MEMORY BACKUP
IC1 (RAM) of RAM Board PWB-R connected to Master Board PWB-A stores
the setting/adjustment values set in the Tech. Rep. modes as well as the
counter counts. Backup Battery BAT1 is mounted on PWB-R to prevent the
contents of memory from being lost when the power cord is unplugged or
PWB-R removed from the copier. BAT1 requires a voltage of 2 V or more to
retain the contents of memory.
Important
As noted above, the RAM stores critical data. If PWB-R 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 PWB-R should not be
replaced at the same time when PWB-A is replaced.
