a. To Remove the Motherboard
1. If you are replacing the motherboard with a new board, print the following from the
Functions menu:
• Configuration page —records the customer’s current Setup configuration.
If you are installing a new drive you will need to reinstall system software after the
new motherboard is installed. The Setup configuration will be reset to the default con-
figuration when the motherboard is replaced.
• Font Lists— details what PostScript and PCL fonts are resident on the iR-M1 HDD.
Along with the fonts provided on the System Software CD, the customer may have
installed additional fonts that will be deleted when the motherboard is replaced.
2. Power off and open the iR-M1 as described on page 4-3 and page 4-4.
3. For stability during service, remove the front panel as described on page 4-6.
4. Remove the power supply cable from motherboard connector J29.
5. Remove the two fan cables from motherboard connectors J25 and J26.
6. Make sure the UIB cable is removed from motherboard connector J30.

copier interface board” on page 4-16).
