I tried to install a new MCU on docucolor 242 and it came up with 124-315 code. This has to do with serial number mismatch and I am surprised about this since i used the same NVM chip from the old board. I did the serial number serialization procedure and it was successful but the fault code persisted.
On going through the manual i was asked to check NVM locations: 700-600, 700-601, 700-602 and that the settings on the three must be the same. That of 700-601 on my machine was different, but it is a read-only location...i could not change the setting to match with the other two.
Could someone advise how to resolve this situation.
By the way, the new MCU i was trying to fix is working perfectly on a docucolor 260....same MCU part number for both machines.
