roland cutter CAMM1 problem issues

[timson_ads]

hi everyone, i have here roland camm1 plotter and it has some problem now, the fuse in mainboard keeps on blowing, we try to check voltage and power supply its seems ok, but when we replace fuse, and power on, it keeps on blowing the fuse.

do you experience something like this? or do you know what to fix here?

thank you in advance.

where are you plugging it in? check the voltage at that receptacle.....bet your getting some short or spike in it.

A lot of blown fuses are from bad connections, usually the ribbon cables. Taking them out to clean the contacts also gives you a chance to look for bent pins or scorch marks. Also check the cables that move along with the cutter, sometimes they wear through the coating, and the lines arc against the chassis.
