Roland VG VG2 640 Damper question

[Joesignshop]

Are there o-rings between the damper and the printhead on a Truevis? Have it apart and don't see any o-rings? Having possible air issues on Lt Magenta but Lt Cyan is working perfectly. If I do a powerful clean Lt magenta comes back for a day and then get staggered loss on test print, telling me its not a faulty head. The captop is new. So trying to figure out if there is a slight air leak over a 24 hr period, somewhere that's dropping half the head.

Not certain about O-rings, but it certainly sounds like either an air leak in the line or you need a new damper.

On the SG heads, there are rubber seals on top the print head on the white plastic part. I don't think you can change them, they seem to be molded into the plastic.

The seals are (stupdly) built into the heads on these machines. I just recently had to trash a perfectly working head because of this.
