taskalfa 3500i light image

[Gab]

MAchine works fine for 2, 3 weeks and then light image. I execute U132 and it works fine for 2,3 weeks and then the same.
I cleaned corona, optics with no result
Machine is one of a load of second hand copiers (all counters under 200k copies) . Because i had a lot of toners from these machines not full i transfered toner from one cartridge to an other to fill it. Toner are genuin Can it be toner? Perhaps toner chips or something else?

the chip does not lighten the image ... Check on the surface of the drum if a good image is formed (cutting the print) then the problem is in the transfer unit. Sometimes a bearing in the ends is damaged.
