Just before Christmas we bought a used Fuji IP1 cheap. It took us a while but it's been working great for about a month. Yesterday the IP1 stopped after completing a board but before exiting the board out the conveyer. No error message, no alarm bells - just stopped. I used the CLR OFF button to manually convey the PCB out the conveyer.
The IP1 then stopped at random spots on the next two PCB's. Again, no error message or bells or apparent reason for stopping. Although the machine would respond to key presses of the control panel, I could not get the machine to continue placing parts. After I opened the safety door the machine displayed "emergency stop - safety door" as normal but would no longer respond to key presses of the control panel, even after the safety door was securely closed (continued to display "safety door").
I tried loosening and tightening all the PCB's and connectors inside the front right circuit board area of the IP1 (which took me about an hour). The same results - the IP1 stopped at a random spot in the assembly on the next PCB and refused to continue on. Turning the machine Off and ON did not fix the problem and I now had three partially completed boards.
Resetting the memory and resending the proper data and program data solved the problem for a while then the IP1 stopped again at the end of completing a PCB without running it off the exit conveyer. I reset the memory again and completed the run without further problems.
Does anyone have an idea of where the problem could be?
We use the machine about 8 hours a week and it usually works great.
Regards,
Bert
