just a line about .5 inch or less across the top of regular 8.5x11 paper (LEF). Changed DV units, changed PM units, adjusted voltage...
Still will run clean for 3000-5000 copies then it appears, looks like a buildup of toner on the grid, once clean, will again run 3K-5K clean.
I am swapping charge units off another machine today, ill post if that fixes, but I am at a loss, machine has total of 780K, its all printing no copies.
Aways prints from LCT, face up. Rollers are new, PM is new, drum is new.
Any ideas...
