theberah Posted September 13, 2011 Report Share Posted September 13, 2011 Dear all Please help me to solve arcnet comm error on 3300 LPP-750. I checked all optic fibre cables (disconnected and reconnected) & cut their ends to make sure they are ok. I checked input /output voltages (A.C & D.C) from all power supplies & find them ok. I also checked voltages on Printer, Processor & Laser I/O and Control PCBs. I checked communication between pcbs on System version check & find out that only PC-Scanner interface, Colorimeter & NMC Net order are communicating Please where else can I check to solve the problem?
