Novajet PROe Series Service Manual

Disconnect the Display Power Converter connector at the J10
location on the MPCB. To disconnect, grasp the Display Power
Converter connector between thumb and forefinger and pull
straight out.

To remove the Left Cover Assembly:

10. Open the reservoir access Door. Disconnect and remove all ink

reservoirs.

Figure 5-2. Left Cover Assembly Removal/Installation.

11. With a #2 Phillips screwdriver, remove the two screws securing

the Left Cover Assembly to the Left Baseplate and the two
screws securing it to the Left Sideplate. See Figure 5-2.

12. Reach under the Support Bracket and depress and hold the

retracting stop assembly that secures the Left Cover Assembly
to the Support Bracket.

13. Carefully lift the Left Cover Assembly up and off the printer.
