T-4 Code??

[ybnews]

I have two Riso GR3750's. One of my drums kicks out a T-4 Call Service code in both machines. Any idea what this is and how to solve it?
Thanks,

This is an ink overflow inside the drum. Pull out ink tube and look in there with a flach light. It you see a massive amount of ink in there chances are some thing has failed inside of your drum.

Go with what joelsa12 said and look inside the drum.Other than a bad connector on the drum side you probably have and ink overflow
