Riso GR3750 STUCK IN "Ready to make Master" mode

[ybnews]

My GR 3750 won't print, test copy or make a master.
I've removed & re-installed the master roll several times.
It doesn't advance the master material or cut off excess master material.
I turn off machine & start again, push Start and get "ready to print"
or "ready to make master" over & over again. Ocassionally it reads a T2 code.

Any suggestions on what to try next?
Thanks,

I would start with this. Some times you have to have a minimum number of copies entered in before the machine will do anything. Try putting in the quantity 50 before you start to make a master. If you can not key in anything then I believe you have a larger problem. Hold down the MP and the LP buttons while the machine is off. Turn on machine. This should put you in test mode. Type in 90 and press start. This is a reset of the machine. If this does not fix it, then I would point to a bad board. They that and tell me what happens.

At my self sorry about the last sentance it is early and I need more coffee. "try that and tell me what happens" Please do not push in any other codes while in test mode. It will only cause you troubles.
