Overview
If you cannot open the drawer, follow this troubleshooting procedure.
Cause
- The drawer is in a “Not-withdrawable” state.
- 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.
- The pressure of the paper transfer belt unit is not released correctly.
- 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 paper transfer belt unit 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.
Solution (Detailed)
Step 1: Check the machine state.
Drawer Unit State List: Not withdrawable
Machine State | Solution | |
|---|---|---|
Output | Wait till the output has finished. | |
Correcting /Adjusting Operation | Warming-up, Process Control, MUSIC, Toner Recovery, Web Cleaning | |
Forced Power off | Forced shutdown due to blackout / disconnection, or pressing and holding the power button | Rebooting |
SC Issued | SC670 / SC672 occurs | See the SC table and follow the solution. |
DUB / TSB Abnormal | SC626 occurs | |
Defective Drawer Lock-related Parts | Cannot release the drawer lock correctly. SC525 occurs due to a problem with the drawer unit lock motor. | Go to Step 3 |
Straddling Jam | If there is a jam (such as the listed jams below) that straddles the drawer unit and another unit, the jammed paper will be torn if you pull out the drawer unit, and torn paper may remain in the machine. Jam between: The bypass unit and the registration unit The relay unit and the vertical transport The paper exit and the purge unit So in this machine, the drawer unit is locked when a straddling jam occurs. | Go to Step 2 |
Step 2: Check whether the pressure of the paper transfer belt unit is released correctly.
- Remove the Drawer Unit Lock Motor Cover.
- Check whether the D-cut surface of the end of the shaft points down.
If the D-cut surface direction is correct: Go to Step 4. - Release the pressure of the paper transfer belt unit by using the link plate. (If the Drawer is Locked)
If the Drawer Unit can be withdrawn: Solution procedure is finished.
If the Drawer Unit can’t be withdrawn: Go to Step 3
Step 3: Check whether the Drawer Unit Lock Sensor or Drawer Unit Lock Motor is defective.
- Do SP1-040-001(Drawer Lock Motor Unlocking Operation).
If the Drawer Unit is unlocked: Go to Step 4.
If the Drawer Unit is still locked: Go to Step 5.
Step 4: Check for the presence or absence of a straddling jam.
- Check whether there is jammed paper at the vertical transport, bypass unit, or purge unit.
If absent: Solution procedure is finished.
If present: Remove jammed paper. (Go to the next step.)
Step 5: Release the Drawer Unit lock by removing the parts related to the Drawer Unit lock.
- Turn the main switch OFF.
- Follow the procedure ‘If You Cannot Open the Drawer’ in the service manual, and release the Drawer Unit lock. (If the Drawer is Locked)
Turn the main switch ON.
If successful: Go to Step 6.
If an error occurs: Go to Step 7.
Step 6: Check whether the Drawer Unit Lock Sensor and Drawer Unit Lock Motor work correctly.
- Do SP5-803-204: Input Check Drawer Lock Sensor
- Do SP5-805-150: Output Check Drawer Lock Sensor
If successful: Solution procedure is finished.
If an error occurs: Go to Step 7.
Step 7: Check the connections of the Drawer Unit Lock Sensor and Drawer Unit Lock Motor
If the harness connection is correct: Replace the Drawer Unit Lock Sensor and/or Motor.
If the harness connection is poor: Connect it correctly. (Solution procedure is finished.)
