Broken image on non-operator side

[eg101]

Have a Pitney-Bowes DL250 (I understand it's a early Panasonic Digital copier). It had a solid black area 1-2 inches wide on the drum.
After cleaning the drum and re-assembly the black line is gone but the print is faded and broken on the non-operator side. The operators side of the copy looks fine.
I don't usually work on Panasonic, but on Konica and Minolta copiers. I guess I put somthing back togather wrong but I've had it apart 3 times now and still can't find anything. I've cleaned coronas and laser glass, wiped the drum again with a dry towel, cleaned and dusted the cl blade. Nothing helps.
Any suggestions apppreciated.

Sound like Panasonic DP250 if it is we had some problems like that. Is it in poorly ventilated area and how are the Drum Ozone filters (It sits above transport bed 1 screw 1 connector) also there is a weight on rear of drum if it is missing can give weird CQ. Do the light image correspond to where the black image was? Did you clean the laser slit glass

The black area is gone since I wiped down the drum and has not returned. Yes the light area is where the black strip was but it is much wider. Yes, I cleaned the slit glass (and Coronas).
The image looks good on the operators side but fades till 90% of the image is faded or broken on the non-operator printed edge.
Tell me more about this weight that is supposed to be on the rear of the drum. What size is it, Is it metal?

We are assuming this is a DP250/350, that is only series that used weight on Panasonic. yes it is metal. It looks a lot like a Donut that u use with batting practice. Here is another thing you can look at the developer locking bracket comes loose and developer does not engage evenly.
Good Luck

light area

was the black band of toner stuck to the drum and if so what did you clean it with? ck your corona wire height . also make sure dev tank is firmly/evenly engaged and that your "brush height" is even. after all that is time to try another drum. good hunting!!!

Sorry if I misled anyone about the model but I was now informed that it is the same as a Panasonic FPD250 copier.
Does this change the previous suggestions. and Where should I look now.

You might wanna try cleaning the entire optical system. And if that doesn't work wipe down the LSU. But if you take out the LSU make sure that you put it back EXACTLY how it was set in there the first time or your immages will be off drastically.

I've had this problem happen before and it ended up being a bad developer. Most likely they're using after market toner for this machine (judging by age) so you might wanna look into that.

Yes his is model I was describing. I have run across this Drum problem several times. With OEM toner and developer. It was always in poor environment, poor ventilation / clogged Ozone filter. Toner looked like it was melted on Drum. Cleaning drum is not recommended (but we all know we do what we have to do to get machine up & running) saying that I would order a drum after I cleaned it. Cleaning an organic drum is always a crap shoot. If your CQ problem corresponds with where you cleaned, your drum is shot, especially if is close to 120k. If it is slow fade where only have 5 to 15% good image it is Developer locking shaft, and if it is 20 to 30% with poor linear track lines it is doughnut weight is missing. sorry I cant give part number for weight but I deleted parts manual

Did a 120k pm call - Drum, Developer, web - and problem is gone!
Thanks for all the suggestions.
