Drawer Unit Lock Motor Emergency
Overview
If you cannot open the drawer, follow this troubleshooting procedure.
Cause
1. The drawer is in a "Not-withdrawable" state.
2. There is a paper jam between the Drawer Unit and another unit (this is called a 'straddling
jam'). In this case, the Drawer Unit is locked because if the user pulls out the drawer under
that condition, it would tear the paper.
3. The pressure of the PTR is not released correctly.
4. The Drawer Unit Lock Sensor or Drawer Unit Lock Motor is defective.
Solution (Summary)
Step 1: Check the machine state.
Step 2: Check whether the pressure of the PTR is released correctly.
Step 3: Check whether the Drawer Unit Lock Sensor or Drawer Unit Lock Motor is defective.
Step 4: Check for the presence or absence of a straddling jam.
Step 5: Release the Drawer Unit lock by removing the parts related to the Drawer Unit lock.
Step 6: Check whether the Drawer Unit Lock Sensor and Drawer Unit Lock Motor work correctly.
Step 7: Check the connections of the Drawer Unit Lock Sensor and Drawer Unit Lock Motor.
