You have two hopes.
1. Many techs will take the sticker off the head and stick it somewhere on the machine so that it can be read ( you cant see the head rank sticker when the head is installed).
2. Often times the parameter sheet is printed out and stuffed in the left hand side of the machine. Take the covers off and check.
I have a 48" mutoh falcon outdoor and today it shut off in the middle of the print. I've checked all the plugs and outlets and everything looks good. I called mutoh tech and they said it may be a fuse located in the circuit panal box. I open the circuit panal box and I can't seem to find the fuse. Can anyone help? Thanks BIGFOOT
