NY PRINTING,
Interseting I havent seen or thought of the center baffle as a cause of spitting.
Donor Roll Center Baffle Alt PN 604K42070. I do clean the center baffle when I'm cleaning the manifolds I don't recall it building up toner on it though sometimes a little developer mostly on the ends...
I would like to see a close up picture of the spitting.
I think of there as being three sources to the general problem.
1) Toner falling out of the developer housing. ie. Build up/bridging on the manifold/baffles ,due to lack of vaccum or cleaning.
2) Runnig the housing over toned.
3) Environment. Now for environment I'm not talking about the outside of the printer. I mention this and this is why I would like to see a picture because what you call spitting may be "Streaks". I think of this as being more common.
Streaks can be caused by developer or toner beads on the donor roll getting trapped in the 8 wire modules.
For streaks in Magenta ONLY, check the right X-Tower Temp rightTowerTemp nvm loc 7430 and the Left X-Tower Temp leftTowerTemp nvm loc 7429) See if the temperature difference is greater than 5 degrees F. If this is the case you must resolve the temperature problem first.
Lastly
I didn't mention gremlins before but worthy mention.
As an operator my personal favorite was the paper gremlin.
Yes the temperature and humidity gremlins are a colse second.
They are more technical TECH excuses as to why they cant fix the problem.
I have ran an iGen3 in a open warehouse 60-90 degrees with both high and low humidity outside the press. Keep in mind that the iGen has a ecology/aka A/C unit on the backside which takes care of the inside of the press. Air conditioners automatically act as dehumidifiers when they chill the air. This will cause paper problems feeding, deletions mostly so a humidifier maybe needed.
