Report Noristsu QSS-3202 Sd with scanner with ARCNET communication error 6901-6219 in Noritsu Help and Support Posted April 8 Hi Sir , lot of thanks for the recomendations . After closing the Noritsu software , ran for the self check application on C part of the computer . The first line PCI-LVDS/ Arcnet have this message : PC s Arcnet Control PCB is not installed . Possible causes are : PCB is not installed , Device Driver PCB is not intsalled, Device Driver to control PCB did not process correctly . The last few days after the messages of Arnet communication errors appeared , the properly shutdown ( close down check , F , quit application ) coudnt be done , only could shut down as a normal computer . Today just changed another pcb processor board beside the magazine , after that the problem still remained . And tried to recover to last few days before the error . The computer seem dont have this feature to support . What are the possible procedures need to be done ? Million thanks .
