A friend and I purchased a GR 3770 a few months back. It's taken the whole summer but my friend finally got it running again (with much help from the fine people in this forum I might add )
Now that we've run a number of test prints with all the drums we have, we've concluded that the drum screens need to be cleaned (or replaced?).
The documentation I have doesnt mention anything about this process. Does this mean we should just be buying new screens, or worse, buy a new drum? It seems a little extreme to have to go that far.
I'm looking for a something like a step by step, best practice for going about this process. Also, what kind of cleaning materials, chemicals are best suited to the job?
Thanks in advance for any advice.
