es5540c e091 code

[JVC]

Hello

I have an es5540c that is throwing a e091 jam code. I have seen this a number of times in the past and reformatting the hard drive and updating firmware always has taken care of the issue. On this machine it does not. Looking in the service manual and online I am not finding much info. Basically the manual says to check the connectors on and then to replace the sys img lgc and hdd boards. Does anyone know if one of these is the culprit more than the others. I don't want to just order all of the boards. Any help is much appreciated

E091 is a jam caused by a failure in communication between System and Logic.
To test, I would use 04 Test Print Mode...

"142" will output a test print from the Logic Board
"70" will print a pattern from the IMG Board
"33" will output a halftone from the System Board

"142" should not produce the E091 since it is generated from the Logic Board and sent to the LASER

The other codes should help narrow down the suspect.
