Riso GR 1750 C-60 code

[kjv1611]

I have two 1750's with the same error code c-60. Any suggestions on what the problem is?

If i am not mistake it seem to be ink overflow. I am 5 years not doing on this machine.

T-4 is an ink over flow on the GR machines not C-60

In my experience a C-60 is a code for one of the safety switches on the paper tray being tripped. I have found that the one on the top gets stuck. You should be able to see a metal bar running under the charcoal black plastic where the "card lever" is. This metal bar will get stuck up and causes this code. Push it down and see if it goes away. If not there is a chance that this swicth has gone bad. There is also a switch on the lower side of the paper tray that will cause the same error.

C-60

Been a while since I've worked on these guys, but I seem to remember that sometimes when people lift the machine by putting their hands under the paper feed tray, it bends the safety bar. Best way to check, is shove your hand under the tray and if the bar doesn't move up and down freely, that is prob'ly your problem..... I was always on at the salesmen for doing it when they moved the machines.
