User s Manual rev 5 Page 75 10 7 2 Controller Board Isolated Test One useful diagnostic technique allows the plotter to be tested with the Processor and Controller Boards isolated In this condition the Controller is configured to generate its own data internally without need for printhead data to be supplied from the Processor as is the normal case This allows the wellness of the Controller to Printhead data channel to be established If a problem arises in which the Processor Board is suspected this test can help confirm this To perform 1 Power down plotter 2 Remove the Processor to Controller Board interconnecting cable 40 wire ribbon 3 Apply shunts to jumper locations JP5 JP6 and JP11 on the Controller Board 4 Insure that media is installed correctly the transport mechanism is free and the printhead locked down 5 Power up plotter Since the boards are isolated pay no attention to the Display The 15 second initialize period should elapse then the media should advance approximately 3 8 inch 10 mm 6 Momentarily press switch S1 on the Controller Board A test plot should then be produced across the entire printhead consisting of a pattern like the self test Zig Zag pattern but smaller The plot will come out very slowly about 0 1 inch sec 2 5 mm sec The plot will be performed under Energy Level 1 conditions so that slow media may not blush completely If this pattern appears okay it is reasonable to assu
