taskalfa 3500, 4500

[Gab]

I just received a load of taskalfa 3500, 4500i second hand machines.
In Most of these machines toner bottle are empty and the image is too light . This happens to these machines only . Those machines with toner not empty are ok. I swaped toner to a machine with empy toner from one with full toner but copies remains too light . If i perform U130? or the problem is else?
I am new to those machines.

Sometimes we have to take the laser apart and clean the mirrors.

Make sure the mag roller on DV units still have their full black coating..
After cleaning everything , do a DV refresh, this may help.

I like this one. You'll be surprised how dirty it is inside the laser. =^..^=
