Weird problems on an MPC3003.
Changed the developer unit lately because of white stripes, only in K mode.
After the change no problems, black copy and prints were good. (no stripes)
However, about 4K counts later, again white stripes. (see photo's)
cleaned the laser, notice that again the developer rol is not completely filled with developer . .
Anyone a solution or explanation why it returned after only 4K ?
Thanks in advance
