You Guys helped out and I would like to return the favor.
Sometimes when your in the middle of a drum change you may not think of this.
Most shops have the lights away from the work station your at.
regular light bulbs are not usually a problem
The one thing I forgot was the newer power saving bulbs are NOT the same thing at all.
Yes there very good at getting the most light for the watt
BUT there is a lot of UV in them "sunlight" is a good source also..hahaha
Well the problem was the drum was exposed to this.......not for long
less that 30 sec. out of the box and plastic wrapping and so on.
Installing the drum and running test revealed a image that would not go away...even after 200 copies.
BAD drum? its happened sure.
ordered another one and 2 days later I started to change it out.
Image was gone.............. and even looked as if it was not going to have to be changed at all.
well nit pick it to death and you could find anything you want on the ghost image.
turns out as many of the tech's do is make it work and 99 % of the time thats what you do!
The point is the replacement drum Was exposed to a light source that had a lot of UV light from the power saving bulb.
The change out was not really needed for B&W pic's or copy.
The ghost image after so many cycles finally did go away.
BUT.................If you can dim the lights.........or..........
Shield the drum like it was in a Dark room photo shop.
AND on color drums.........10X's worse
Hope this helps......................
