This machine has about 300K on it. When copying from the ADF I was getting a void down the middle of the copy paper about 1" in width, when copying off the glass I was getting a black line approximately 1" in width running about half way down the middle of the copy paper in the same area as when I copied from the ADF. I replaced the 300K PM kit (Fusing unit, Drum unit, Developer unit, etc. I cleaned off the laser glass and I went into service mode and ran "refresh drum" and now half the copy is blank. Any thoughts or suggestions would be appreciated. I'm not certified on Kyocera so please be as specific as possible. Thank you.

Did you run a u130 to fill up the dev unit? that sounds like the issue is that your dev unit isn't full of toner and causing only half the page to print."In a cruel and evil world, being cynical can allow you to get some entertainment out of it."

Thanks for the quick reply Kidaver. No I have not run U130, but I did run U100 and U113. I'll run U130 and let you know my results. Thank you much.Comment

That's a good place to start. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Ok. Ran U130. Mag roller is fully coated but still only getting about half of the image on the copies/prints. The side of the copy towards the front of the copier is blank. When I stop the copy mid cycle, there's no image on the drum. Any other suggestions? Thanks again.Comment

Next thing to do is to emergency stop the machine while the paper is against the drum (open a cover). Is the latent image properly developed? If yes, it's related to the transfer roller.
If no, it could be a developing problem (bias voltage or toner distribution), charge (primary or drum ground), or exposure (CCD or laser unit).
How does a counter page print? Is the developing roller evenly covered with toner? =^..^=If you'd like a serious answer to your request:

When I stop the copy mid cycle, there's no image on the front-facing end of the drum (or at least its not developed) Mag roller is fully coated. Counter page prints out same as copies (blank on the side closest to me when I stand in front of the copier). I agree it has to be a developing, ground, primary charge, or laser unit (long shot) problem. Any thoughts on what simulations I can run to test it out. On Sharp and Ricoh I can play with dv bias, main charge, and print test patterns from their service mode, I assume I should be able to do the same on this machine but as I stated I'm not certified on Kyocera. Thanks again.Comment

OK. So you've ruled out the CCD, and toner distribution in the developing unit. It's probably not a transfer issue, but you won't know for sure until we get the latent image filled in. It's possible, but unlikely to be a laser issue. If this is a dirty environment, the lenses and polygon mirror could have a film of dust. This is a laser unit that you can disassemble and clean. NOTE: don't touch the polygon mirror surfaces. They scratch very easily. Use air to clean.
A loss of developer bias would appear as a void crossfeed, front to back, all the way to the voids. It doesn't sound like your symptoms. Same with drum ground.
I'd have to say that the only likely cause is primary charge, and there should be an obvious problem with the position of the charge unit, grid, wire, or wire cleaner. I'd just order the charger assembly to cover all the bases.
I don't know how simulations can help you here. =^..^=If you'd like a serious answer to your request:

Hi there,it sounds like your original problem is different to your current problem?Have you tried putting back in the old units to see if this changes back the nature of the issue?Comment

Re: Kyocera 2550
i have encountered and solved the same problems, try scraping dev unit groundings that should do itComment
