Digital BW, The Print

Thank you all for your advices,

yesterday I tried again with a KK1 and KK2 cleaning and ended with 
having emptied two newly filled cartridges. I will fill in the rest 
of the bulk ink (about 20 ml) to have some more test.

Did anyone have experienced or seen the mentioned horizontal 
misalignements ? Any ideas how they are produced? I really don´t have 
clou about them. I will scan the printout and post them here. 

As I said I had already two perfect prints in the beginning. All the 
mess started with the ink drops on the paper. Is there something 
disconected or ruptured? I think I have to sort out a few things. 

Here in Germany we don´t have Windex. I saw this is a usual Window 
cleaner. Does Windex have any special ingredients ? Can I just choose 
a similar product or is there any danger with other ingredients. I 
read that alcohol can make the problem even worser with some inks. 
Has someone a recommendation for a similar product on the german 
market?

Ingo
