Case 1
Cause
EEPROM trouble,
Insertion of EEPROM
which is not initialized or
defective.
Check &
Remedy
1. Check that the
EEPROM is properly
inserted.
2. Use SIM 16 to cancel
the error.
Case 2
Cause
SCN PWB EEPROM
access circuit trouble
Check &
Remedy
1. To prevent against
deletion of the counter
data and the adjustment
data, record them with
the simulation. (When a
printer option is
installed, use SIM 22-1
to record the counter
data and the adjustment
data.)
2. Replace the SCN PWB.
3. Use SIM 16 to cancel
the error.
