OTHER MECHANISMS
26-1. Memory Backup
÷ RAM Board connected to the Master Board stores the setting/adjustment values set in the Tech. Rep. modes as well as the counter counts. ÷ A 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 is removed from the copier.
IMPORTANT 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.
