MX-FN11 - (MX-M283N/M363 Series/M453 Series/M503 Series) 
 
 
2. General:
 
The following is about handling the “F1-37” error that can occur just after 
replacing the finisher PWB for serving.  
Replacing the finisher PWB is now what is causing the “F1-37” error, the error 
occurs for the following reason. 
 
(Reason for occurrence) 
Memory on the finisher PWB holds finisher-adjusted value information and 
checksum values, when the power is on the adjusted value total and the checksum 
are compared and the adjusted value is checked for correctness. 
However, if the memory with of the finisher PWB for servicing does not have the 
checksum value, the “F1-37” will occur. 
To make sure that there are no input errors in the finisher adjusted value, the “F1-
37” error occurs. 
 
 
 
3. Measures:
 
When replacing the PWB, confirm the finisher adjusted value written on the 
finisher PWB and then input this value into the new finisher PWB. 
(1) Before replacing the finisher PWB, take note of each setting value from 
simulation 3-10 (finisher adjustment). 
(2) After replacing the finisher PWB, input each of the values noted from 
simulation 3-10. 
By inputting each of the setting values from simulation 3-10, the “F1-37” error 
should not occur.
