MEMORY BACKUP
23
IC1 of RAM Board connected to Master Board stores the setting/adjustment values
set in the Tech. Rep. Modes as well as the counter counts. 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. Backup Battery
requires a voltage of 2V or more to retain the contents of memory.
Important
As we 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.
