Did you drop toner inside the machine?

off course not, but even if i did that wont cause the fading/gradient effect

i assume, the alignment between drum and blade is not even, i will tray reassembling again

what i dont under stand is why the print is so light even with density Level Full

mean while i bought a new after market blackIU and machine is working good(how long it will last that remains to be seen)
