Imagepress V1000 grainy black

[Artos]

Hi all! We recently purchased a v1000 printer. We are completely satisfied with it. However, the black separation is noisy and grainy. Magenta a little, cyan even less. Does anyone have an idea what could be causing it? What could be set to improve the quality?
Thanks!

Usually, the transfer roller is the reason for the grainy image.
Another, more expensive option is a dc controller.

I agree on the transfer roller.

Good morning.
A firmware version was recently released (DC Con 27. xx if I remember correctly), which fixed several quality issues.
Try adjusting the inclination of the blade next to the secondary transfer roller inside the intermediate transfer belt.
