Re: panasonic dp 1510 white patches
It could be a bias issue like it changing before it should. The top part seems ok and then it fades towards the trail edge, right? You should have somewhere around -430Vdc for bias measured on the front of the developer unit. Did you change developer? If not how many copies on developer?
If you have another laser unit you could use, I would try that. Also ensure you have a good drum ground. Have not seen drum ground issues, but would not rule it out.
