MEMORY BACKUP

IC1 (RAM) of the RAM Board connected to the Master Board stores the setting/adjustment
values set in the Tech. Rep. Modes as well as the counter counts. The Backup Battery is
mounted on the RAM Board to prevent the contents of memory from being lost when the
power cord is unplugged or the RAM Board removed from the copier. The Backup Battery
requires a voltage of 2V or more to retain the contents of memory.
Important
As noted above, the RAM stores critical data. If the RAM Board has been replaced with a
new one, memory must first be cleared and then all settings be made again. It should also
be noted that the RAM Board should not be replaced at the same time when the Master
Board is replaced.
