panasonic dp 1510 white patches
yesterday i finished the service (maintenance kit 120k) on a panasonic 1510 and when i make copies or print from pc i see white patches on a particular area of the paper always at the same spot.
I have changed mag roller, catchers,Assembly, Cleaning Blade, and of course drum , blade etc
Finally i tested another process unit and the same problem.
Any suggestions?

Hi If I remember correctly it is to do with the earthing or ht to the dev unit. Remove sliver plates on the rear of dev unit give them a good clean with an abrasive pad.
Good luck

Re: panasonic dp 1510 white patches
If it were me, I would stop the machine, as best I could, so that the area of print in question is where you can see it on the drum. That way you can see if it is developed on the drum or if its a transfer unit issue. Then go from there. I cannot say I have seen this before.

Copiman i can see it on the drum , when i stop the machine i see an area on the drum with characters not bold like the rest of the surface. Still remind you that i've changed drum , mag roller etc. Tommorow i 'll test another lsu ,,, what else?
and will clean sliver plates as gordie suggested
