Access internal components
This section describes how to open the PRISMAsync controller and gain access to the internal
components.
Procedure
1. Shutdown the System.
If the system is in sleep mode then touch the On/Off button to shutdown the system. If the
system is not in sleep-mode then touch the [System] tab followed by the [Setup] tab. In this
screen touch the
On/Off button. In the next screen touch [Shut down].
The system will shut down.
NOTE
Do not switch off the power button of the copier. It will switch off automatically.
You can also touch the
[Sleep]
button when the system is not in sleep mode.
2. Remove all cables from the back of the PRISMAsync controller.
If you have wrapped the cables then release the tie-wrap.
3. Remove the left side cover of the PRISMAsync controller.
To remove the side cover, remove the 3 screws at the right side on the back of the PRISMAsync
controller. Then shift the cover to the back to let it come off.
4. Open the cable ties attached to the middle bracket.
These ties are re-usable and are meant for keeping the cable bundles in place and to avoid them
from making contact with the fan.
5. Loosen the 2 spring screws to remove the middle bracket.
.
Rotate the bracket a little in counter clockwise direction to get it out of the PRISMAsync. Be
careful with the fixings that hold the PCB boards on their position.
