I got a ecosys PA2100cx with error code "call service 7914", before this error appear was printing in blank
It seems that have a problem on developer unit, but I don't know how to resolve this problem

Does anyone know how to resolve without replace the developer unit?

I've had this happen before, but with a new device. It must have taken a beating while being shipped. Reinstalling helped. Have you tried that? Sometimes reseating parts helps.

I already did that, but I think it must be something about the flex cable. I'll give it a try once again.
