low on paper, has changed. Y↓N→For tray 3, go to Flag 1. Check the tray 3 level encoder, Q73-340. For tray 4, go to Flag 2. Check the tray 4 level encoder Q74-340. Refer to: • GP 11 How to Check a Sensor. NOTE: In this check, place a piece of paper between the sensor. The check is difficult due to the problem in moving the timing disc. •. • P/J2, HCF control PWB. • 301E +5V Distribution RAP. • 301B 0V Distribution RAP. Install new components as necessary. • Tray 3 elevator motor, PL 70.21 Item 1. • Tray 4 elevator motor, PL 70.21 Item 1. • HCF control PWB, PL 70.21 Item 2. 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.
