Does it stay light after 10 - 20 copies? Could be impression roller or inking issues inside drum.
Good luck.

Re: Riso EZ370 light copy quality!!

When you say you replaced the drum in another machine, can you be more specific?

Did you:

1. Take a drum from a different machine, install it in this machine with the light CQ problem and it worked fine?

If yes, and you make a new master, is the CQ still good?


2. You took the drum from the light CQ machine and installed it in a different machine and the CQ looked good?

If yes, was the master that was made on the original machine still on the drum and looked good on the new machine?

or did you just take the drum from the light CQ machine, install it in a different machine and make a new master and CQ looked good?
