Repairs and Adjustments
Replacement
1. Unpack and visually inspect the new parts.
2. Install the EPROM memory from the old CPU board onto the new board (refer to Figure 1).
3. Position the CPU board, screw in and tighten the five mounting screws.
4. Reconnect all cables.
5. Replace the right cover and close the control panel.
6. Restore directory and parameters from the directory (MENU * 9).
7. Perform a remote readout (if the function has been enabled).
8. Perform a scanner calibration (MENU 8 0).
Note: It is essential that the E2PROM memory "stays" with the machine, because this memory
contains:
- The consumables counters.
- The counters of the number of printed pages.
- The remote readout counters.
- The network options (FSI, GDF, kit LAN).
