Error List
When an error that relates to the system boot occurs while running POST, "Critical Error" is output and dis-
played via the service port, and the system boot is interrupted.
The following can cause a critical error:
• The memory area under 640 KB cannot be accessed
• There is a faulty memory refresh
• There is an error reading/writing CMOS memory
• The CPU timer does not operate correctly
• The interrupt controller does not operate correctly
If the POST is interrupted due to an error other than those above, there may a system fault. In this case,
check the "Details of the Service Port Output" and look for an error.
If this kind of error occurs, the system cannot boot and the copier and print controller will not be able to com-
municate, and communication errors will occur with the controller after the copier has started.
