# RIPS Unit Lower (WF-M5399 Series)

1. With the printer power ON, move the Lock Lever (A) in the direction of the arrow, and open the Ink Pack Cover (B).
   

   Check Point / チェックポイント

   In the next step, when securing the lever of the Cover Open Sensor with tape, secure it properly ensuring there is no peeling of the tape during adjustment. (If the tape peels, the “Cover open error” will occur and the adjustment process will be interrupted.) If Steps 2 and 3 are reversed, then sensor control within the printer will generate an “Ink cartridge not installed error”, and starting ink discharge work will not be possible.

2. Push the lever (A) of the Front Cover Open Sensor and secure it with tape (B).
   

3. Press to pull out the Ink Pack Tray BK (A), and confirm that the Panel LCD is in normal condition, and not in an error state such as a “Front cover open error”.
   

4. Connect the PC and printer using a USB cable and start the adjustment program, and from the adjustment program menu, select “Ink eject” and press the Perform button.
   

5. After finishing the Ink Discharge, disconnect the AC cable from the printer to turn the printer off.

   Check Point / チェックポイント

   Do not turn OFF the power by pressing the power button as that may cause ink to be re-charged. Since the amount of consumption of ink is not counted, take note of the amount of ink remaining in the Maintenance Box during Ink Discharge. If the printer has entered sleep state by the time Ink Discharge is executed, an “Ink cartridge not installed error” will be generated as a result of the sequence at recovery from sleep state. Lengthen the sleep setting time in advance.

6. Remove the Rear Unit (A) in the direction of the arrow while pressing the buttons inward.
   
7. Open the ASF Cover (A) and remove the two screws securing the Rear Housing Assy (B).
