Hey guys,
I've been having a problem lately with the black drum (copy count: 777,534) on my Riso MZ. When I try to make a new master, the machine tells me that the master is stuck in the master disposal box and to remove it, which it isn't, and then that I need to manually remove the master. After a few goes of this, it eventually makes a new master but sometimes the previous master is partly ripped and still stuck to the drum underneath the new master. I've attached a photo of what it looks like when I pull the drum out to remove the master like the machine asks. It's happening on both sides of the MZ and only with my black drum. I recently replaced the 'master disposal belts' (rubber bands) on both sides of the machine thinking that it might be a problem with those but that hasn't seemed to help. Somebody suggested in another thread for a similar problem to try cleaning the clamp plate and clamps and to lubricate the pivot points, which I did, but that hasn't seemed to help either. I've also noticed that the black ink is causing the masters to yellow quite a lot, which I hadn't noticed before unless the masters were left on the drum for quite a long time. I always use OEM inks and masters too. Does anyone have any ideas of what the problem might be and how to fix it?
Thanks in advance!
Dan
