Solution
CAUSE: Problem causing CE301 by operation of screen transition of browser application. Problem with
CFA14 caused by repeated operation of launching OpenAPI application / MFP standard function(copy
etc) from IWS application
SOLUTION: Some Special firmwares are available: GG1R9
should resolve both these error codes.
If CFA14 is not resolved then update to GG6R9
which is available for most models in this series,
should be available for the other machines by end of March 2018 .
