Cleaning Station:

Can someone in this knowledgeable group tell me why you need a 20 pack of Cleaning Station blades? Do they get messed up that often?

It constantly rides on the pip to clean or squeegee the oil. Ink tends to hang up at the tail of the pip at times and could nick the blade. That is what causes the wiper scratch through the print. It wears like anything else. If you keep your oil clean and wipe off the blade from time to time it will last longer. Also, the adjustment of the blade gap is important. The dash spotting from oil getting under the blade is caused by too wide of a gap or a worn blade. Bottom line is, yes you need an inventory to be safe. Frank

The cleaning station on the Ultra is quite different. It is wise to order the wetting and sponge roller for back up. Wetting roller has part #MPT-0321-54

Turbo/Pro: Dear Ice Kevin asked: "What are the causes for image oil dripping from developer shoulders on paper exit tray?" Answer: Imaging oil dripping into the exit paper side can be cause by 1. PIP Foil riding on the PIP drum shoulders 2. Excessive Flow rate to the Cleaning Station or Deteriorated /expand C.S sponge roller 3. Excessive Flow to the RR, or RR station Problem 4. Air Knife malfunction The following Point should be check when imaging oil drips from the developer drum spacers PIP Foil: -------- * Check that the pip is properly installed and that it does not ride on the drum shoulders. Cleaning Station: ----------------------- * Imaging oil flow rate is correct (25-30 mm fountain height). * The sponge roller is centered between the pip drum's shoulders. (correct sponge roller's length is 352mm). * The plastic shields (black liquid shields mounted on the sponge roller shaft and squeezer) are mounted on both sides of the shafts. They should be close to the edge of the sponge (~5mm from the sponge), and on the squeezer they are suppose to lean against the squeezer shoulders. RR station: ----------------- * Imaging oil flow rate is not too high. * In the wetting tray assy. Check that the bottom edge of the inlet pipe is actually touching the tray's floor and there is no gap between them. if there is a gap- (If that is the case consult your FSE). A gap could cause the imaging oil to climb up along the inlet pipe and from there to the bearing and the pip drum shoulder ending at the developer drum spacer (at the operator side). The Air Knife: ------------- * Disconnect the blower to check its influence on the problem. If there is an influence- inspect the air knife assy. for proper installation and operation. If all of the above didn't help you can try to trim the sponge. You can trim it up to the size of the cleaning station blade. The cut should be smooth and straight and the black plastic shield should be push close against the sponge. Thanks Eran Mallach Technical Department

Can anyone help me with an imaging oil splash problem? When we print > solid coverage, we get random spots throughout the piece which looks > like imaging oil is preventing the ink from adhering.

Dan, I have seen this problem come from the spraying rod in the cleaning station. If it is at the wrong angle or ink is plugging up some of the holes, it could splash over the tray. Also, the little black splash guards should be in the right place on the end of the rod to prevent splashing or the flow could be too high if the cleaning station and your blade seem ok. Just some thoughts on the problem. Frank Barbalace Digital Imaging Resources

Dan, a few years back be were getting your described problem and the eventual fix was to cut about a quarter inch of foam off each side of the foam roller. Seems that the "off the shelf" rollers migrate the oil to the edges and spray it around. It could also be oil dripping on the blanket or improper eccentric (silver bullet) pressure on the cleaning station. Mike Hay, Mossberg Digital

ULTRA: I find that it is wise to inspect and clean the station from time to time. Replacing the sponge roller when needed.

Hey all again today Please tell me which way you turn the oil flow valve to decrease oil flow to the cleaning station? And or how many turns in what direction is correct if it is completely closed. Thanks Grayson --Counterclockwise is less flow. You will close the valve in that direction...Backwards? Yes. Frank Barbalace
