When lock release solenoid [A] goes on, lock lever [B] opens.
- The lock lever on the left tray catches on the pin of the right tray, so only the left tray is caught and opens.
- With the lock release solenoid off, the tip of the lock lever catches and both trays catch and open together.
Normally, the left lock tray lock lever [A] catches pin [B] of the right tandem tray.
- If there is no paper in the left tray during printing, the right tray lock solenoid turns on to release the tray lock lever so the left and right trays can be separated.
- This allows the left tray to be pulled out to load more paper while paper is still feeding from the right tray.
