Operation
Operation/
Procedure
1. Press the [EXECUTE] key.
The following operation checks of A2 copy board are performed.
1) SRAM check
2)  Retrieving side matching DRAM test
3)  Reference side matching DRAM test
4)  Retrieving side reducing DRAM test
5)  Reference side reducing DRAM test
6)  Retrieving side synthetic DRAM test
7)  Reference side synthetic DRAM test
After completion of the operation check, if there is no abnormality, OK is displayed. If there is any abnormality, NG is
displayed.
Display in case of an abnormality in the operation check
