Mp 9000 random smudge... I'm gone mad!

Ok, new idea. Some liquid is finding its way onto the drum surface, maybe lubricant from an overactive can of wd40. Or, there may be contaminent in the toner .

Going way back into the dim distant memory of my past I suddenly thought about the old dye line plan printers and the slightly corrosive ammonia fumes they used to give off. Your problem machine doesn't live next to one of those does it?

No... Only Mfp in that shop

Big trouble in little Sicily!

Could be a stab in the dark...but have you tried looking at a lag in Drum drive maybe...

what does 'ammonia paper' do to machines?

Gecko pee(weak ammonia?) does wonders to drums and circuit boards...

Mouse pee is a tad better than gecko pee, probably because there's a lot more of it.
Mice wee stinks bad and corrodes circuits boards quite good....


Never tried ammonia directly on a selenium drum.

Ammonia cleans grubby carpets quite okay though.

What about some type of airborne cleaning agent or air freshener being sucked up by the airflow through the machine while in standby mode for a long period of time?

Like chlorine, at a public pool? Within a few months everything ferrous will be rimed with rust. =^..^=

Re Chlorine and iron.

Yes chlorine rusts iron, hydro-chloric acid is by far a lot quicker.
As you probably know, Ferric-chloride eats copper rapid, this is how circuit board tracks are etched.

Interesting point though BC.
I wounder if chlorinated water rusts/oxidises the iron inside the human body. Could this oxidise effect be a cause of anaemia(lost of iron/minerals) in some people ????

Chlorine is neutralised by sunlight, but how much sunlight for how long before we should drink the city tap water? Here in our location the "water board" places "booster cylinders" of chlorine directly inline with residential housing water mains. Those booster cylinders of solid chlorine have no reaction to sunlight before the water comes out of the house tap. Does this chlorine create an oxidising effect within the iron of a person body before it has a chance to react with sunlight ?

An of cause every other chemical placed into the city water supply. Eg. Aluminum Oxide (Al-Ox). Fluoride.
Our water supply comes out pure white some days. We have to run the tap for a few minutes just to wash.

Sunlight will burn the chlorine off the first 12 inches of water in a swimming pool in about an hour.

UPDATE!!!

Hello guys, i'm almost sure the problem is solved....last thing i changed three weeks ago was the HV Board for the charge unit, till now (crossed fingers)...no problem!!!

Thanks for getting back to us with a result, not many techs who ask for help can be bothered. Hope it stays fixed for you.

I would say, Sicily is saved!
