I am currently working on a Mimaki JV3-160SP which is having serious problems caused by something to do with the Y axis. It started with a Y axis error 41 problem so I changed the motor with a known working one which solved the problem for a short time, after which there was a burning smell coming from the main board which turned out to be one of the NPN transistors which control the Y axis motor so I switched the main board with a known working one. This worked for a very short time and then during a print operation the carriage came to a halt around 50cm from the capping station and some error appeared on the screen but I turned it off before I could read it, it then failed on afterwards as the power supply's over current protection was kicking in instantly. I replaced the failed NPN transistor and it worked again, I did a cleaning operation then the same problem happened again in the final stages of the cleaning operation while the carriage was returning to the capping station, I haven't looked at the main board but I assume that another transistor has blown.
I need some ideas on what could be causing the problem as I don't really have any ideas on what to do at the moment. The carriage doesn't seem to be getting stuck on anything and the rail it slides on is well lubed.
