Konica c500 What's wrong with magenta?

I have been fiddling some more today and my magenta sandiness came back. I wonder if a new magenta developer unit would solve all this, simple as that?

Is weather now my biggest problem? Now I've had a success. I hope somebody in-the-know reads this. Having only 1 brand new drum to work with, I took is from the black and put it in the magenta--switching charge assemblies too. Now I have a situation where all 3 colors are blotchy and unusable for professional work. Could it be because it's NC in July, and it's probably 90-some degrees in this room at 97% relative humidity? (according to weather website). ALL 3 colors are just about equally blotchy. As far as my 45-20, I now have the sensors on, and it hasn't been coming back since I bent a little bit on the shiny spring-steel thing behind the front of the registration unit. But I'm sure it'll be back. I haven't seen the last of 45-20, I'm sure. If I bought an air conditioner and put it in this room, would my blotchy problems start getting better?

Any one suggested the drum potential sensors yet? Ive had these give up in the past and cause gritty copies. I would try replacing it (may have to replace the dev as well).

This machine is FINISHED. I'm TIRED of it. This 45-20 is dead-set stubborn. No matter what I do, there's no way of getting out of spending at least 2000 dollars on it. Thanks, friends. The end.

Thank you for everything, Mr. Rogers. And I would respect you to do it. I went on EBAY and bought another one. I'll shove this one out on the deck and cover it up with plastic in case I buy a big boat and need an anchor.
Actually what I'll do is fiddle with it by swiping things off my good new one to try theories on the old one. Frankly PCRB is my first choice, and you can't substitute that, but possibly transfer belt assemblies can be switched. Anything that even changes the behavior without necessarily fixing it is a giant step. Could be just registration unit. Who knows without some spare parts? A tube caddy went a long way in making a professional TV repairman out of an ordinary boob. Pluck out a suspected tube, stick in a new one, and if the vertical hold stops rolling, it's fixed.
But this one is out the door--for sure. Thx, friend--HTF
