riso cz100

[RWAFA]

Hi guys, I have got my machine riso cz100 which is not responding if I press the start button, it only pushes the master and lift the tray paper, from that it doesn't feed the master to the drum, it stays as if it's feeding the master to drum until I switch it off, i tried to change the drum home position sensor but nothing changed, does anyone has any idea of what could be the problem, please help I'm stranded.

I don't know if that many of us check here that often.
That being said, you might try resetting the machine by holding down the reset key while turning the machine on, and holding the key down until the initializing motor sounds get quieter.
You might also double check that the master material is loaded correctly.
Hope that helps.
