Riso V8000 master with wrikkels on drum

[Risocenter]

If my V8000 is making a new master and putting it onto the drum (first and sec drum) there are existing a lot of wrikkels to the master. The result is of course a damaged image.
The master is fitting well under the clamp.
Has anybody experience with this phenomen.

Not on this particular model. However, on other Riso models I have seen this when the master roll spins too freely causing a lack of tension which results in wrinkling. Also, make sure your master material feed path is free from anything that will cause it to skew. The leading edge of your master must be even from side to side under the clamp.

I remember from the past if I had this problem the cause was in my case the use of a KATUN master roll.
It means: no original Riso. Other posibill causes are mentioned already.
